 No additional configuration is needed in your ``towncrier`` configuration; the hook will read from the appropriate configuration files in your project.

+``towncrier-checks`` Hook
+-------------------------
+
+The ``towncrier-checks`` hook matches the ``towncrier check`` command, useful to check that a feature branch adds at least one news fragment.
+
+This hook runs no matter which files were modified, only during the ``pre-push`` stage by default.
+
+
+``towncrier-draft`` Hook
+------------------------
+
+The ``towncrier-draft`` hook matches the ``towncrier build --draft`` command, useful to create a draft of news fragments that will be added to the next release, ensuring they are formatted correctly.
+
+This hook runs in all stages if any text files were added or modified.
+
+.. note::
 
+    The ``draft`` hook was previously (somewhat confusingly) named ``towncrier-check``.
 
-Usage with custom configuration and directories
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-News fragments are stored in ``changelog.d/`` in the root of the repository and we want to keep the news fragments when running ``update``:
+``towncrier-update`` Hook
+-------------------------
+
+The ``towncrier-update`` hook matches the ``towncrier build`` command, which updates the changelog to a new version containing any news fragments.
+
+It requires the version to be defined in your configuration file, or that is can be inferred from the Python package defined in your configuration file.
+It uses the ``--yes`` flag to automatically confirm the git deletion of news fragments that are added to the changelog.
+
+This hook runs no matter which files were modified, but only via the ``manual`` stage by default (meaning you run ``pre-commit run --hook-stage manual towncrier-update`` to update the changelog, or change the ``stages`` in your pre-commit configuration file).
+
+
+Customizing the hook arguments
+------------------------------
+
+You can customize the hook arguments by adding them to the ``args`` key in your pre-commit configuration file.
