 """
-Script used to publish GitHub release notes extracted from CHANGELOG.rst.
+Script used to generate a Markdown file containing only the changelog entries of a specific pytest release, which
+is then published as a GitHub Release during deploy (see workflows/deploy.yml).
 
-This script is meant to be executed after a successful deployment in GitHub actions.
-
-Uses the following environment variables:
-
-* GIT_TAG: the name of the tag of the current commit.
-* GH_RELEASE_NOTES_TOKEN: a personal access token with 'repo' permissions.
-
-  Create one at:
-
-    https://github.com/settings/tokens
-
-  This token should be set in a secret in the repository, which is exposed as an
-  environment variable in the main.yml workflow file.
-
-The script also requires ``pandoc`` to be previously installed in the system.
+The script requires ``pandoc`` to be previously installed in the system -- we need to convert from RST (the format of
+our CHANGELOG) into Markdown (which is required by GitHub Releases).
 
 Requires Python3.6+.
