 You can even open SSH sessions and WSL distributions from the context menu of `Windows Terminal` in a tab.
 
+==== Window Title
+
+By default git-bash overwrites the window title with `MINGW64:«current-directory»` on every prompt, so all your tabs and windows look alike in the taskbar and in `Alt`+`Tab`.
+IDEasy therefore replaces this with a title that tells you which project, workspace and repository the shell is initialized for:
+
+* `ideasy>«project»>«workspace»>«repository»` when you are inside a repository (e.g. `ideasy>devonfw>main>IDEasy`)
+* `ideasy>«project»>«workspace»` when you are inside a workspace but outside any repository
+* `ideasy>«project»` when you are inside an IDEasy project but outside any workspace
+* `ideasy` when you are outside of any IDEasy project
+
+Workspace and repository are derived from your current directory, so the title also follows a plain `cd` and not only `ide` or `icd`.
+As with `icd -r`, hidden folders are not considered to be repositories, and for a nested repository such as `backend/core` the top-level folder is shown to keep the title short.
+This only applies to git-bash on Windows - on macOS and Linux your prompt configuration is left untouched.
