-# Rsync - Docker mod for openssh-server
+# Extension Arguments - Docker mod for code-server
 
-This mod adds rsync to openssh-server, to be installed/updated during container start.
+This mod installs code-server extensions at startup. The list of extensions to be installed should be provided using environment variable `VSCODE_EXTENSION_IDS` separated by `|`.
 
-In openssh-server docker arguments, set an environment variable `DOCKER_MODS=linuxserver/mods:openssh-server-rsync`
-
-If adding multiple mods, enter them in an array separated by `|`, such as `DOCKER_MODS=linuxserver/mods:openssh-server-rsync|linuxserver/mods:openssh-server-mod2`
-
-# Mod creation instructions
-
-* Fork the repo, create a new branch based on the branch `template`.
-* Edit the `Dockerfile` for the mod. `Dockerfile.complex` is only an example and included for reference; it should be deleted when done.
-* Inspect the `root` folder contents. Edit, add and remove as necessary.
-* Edit this readme with pertinent info, delete these instructions.
-* Finally edit the `.github/workflows/BuildImage.yml`. Customize the build branch, and the vars for `BASEIMAGE` and `MODNAME`.
-* Ask the team to create a new branch named `<baseimagename>-<modname>`. Baseimage should be the name of the image the mod will be applied to. The new branch will be based on the `template` branch.
-* Submit PR against the branch created by the team.
+For example, to install the `vscode-docker` and `vscode-icons` extensions add the following lines to your docker compose service:
+```yaml
+- DOCKER_MODS=linuxserver/mods:code-server-docker|linuxserver/mods:code-server-extension-arguments
+- VSCODE_EXTENSION_IDS=vscode-icons-team.vscode-icons|ms-azuretools.vscode-docker
+```
