+# TUI Actor
+
+- Maintains it's own copy of data for holding state
+- Is notified of update via actor messages from the Server and Repo Actors
+- State is somewhat heirarchical
+
+## State
+
+```rust
+enum TuiState {
+ Initial,
+ Configured {
+   app_config: ValidAppConfig,
+   forges: BTreeMap<ForgeAlias, RepoState>,
+ },
+}
+enum RepoState {
+ Identified { repo_alias: RepoAlias },
+ Configured { repo_alias: RepoAlias, branches: RepoBranches },
+ Ready { repo_alias: RepoAlias, branches: RepoBranches, main: Commit, next: Commit, dev: Commit, log: Log },
+ Alert { repo_alias: RepoAlias, message: String, branches: RepoBranches, main: Commit, next: Commit, dev: Commit, log: Log },
+}
+```
+
+## State Transitions:
+
+### `TuiState`
+
+```mermaid
+stateDiagram-v2
+  * --> Initial
+  Initial --> Configured
+```
+
+- `message!(Configure, ValidAppConfig, "Initialise UI with valid config");`
+
+### `RepoState`
+
+```mermaid
+stateDiagram-v2
+  * --> Identified
+  Identified --> Configured
+  Identified --> Ready
+  Configured --> Ready
+  Ready --> Alert
+  Configured --> Alert
+  Identified --> Alert
+  Alert --> Ready
+```
+
+- `Identified` - from AppConfig where a repo alias is listed, but repo config needs to be loaded from `.git-next.toml`
+- `Configured` - as `Identified` but either branches are identified in server config, OR the `.git-next.toml` file has been loaded
+- `Ready` - as `Configured` but the branch positions have been validated and do not require user intervention
+- `Alert` - as `Ready` but user intervention is required
+
+## Widget
+
+Initial mock up of UI. Possibly add some borders and padding as it looks a little squached together.
