+## Debugging openstates-core code
+
+### Update command / scrapers
+
+There are
+[instructions on running a scraper here](https://docs.openstates.org/contributing/scrapers/#running-your-first-scraper)
+but what if you want to debug the command that wraps around the scraper code? This
+repository's [update CLI module](openstates/cli/update.py)
+is the code that accepts parameters and actually executes the scraper (from
+[openstates-scrapers](https://github.com/openstates/openstates-scrapers)). Another wrinkle is that the update command
+needs to be run inside the context of the `openstates-scrapers` repository, as it will attempt to load in the relevant
+scraper for the jurisdiction requested, and that import will fail if you try to run the code here
+within `openstates-core`.
+
+Here's a recipe using PyCharm to successfully debug the update command:
+
+#### Requirements to run code natively (not in docker)
+
+* You need the `gdal` library installed on the host system. For me: `sudo apt install gdal-bin python3-gdal`
+* `openstates-core` checked out at /home/username/repo/openstates/openstates-core/
+* (let's assume you have made some changes in `openstates-core` that you want to test)
+* `openstates-scrapers` checked out /home/username/repo/openstates/openstates-scrapers/
+* Change directory to /home/username/repo/openstates/openstates-scrapers/
+* Install required python version using the `pyenv` utility
+* `pip install poetry` (if that python version doesn't already have it)
+
+#### Debugging natively
+
+* If you have previously installed the `openstates` dependency (eg `openstates-core`), then you need
+  to run `poetry remove openstates` to clear that remotely-installed (from pypi) dependency. Each time you make a round
+  of changes to `openstates-core`, you will need to remove and then re-add the dependency.
+* `poetry add ../openstates-core/` will add the `openstates` dependency from your local filesystem/local checkout
+* `poetry install`
+* In PyCharm, open the `openstates-scrapers` folder
+* In PyCharm, set up a new run config:
+    * type: python
+    * module: openstates.cli.update
+    * parameters: vi bills (or whatever you want to run)
+    * working directory: /home/username/repo/openstates/openstates-scrapers/scrapers
+* Run the run config in debug mode within PyCharm (eg the one working on `openstates-scrapers`). You can set
+  breakpoints within both the scraper code AND in the `openstates-core` code. However you need to open (in PyCharm)
+  the copy of `openstates-core` that poetry installed, which probably is in a location like:
+  `/home/username/.cache/pypoetry/virtualenvs/openstates-scrapers-93BMrPXy-py3.9/lib/python3.9/site-packages/openstates/cli/update.py`
+
+**Reminder**: when further changes are made to the `openstates-core` package locally, and you want to debug them again,
+you need to remove/re-add to update files in `openstates-scrapers`
+
+* Change directory to `/home/username/repo/openstates/openstates-scrapers/`
+* `poetry remove openstates`
+* `poetry add ../openstates-core/`
+* (you will need to re-establish breakpoints in any openstates-core files)

 Release Process:
 
-* bump version in pyproject.toml
-* update changelog
-* tag & push tag
-* poetry publish --build
+* bump version in `pyproject.toml`
+* update `CHANGELOG.md`
+* once code is merged into `main`
+  * Create a new Release in Github
+    * Target `main`
+    * Create a new tag that matches new version from `pyproject.toml`
+  * By creating a tag, this triggers the [release workflow](./.github/workflows/release.yml) which builds and
+    pushes the new version to PyPi
