+---@brief
+--- https://github.com/lttb/gh-actions-language-server
+---
+--- Language server for GitHub Actions.
+---
+--- The projects [forgejo](https://forgejo.org/) and [gitea](https://about.gitea.com/)
+--- design their actions to be as compatible to github as possible
+--- with only [a few differences](https://docs.gitea.com/usage/actions/comparison#unsupported-workflows-syntax) between the systems.
+--- The `gh_actions_ls` is therefore enabled for those `yaml` files as well.
+---
+--- The `gh-actions-language-server` can be installed via `npm`:
+---
+--- ```sh
+--- npm install -g gh-actions-language-server
+--- ```
+
