+### Custom Config Path
+
+Specify a custom path to the configuration file using the `--config` option
+
+```sh
+commit-and-tag-version --config ./path/to/.versionrc.js
+
+# or using alias
+commit-and-tag-version -c ./path/to/.versionrc.js
+```
+
+All config file formats can be used:
+
+```sh
+commit-and-tag-version -c ./path/to/.versionrc[.js|.cjs|.json]
+```
+
 ### Signing Commits and Tags
 
 If you have your GPG key set up, add the `--sign` or `-s` flag to your `commit-and-tag-version` command.
