+### [cz-path](https://pypi.org/project/cz-path/)
+
+Provides prefix choices for commit messages based on staged files (Git only).
+For example, if the staged files are `component/z/a.ts` and `component/z/b.ts`,
+the path prefix option will be `component/z` and commit message might look like:
+`component/z/: description of changes`. If only one file is staged, the extension
+is removed in the prefix.
+
+#### Installation
+
+```sh
+pip install cz-path
+```
+
+#### Usage
+
+Add `cz-path` to your configuration file.
+
+Example for `.cz.json`:
+
+```json
+{
+  "commitizen": {
+    "name": "cz_path",
+    "remove_path_prefixes": ["src", "module_name"]
+  }
+}
+```
+
+The default value for `remove_path_prefixes` is `["src"]`. Adding `/` to the
+prefixes is not required.
+
+#### Example session
+
+```plain
+ $ git add .vscode/
+ $ cz -n cz_path c
+? Prefix: (Use arrow keys)
+ » .vscode
