+This is a very simple script to dump the members of the PHP GitHub
+organization in Markdown format.
+
+It requires a GitHub personal access token (classic) with `read:org`
+and `admin:org` privileges.
+
+To run:
+
+```sh
+$ export GITHUB_TOKEN="..."
+$ /local/systems/dump-gh-org/dump-gh-org > out.md
+```
