+Pub.dev lister
+==============
+
+The Pubdev lister list origins from `pub.dev`_, the `Dart`_ and `Flutter`_ packages registry.
+
+The registry provide an `http api`_ from where the lister retrieve package names.
+
+As of August 2022 `pub.dev`_ list 33535 package names.
+
+Origins retrieving strategy
+---------------------------
+
+To get a list of all package names we call `https://pub.dev/api/packages` endpoint.
+There is no other way for discovery (no archive index, no database dump, no dvcs repository).
+
+Page listing
+------------
+
+There is only one page that list all origins url based
+on `https://pub.dev/api/packages/{pkgname}`.
+The origin url corresponds to the http api endpoint that returns complete information
+about the package versions (name, version, author, description, release date).
+
+Origins from page
+-----------------
+
+The lister yields all origins url from one page.
+
+Running tests
+-------------
+
+Activate the virtualenv and run from within swh-lister directory::
+
+   pytest -s -vv --log-cli-level=DEBUG swh/lister/pubdev/tests
+
+Testing with Docker
+-------------------
+
+Change directory to swh/docker then launch the docker environment::
+
+   docker-compose up -d
+
+Then connect to the lister::
+
+   docker exec -it docker_swh-lister_1 bash
+
+And run the lister (The output of this listing results in “oneshot” tasks in the scheduler)::
+
+   swh lister run -l pubdev
+
+.. _pub.dev: https://pub.dev
+.. _Dart: https://dart.dev
+.. _Flutter: https://flutter.dev
+.. _http api: https://pub.dev/help/api
