+
+This mod installs code-server/openvscode-server extensions at startup. The list of extensions to be installed should be provided using environment variable `VSCODE_EXTENSION_IDS` separated by `|`.
+
+__NOTE__:
+Since transitioning from `v3.12.0` to `v4.0.x` `code-server` has been forced to use a new Extensions Gallery / Marketplace. This results in a smaller set of plugins being available to install. Please take this into account before opening an Issue! 
+
+A workaround for this is to use the environment variable `EXTENSIONS_GALLERY` to provide a different marketplace URL. The commandline installer used by this plugin will also use the marketplace provided by this variable.
+
+Please refer to the [code-server FAQ](https://github.com/coder/code-server/blob/main/docs/FAQ.md#how-do-i-use-my-own-extensions-marketplace) for additional information.
 
-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 `|`.
 
 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
+  environment:
+    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'
+    ## Optionally use a different marketplace if required extensions are unavailable. e.g.:
+    # EXTENSIONS_GALLERY: '{"serviceUrl": "https://extensions.coder.com/api"}'
+    # EXTENSIONS_GALLERY: '{"serviceUrl": "https://open-vsx.org/vscode/gallery", "itemUrl": "https://open-vsx.org/vscode/item"}'
 ```
