+The `build-project` command will make it possible to use relative package includes.
 This feature is very useful for monorepos and when sharing code between projects.
 
+
+The `check-project` command is useful to check that dependencies are added properly in a project.
+It uses the `MyPy` tool under the hood, and will output any errors from the static type checker.
+
+
 ## Usage
 Navigate to the project folder (where the `pyproject.toml` file is).
+
+Build a project:
 ``` shell
 poetry build-project
 ```
 
+Check the code used in a project:
+
+``` shell
+poetry check-project
+```
+
+Check the code, with a custom `MyPy` configuration to override the defaults:
+
+``` shell
+poetry check-project --config-file <PATH-TO-MYPY.INI-CONFIG-FILE>
+```
+
 ## Installation
 This plugin can be installed according to the official [Poetry docs](https://python-poetry.org/docs/plugins/#using-plugins).
