 # Gitea
 
+Gitea is a selfhosted GIT server.
+
 Gitea runner's function exactly the same as GitHub runners. They're just stored in the .gitea folder instead of .github folder.
 
-## Docker
+## GitHub's gh cli
+
+Whenever you need to use the gh cli, use an equivalent tool from the 'rc-gitea' mcp tool instead.
+
+**Example**
+`gh issue list --repo owner/repo` should instead use `list_repo_issues` from rc-gitea mcp
+
+
+## Docker Action Example
 Gitea supports storing docker images.
 
 This is an example of a gitea action that creates and pushes an image.
