+### Arguments
+Here are some arguments that can be used with `incr`:
+- `-d` : Directory where to search for the version files (default: `.`)
+- `-t` : Tag name pattern, where `%s` will be replaced with the new version (default: `v%s`)
+
+Example:
+```shell
+~> incr npm patch -d ./subprojects/web/ -t MyCustomTagPrefix/%s
+```
+
+This will :
+- Search for `package.json` and `package-lock.json` files inside `./subprojects/web/` and update the patch version
+- Create a tag named `MyCustomTagPrefix/2.3.4`
+- Commit the changes under the message `MyCustomTagPrefix/2.3.4`
