 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 -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).
