 # git-next
 
-- Status: Alpha - dog-fooding
+## Trunk-based developement manager.
 
 `git-next` is a combined server and command-line tool that enables trunk-based
 development workflows where each commit must pass CI before being included in
 the main branch.
 
-## Features
+![Demo](./demo.gif)
 
-- Enforce the requirement for each commit to pass the CI pipeline before being
-  included in the main branch
-- Provide a server component that manages the trunk-based development process
-- Ensure a consistent, high-quality codebase by preventing untested changes
-  from being merged
 
-## Prerequisits
+See [README.md](https://git.kemitix.net/kemitix/git-next/src/branch/main/crates/cli/README.md) for more information.
-
-- Rust 1.76.0 or later - https://www.rust-lang.org
-- pgk-config
-- libssl-dev
-
-### x86_64-unknown-linux-gnu
-
-Additionally for this platform, to improved compilation times:
-
-- clang-16
-- mold
-
-See `.cargo/config.toml` for how they are configured.
-
-## Installation
-
-You can install `git-next` using Cargo:
-
-```shell
-cargo install --path .
-```
-
-Not yet available to install from `crates.io`.
-
-## Branch Names
-
-`git-next` uses three branches, `main`, `next` and `dev`, although they do not
-need to have those names. In the documentation we will use those names, but
-each repo must specify the names of the branches to use for each, even if they
-happen to have those same names.
-
-## Configuration
-
-- The branches to use for `main`, `next` and `dev` must be specified in either
-  the `.git-next.toml` in the repo itself, or in the server configuration file,
-  `git-next-server.toml`. See below for details.
-- CI checks should be configured to run when the `next` branch is `pushed`.
-- The `dev` branch _must_ have the `main` branch as an ancestor.
-- The `next` branch _must_ have the `main` branch as an ancestor.
-
-### Server
-
-The server is configured by the `git-next-server.toml` file.
-
-#### http
-
-The server needs to be able to receive webhook notifications from your forge,
-(e.g. github.com). You can do this via any method that suits your environment,
-e.g. ngrok or a reverse proxy from a web server that itself can route traffic
-to the machine you are running the git-next server on.
-
-Specify the address and port the server should listen to for incoming webhooks.
-This is the address and port that your reverse proxy should route traffic to.
-
-- **addr** - the IP address the server should bind to
-- **port** - the IP port the server should bind to
-
-#### webhook
-
-Your forges need to know where they should route webhooks to. This should be
-an address this is accessible to the forge. So, for github.com, it would need
-to be a publicly accessible HTTPS URL. For a self-hosted forge, e.g. ForgeJo,
-on your own network, then it only needs to be accessible from the server your
-forge is running on.
-
-- **url** - the HTTPS URL for forges to send webhook to
-
-#### storage
-
-`git-next` will create a bare clone of each repo that you configure it to
-monitor. They will all be created in the directory specified here. This data
-does not need to be backed up, as any missing information will be cloned when
-the server starts up.
-
-- **path** - directory to store local copies of monitored repos
-
-#### forge
-
-Within the forge tree, specify each forge you want to monitor repos on.
-
-Give your forge an alias, e.g. `default`, `gh`, `github`.
-
-e.g.
-
-```toml
-[forge.github]
-forge_type = "GitHub"
-hostname = "github.com"
-user = "username"
-token = "api-key"
-```
-
-- **forge_type** - one of: `ForgeJo` or `GitHub`
-- **hostname** - the hostname for the forge.
-- **user** - the user to authenticate as
-- **token** - application token for the user. See below for the permissions
-  required for on each forge.
-
-Generally, the `user` will need to be able to push to `main` and to _force-push_
-to `next`.
-
-#### repos
-
-For each forge, you need to specify which repos on the forge you want to
-monitor. They do not need to be owned by the `user`, but they `user` must have
-the `push` and `force-push` permissions as mentioned above for each of the
-repositories.
-
-e.g.
-
-```toml
-[forge.github.repos]
-my-repo = { repo = "owner/repo", branch = "main", gitdir = "/home/pcampbell/project/my-repo" }
-
-[forge.github.repos.other-repo]
-repo = "user/other"
-branch = "master"
-main = "master"
-next = "ci-testing"
-dev = "trunk"
-```
-
-Note that toml allows specifying the values on one line, or across multiple
-lines. Both are equivalent. What is not equivalent between `my-repo` and
-`other-repo`, is that one will require a configuration file within the repo
-itself. `other-repo` specifies the `main`, `next` and `dev` branches to be
-used, but `my-repo` doesn't.
-
-A sample `.git-next-toml` file that would need to exist in `my-repo`'s `owner/repo`
-repo, on the `main` branch:
-
-```toml
-[branches]
-main = "main"
-next = "next"
-dev = "dev"
-```
-
-- **repo** - the owner and name of the repo to be monitored
-- **branch** - the branch to look for a `.git-next.toml` file if needed
-- **gitdir** - (optional) you can use a local copy of the repo
-- **main** - the branch to use as `main`
-- **next** - the branch to use as `next`
-- **dev** - the branch to use as `dev`
-
-##### gitdir
-
-Additional notes on using `gitdir`:
-
-When you specify the `gitdir` value, the repo cloned in that directory will
-be used for perform the equivalent of `git fetch`, `git push` and `git push
---force-with-lease`.
-
-These commands will not affect the contents of your working tree, nor will
-it change any local branches. Only the details about branches on the remote
-forge will be updated.
-
-Currently `git-next` can only use a `gitdir` if the forge and repo is the
-same one specified as the `origin` remote. Otherwise the behaviour is
-untested and undefined.
-
-## Behaviour
-
-Development happens on the `dev` branch, where each commit is expected to
-be able to pass the CI checks.
-
-(Note: in the diagrams, mermaid isn't capable of showing `main` and `next` on
-the same commit, so we show `next` as empty)
-
-```mermaid
-gitGraph
-    commit
-    commit
-
-    branch next
-
-    branch dev
-    commit
-    commit
-    commit
-```
-
-When the `git-next` server sees that the `dev` branch is ahead of the `next`
-branch, it will push the `next` branch fast-forward one commit along the `dev`
-branch.
-
-```mermaid
-gitGraph
-    commit
-    commit
-
-    branch next
-    commit
-
-    branch dev
-    commit
-    commit
-```
-
-It will then wait for the CI checks to pass for the newly updated `next` branch.
-When the CI checks for the `next` branch pass, it will push the `main` branch
-fast-forward to the `next` branch. We return to the top and start again.
-
-```mermaid
-gitGraph
-    commit
-    commit
-    commit
-
-    branch next
-
-    branch dev
-    commit
-    commit
-```
-
-If the CI checks should fail for the `next` branch, the developer should
-**amend** that commit **in the history of their `dev` branch**.
-They should then force-push their rebased `dev` branch.
-
-```mermaid
-gitGraph
-    commit
-    commit
-
-    branch next
-    commit
-
-    checkout main
-
-    branch dev
-    commit
-
-    commit
-    commit
-```
-
-`git-next` will then detect that the `next` branch is no longer part of the
-`dev` branch ancestory, and will reset `next` back to `main`.
-We then return to the top, where `git-next` sees that `dev` is ahead of `next`.
-
-When the `dev` branch is on the same commit as the `main` branch, then there
-are no pending commits and `git-next` will wait until it receives a webhook
-indicating that there has been a push to one of the branches. At which point
-it will start at the top again.
-
-### Important
-
-The `dev` branch _should_ have the `next` branch as an ancestor.
-
-However, when the commit on tip of the `next` branch has failed CI and is
-amended, this will not be the case. When this happens `git-next` will
-**force-push** the `next` branch back to the same commit as the `main` branch.
-
-This is the only time a force-push will happen in `git-next`.
-
-In short, the `next` branch **belongs** to `git-next`. Don't try to update it
-yourself. `git-next` will update the `next` it as it sees fit.
-
-## Getting Started
-
-To use `git-next` for trunk-based development, follow these steps:
-
-### Initialise the repo (optional)
-
-You need to specify which branches you are using. You can do this in the repo,
-or in the server configuration.
-
-To create a default config file for the repo, run this command in the root of
-your repo:
-
-```shell
-git next init
-```
-
-This will create a `.git-next.toml` file. [Default](./default.toml)
-
-By default the expected branches are `main`, `next` and `dev`. Each of these
-three branches _must_ exist in your repo.
-
-### Initialise the server
-
-The server uses the file `git-next-server.toml` for configuration. It expects
-to find this file the the current directory when executed.
-
-The create the default config file, run this command:
-
-```shell
-git next server init
-```
-
-This will create a `git-next-server.toml` file. [Default](./server-default.toml)
-
-Edit this file to your needs. See the [Configuration](#configuration) section above.
-
-### Run the server
-
-In the directory with your `git-next-server.toml` file, run the command:
-
-```shell
-git next server start
-```
-
-### Forges
-
-The following forges are supported:
-
-- [ForgeJo](https://forgejo.org) (probably compatible with Gitea, but not tested)
-- [GitHub](https://github.com/)
-
-Note: ForgeJo is a hard fork of Gitea, but currently they are largely compatible.
-For now using a `forge_type` of `ForgeJo` with a Gitea instance will probably work
-okay. The only API calls we make are around registering and unregistering webhooks.
-So, as long as those APIs remain the same, they should be compatible.
-
-#### ForgeJo
-
-Configure the forge in `git-next-server.toml` like:
-
-```toml
-[forge.jo]
-forge_type = "ForgeJo"
-hostname = "git.myforgejo.com"
-user = "bob"
-token = "..."
-
-[forge.jo.repos]
-hello = { repo = "user/hello", branch = "main", gitdir = "/opt/git/projects/user/hello.git" }             # maps to https://git.example.net/user/hello on the branch 'main'
-world = { repo = "user/world", branch = "master", main = "master", next = "upcoming", "dev" = "develop" } # maps to the 'master' branch
-```
-
-The token is created on your ForgeJo instance at (for example)
-`https://git.myforgejo.com/user/settings/applications`
-and requires the `write:repository` permission.
-
-#### GitHub
-
-Configure the forge in `git-next-server.toml` like:
-
-```toml
-[forge.gh]
-forge_type = "GitHub"
-hostname = "github.com" # required even for GitHub
-user = "bob"
-token = "..."
-
-[forge.gh.repos]
-hello = { repo = "user/hello", branch = "main", gitdir = "/opt/git/projects/user/hello.git" }             # maps to https://github.com/user/hello on the branch 'main'
-world = { repo = "user/world", branch = "master", main = "master", next = "upcoming", "dev" = "develop" } # maps to the 'master' branch
-```
-
-The token is created [here](https://github.com/settings/tokens/new) and requires the `repo` and `admin:repo_hook` permissions.

+
+## Trunk-based developement manager.
+
+> A source-control branching model, where developers collaborate on code in a single branch
+> called ‘trunk’, resist any pressure to create other long-lived development branches by
+> employing documented techniques. They therefore avoid merge hell, do not break the build,
+> and live happily ever after. - [source](https://trunkbaseddevelopment.com)
+
+- Status: **BETA** - dog-fooding
+
+`git-next` is a combined server and command-line tool that enables trunk-based
+development workflows where each commit must pass CI before being included in
+the main branch.
+
+## Features
+
+- Allows enforcing the requirement for each commit to pass the CI pipeline before being
+  included in the main branch
+- Provides a server component that manages the trunk-based development process
+- Ensure a consistent, high-quality codebase by preventing untested changes
+  from being added to main
+- Requires each commit uses conventional commit format.
+
+See [Behaviour](#behaviour) to learn how we do this.
+
+## Prerequisits
+
+- Rust 1.76.0 or later - https://www.rust-lang.org
+- pgk-config
+- libssl-dev
+- libdbus-1-dev (ubuntu/debian)
+- dbus-devel (fedora)
+
+See `.cargo/config.toml` for how they are configured.
+
+## Installation
+
+You can install `git-next` from <https://crates.io/>:
+
+```shell
+cargo install git-next
+```
+
+If you use [mise](https://mise.jdx.dev):
+
+```shell
+mise use -g cargo:git-next
+```
+
+Or you can install `git-next` from source after cloning:
+
+```shell
+cargo install --path crates/cli
+```
+
+## Roadmap
+
+- [x] cli
+- [x] server
+- [x] notifications - notify user when intervention required (e.g. to rebase)
+- [x] tui overview
+- [ ] webui overview
+
+## Branch Names
+
+`git-next` uses three branches, `main`, `next` and `dev`, although they do not
+need to have those names. In the documentation we will use those names, but
+each repo must specify the names of the branches to use for each, even if they
+happen to have those same names.
+
+## Configuration
+
+- The branches to use for `main`, `next` and `dev` must be specified in either
+  the `.git-next.toml` in the repo itself, or in the server configuration file,
+  `git-next-server.toml`. See below for details.
+- CI checks should be configured to run when the `next` branch is `pushed`.
+- The `dev` branch _must_ have the `main` branch as an ancestor.
+- The `next` branch _must_ have the `main` branch as an ancestor.
+
+### Server
+
+The server is configured by the `git-next-server.toml` file.
+
+#### listen
+
+The server should listen for webhook notifications from each forge.
+
+```toml
+[listen]
+http = { addr = "0.0.0.0", port = 8080 }
+url = "https://localhost:8080"
+```
+
+##### http
+
+The server needs to be able to receive webhook notifications from your forge,
+(e.g. github.com). You can do this via any method that suits your environment,
+e.g. ngrok or a reverse proxy from a web server that itself can route traffic
+to the machine you are running the git-next server on.
+
+Specify the address and port the server should listen to for incoming webhooks.
+This is the address and port that your reverse proxy should route traffic to.
+
+- **addr** - the IP address the server should bind to
+- **port** - the IP port the server should bind to
+
+##### url
+
+The HTTPS URL for forges to send webhooks to.
+
+Your forges need to know where they should route webhooks to. This should be
+an address this is accessible to the forge. So, for github.com, it would need
+to be a publicly accessible HTTPS URL. For a self-hosted forge, e.g. ForgeJo,
+on your own network, then it only needs to be accessible from the server your
+forge is running on.
+
+#### shout
+
+The server should be able to notify the user when manual intervention is required.
+
+```toml
+[shout]
+desktop = true
+
+[shout.webhook]
+url = "https//localhost:9090"
+secret = "secret-password"
+
+[shout.email]
+from = "git-next@example.com"
+to = "developer@example.com"
+
+[shout.email.smtp]
+hostname = "smtp.example.com"
+username = "git-next@example.com"
+password = "MySecretEmailPassword42"
+```
+
+##### desktop
+
+When specified as `true`, desktop notifications will be sent for some events.
+
+##### webhook
+
+Will send a POST request for some events.
+
+- **url** - the URL to POST the notification to and the
+- **secret** - the sync key used to sign the webhook payload
+
+See [Notifications](#notifications) for more details.
+
+##### email
+
+Will send an email for some events.
+
+- **from** - the email address to send the email from
+- **to** - the email address to send the email to
+
+With just `from` and `to` specified, `git-next` will attempt to send emails
+with `sendmail` if it is configured.
+
+Alternativly, you can use an SMTP relay.
+
+###### smtp
+
+Will send emails using an SMTP relay.
+
+- **hostname** - the SMTP relay server
+- **username** - the account to authenticate as
+- **password** - the password to authenticate with
+
+#### storage
+
+```toml
+[storage]
+path = "./data"
+```
+
+`git-next` will create a bare clone of each repo that you configure it to
+monitor. They will all be created in the directory specified here. This data
+does not need to be backed up, as any missing information will be cloned when
+the server starts up.
+
+- **path** - directory to store local copies of monitored repos
+
+#### forge
+
+Within the forge tree, specify each forge you want to monitor repos on.
+
+Give your forge an alias, e.g. `default`, `gh`, `github`.
+
+e.g.
+
+```toml
+[forge.github]
+forge_type = "GitHub"
+hostname = "github.com"
+user = "username"
+token = "api-key"
+max_dev_commits = 25
+```
+
+- **forge_type** - one of: `ForgeJo` or `GitHub`
+- **hostname** - the hostname for the forge.
+- **user** - the user to authenticate as
+- **token** - application token for the user. See [Forges](#forges) below for the permissions required for each forge.
+- **max_dev_commits** - [optional] the maximum number of commits allowed between `dev` and `main`. Defaults to 25.
+
+Generally, the `user` will need to be able to push to `main` and to _force-push_
+to `next`.
+
+#### repos
+
+For each forge, you need to specify which repos on the forge you want to
+monitor. They do not need to be owned by the `user`, but they `user` must have
+the `push` and `force-push` permissions as mentioned above for each of the
+repositories.
+
+e.g.
+
+```toml
+[forge.github.repos]
+my-repo = { repo = "owner/repo", branch = "main", gitdir = "/home/pcampbell/project/my-repo" }
+
+[forge.github.repos.other-repo]
+repo = "user/other"
+branch = "master"
+main = "master"
+next = "ci-testing"
+dev = "trunk"
+```
+
+Note that toml allows specifying the values on one line, or across multiple
+lines. Both are equivalent. What is not equivalent between `my-repo` and
+`other-repo`, is that one will require a configuration file within the repo
+itself. `other-repo` specifies the `main`, `next` and `dev` branches to be
+used, but `my-repo` doesn't.
+
+A sample `.git-next-toml` file that would need to exist in `my-repo`'s `owner/repo`
+repo, on the `main` branch:
+
+```toml
+[branches]
+main = "main"
+next = "next"
+dev = "dev"
+```
+
+- **repo** - the owner and name of the repo to be monitored
+- **branch** - the branch to look for a `.git-next.toml` file if needed
+- **gitdir** - (optional) you can use a local copy of the repo
+- **main** - the branch to use as `main`
+- **next** - the branch to use as `next`
+- **dev** - the branch to use as `dev`
+
+##### gitdir
+
+Additional notes on using `gitdir`:
+
+When you specify the `gitdir` value, the repo cloned in that directory will
+be used for perform the equivalent of `git fetch`, `git push` and `git push
+--force-with-lease`.
+
+These commands will not affect the contents of your working tree, nor will
+it change any local branches. Only the details about branches on the remote
+forge will be updated.
+
+Currently `git-next` can only use a `gitdir` if the forge and repo is the
+same one specified as the `origin` remote. Otherwise the behaviour is
+untested and undefined.
+
+## Webhook Notifications
+
+When sending a Webhook Notification to a user they are sent using the

+### Events
+
+#### Dev Not Based on Main
+
+This message `type` indicates that the `dev` branch is not based on `main`.
+
+**Action Required**: Rebase the `dev` branch onto the `main` branch.
+
+Sample payload:
+
+```json
+{
+  "data": {
+    "branches": {
+      "dev": "dev",
+      "main": "main"
+    },
+    "forge_alias": "jo",
+    "repo_alias": "kxio",
+    "log": [
+      "* 9bfce91 (origin/dev) fix: add log graph to notifications",
+      "| * c37bd2c (origin/next, origin/main) feat: add log graph to notifications",
+      "|/",
+      "* 8c19680 refactor: macros use a more common syntax"
+    ]
+  },
+  "timestamp": "1721760933",
+  "type": "branch.dev.not-on-main"
+}
+```
+
+#### CI Check Failed
+
+This message `type` indicates that the commit on the tip of the `next` branch has failed the
+configured CI checks.
+
+**Action Required**: Either update the commit to correct the issue CI raised, or, if the issue
+is transient (e.g. a network issue), re-run/re-start the job in your CI.
+
+Sample payload:
+
+```json
+{
+  "data": {
+    "commit": {
+      "sha": "c37bd2caf6825f9770d725a681e5cfc09d7fd4f2",
+      "message": "feat: add log graph to notifications (1 of 2)"
+    },
+    "forge_alias": "jo",
+    "repo_alias": "kxio",
+    "log": [
+      "* 9bfce91 (origin/dev) feat: add log graph to notifications (2 of 2)",
+      "* c37bd2c (origin/next) feat: add log graph to notifications (1 of 2)",
+      "* 8c19680 (origin/main) refactor: macros use a more common syntax"
+    ]
+  },
+  "timestamp": "1721760933",
+  "type": "cicheck.failed"
+}
+```
+
+#### Repo Config Load Failed
+
+This message `type` indicates that `git-next` wasn't able to load the configuration for the
+repo from the `git-next.toml` file in the repository.
+
+**Action Required**: Review the `reason` provided.
+
+Sample payload:
+
+```json
+{
+  "data": {
+    "reason": "File not found: .git-next.toml",
+    "forge_alias": "jo",
+    "repo_alias": "kxio"
+  },
+  "timestamp": "1721760933",
+  "type": "config.load.failed"
+}
+```
+
+#### Webhook Registration Failed
+
+This message `type` indicates that `git-next` wasn't able to register it's webhook with the
+forge repository, so will not receive updates when the branches in the repo are updated.
+
+**Action Required**: Review the `reason` provided.
+
+Sample payload:
+
+```json
+{
+  "data": {
+    "reason": "repo config not loaded",
+    "forge_alias": "jo",
+    "repo_alias": "kxio"
+  },
+  "timestamp": "1721760933",
+  "type": "webhook.registration.failed"
+}
+```
+
+## Behaviour
+
+The branch names are configurable, but we will talk about `main`, `next` and `dev`.
+
+Development happens on the `dev` branch, where each commit is expected to
+be able to pass the CI checks.
+
+(Note: in the diagrams, mermaid isn't capable of showing `main` and `next` on
+the same commit, so we show `next` as empty)
+
+```mermaid
+gitGraph
+    commit
+    commit
+
+    branch next
+
+    branch dev
+    commit
+    commit
+    commit
+```
+
+When the `git-next` server sees that the `dev` branch is ahead of the `next`
+branch, it will push the `next` branch fast-forward one commit along the `dev`
+branch.
+
+```mermaid
+gitGraph
+    commit
+    commit
+
+    branch next
+    commit
+
+    branch dev
+    commit
+    commit
+```
+
+It will then wait for the CI checks to pass for the newly updated `next` branch.
+When the CI checks for the `next` branch pass, it will push the `main` branch
+fast-forward to the `next` branch. We return to the top and start again.
+
+```mermaid
+gitGraph
+    commit
+    commit
+    commit
+
+    branch next
+
+    branch dev
+    commit
+    commit
+```
+
+If the CI checks should fail for the `next` branch, the developer should
+**amend** that commit **in the history of their `dev` branch**.
+They should then force-push their rebased `dev` branch.
+
+```mermaid
+gitGraph
+    commit
+    commit
+
+    branch next
+    commit
+
+    checkout main
+
+    branch dev
+    commit
+
+    commit
+    commit
+```
+
+`git-next` will then detect that the `next` branch is no longer part of the
+`dev` branch ancestory, and will reset `next` back to `main`.
+We then return to the top, where `git-next` sees that `dev` is ahead of `next`.
+
+When the `dev` branch is on the same commit as the `main` branch, then there
+are no pending commits and `git-next` will wait until it receives a webhook
+indicating that there has been a push to one of the branches. At which point
+it will start at the top again.
+
+### Important
+
+The `dev` branch _should_ have the `next` branch as an ancestor.
+
+However, when the commit on tip of the `next` branch has failed CI and is
+amended, this will not be the case. When this happens `git-next` will
+**force-push** the `next` branch back to the same commit as the `main` branch.
+
+This is the only time a force-push will happen in `git-next`.
+
+In short, the `next` branch **belongs** to `git-next`. Don't try to update it
+yourself. `git-next` will update the `next` it as it sees fit.
+
+## Getting Started
+
+To use `git-next` for trunk-based development, follow these steps:
+
+### Initialise the repo (optional)
+
+You need to specify which branches you are using. You can do this in the repo,
+or in the server configuration.
+
+To create a default config file for the repo, run this command in the root of
+your repo:
+
+```shell
+git next init
+```
+
+This will create a `.git-next.toml` file. [Default](./crates/cli/default.toml)
+
+By default the expected branches are `main`, `next` and `dev`. Each of these
+three branches _must_ exist in your repo.
+
+### Initialise the server
+
+The server uses the file `git-next-server.toml` for configuration. It expects
+to find this file the the current directory when executed.
+
+The create the default config file, run this command:
+
+```shell
+git next server init
+```
+
+This will create a `git-next-server.toml` file. [Default](./crates/server/server-default.toml)
+
+Edit this file to your needs. See the [Configuration](#configuration) section above.
+
+### Run the server
+
+In the directory with your `git-next-server.toml` file, run the command:
+
+```shell
+git next server start
+```
+
+### Forges
+
+The following forges are supported:
+
+- [ForgeJo](https://forgejo.org) (probably compatible with Gitea, but not tested)
+- [GitHub](https://github.com/)
+
+Note: ForgeJo is a hard fork of Gitea, but currently they are largely compatible.
+For now using a `forge_type` of `ForgeJo` with a Gitea instance will probably work
+okay. The only API calls we make are around registering and unregistering webhooks.
+So, as long as those APIs remain the same, they should be compatible.
+
+#### ForgeJo
+
+Configure the forge in `git-next-server.toml` like:
+
+```toml
+[forge.jo]
+forge_type = "ForgeJo"
+hostname = "git.myforgejo.com"
+user = "bob"
+token = "..."
+
+[forge.jo.repos]
+hello = { repo = "user/hello", branch = "main", gitdir = "/opt/git/projects/user/hello.git" }             # maps to https://git.example.net/user/hello on the branch 'main'
+world = { repo = "user/world", branch = "master", main = "master", next = "upcoming", "dev" = "develop" } # maps to the 'master' branch
+```
+
+The token is created on your ForgeJo instance at (for example)
+`https://git.myforgejo.com/user/settings/applications`
+and requires the `write:repository` permission.
+
+#### GitHub
+
+Configure the forge in `git-next-server.toml` like:
+
+```toml
+[forge.gh]
+forge_type = "GitHub"
+hostname = "github.com" # required even for GitHub
+user = "bob"
+token = "..."
+
+[forge.gh.repos]
+hello = { repo = "user/hello", branch = "main", gitdir = "/opt/git/projects/user/hello.git" }             # maps to https://github.com/user/hello on the branch 'main'
+world = { repo = "user/world", branch = "master", main = "master", next = "upcoming", "dev" = "develop" } # maps to the 'master' branch
+```
+
+The token is created [here](https://github.com/settings/tokens/new) and requires the `repo` and `admin:repo_hook` permissions.
+
+## Docker
+
+`git-next` is available as a [Docker image](https://git.kemitix.net/kemitix/-/packages/container/git-next/).
+
+```shell
+docker pull docker pull git.kemitix.net/kemitix/git-next:latest
+```
+
+### Docker Compose
+
+Here is an example `docker-compose.yml`:
+
+```yaml
+services:
+  server:
+    image: git.kemitix.net/kemitix/git-next:latest
+    container_name: git-next-server
+    restart: unless-stopped
+    environment:
+      RUST_LOG: "hyper=warn,info"
+    ports:
+      - 8080:8092
+    volumes:
+      - ./:/app/
+```
+
+Note: this assumes the `git-next-server.toml` has a `listen.http.port` of
+`8092` and that you are using a reverse proxy to route traffic arriving at
+`listen.url` to port `8080`.
+
+### Docker Run
+
+This will run with the `server start` options:
+
+```shell
+docker run -it -p "8080:8092" -v .:/app/ git.kemitix.net/kemitix/git-next:latest
+```
+
+To perform `server init`:
+
+```shell
+docker run -it -v .:/app/ git.kemitix.net/kemitix/git-next:latest server init
+```
+
+To perform repo `init`:
+
+```shell
+docker run -it -v .:/app/ git.kemitix.net/kemitix/git-next:latest init
+```
+
+TUI support is not available in the docker container. See [kemitix/git-next#154](https://git.kemitix.net/kemitix/git-next/issues/154).

+# Terminal UI
+
+Currently the Terminal UI is an experimental feature, controlled by the feature flag `tui`.
+
+## Build & Run
+
+The build `git-next` with the Terminal UI use: `cargo install git-next --features tui`
+
+To run `git-next` with the Terminal UI use: `git-next server start --ui`
+
+### Docker
+
+If using the docker image you will need to create a directory to mount that contains the
+`git-next-server.toml` file. Mount this directory as `/app`. In the example below we use
+the current directory for this.
+
+If you want to persist the clones of your monitored repos then point `storage.path` in
+`git-next-server.toml` to the the directory `/app`, (e.g. `path = "/app/data"`).
+
+Map the port your webhook notifications are arriving on to the port specified in `listen.http.port`.
+
+`docker run -it -p "8080:8092" -v .:/app/ git.kemitix.net/kemitix/git-next:latest server start --ui`
+
+## logs
+
+When the Terminal UI is enabled via the `--ui` parameter, logs are written to the file:
+
+- `???` on Linux
+- `~/Library/Application Support/net.kemitix.git-next/git-next.log` on MacOS
+- `???` on Windows
+
+## Keys
+
+- `q` - Quit
+- `j` - Down
+- `k` - Up
+- `f` - Page Down
+- `b` - Page Up
+- `g` - Top/Home
+- `G` - Bottom/End
