-## Getting started
-
-To navigate our codebase with confidence, see [the introduction to working in the docs repository](/contributing/working-in-docs-repository.md) :confetti_ball:. For more information on how we write our markdown files, see [the GitHub Markdown reference](contributing/content-markup-reference.md).
-
-Check to see what [types of contributions](/contributing/types-of-contributions.md) we accept before making changes. Some of them don't even require writing a single line of code :sparkles:.

+## Repository Settings
 
-The process is very simple.
-- Fork the project into your account.
-- Clone your fork.
-- Add an upstream remote: `git remote add upstream git@github.com:juju/python-libjuju.git`
-- Check with `git remote -v`, origin should point to your fork, upstream should point to ours.
-- If your changes are going to be on top of a specific branch (e.g., `2.9`), then fetch and switch to that.
-- `git switch -c your-branch-name`
-- Make sure that you have run `pre-commit install`
-- Make your changes, create your commits.
-- `git push -u origin your-branch-name`
+- Commit titles have to follow https://www.conventionalcommits.org/.
+- Commits have to be signed, see [GitHub advice](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits); you can [use your SSH key](https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification#ssh-commit-signature-verification).
+- For Warthogs, CLA is assumed when commits are authored with your `@canonical.com` email.
+- For others, please sign the CLA at https://launchpad.net/ and read [further details](https://ubuntu.com/legal/contributors/faq) here.
 
-And that's it, just follow the link that Git will produce. We kindly ask you to follow our PR template (at least keep the sections there), so it can be faster for us to review and move it forward.
+## Bot Commands
 
-There are a few project specific things you may need to take care of so that your PR passes the automated testing.
-  - Check that all your [commits are signed](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits).
-  - Use [Conventional Commits](https://github.com/juju/juju/blob/main/doc/CONTRIBUTING.md#conventional-commits) for commit messages, following the Juju project's [conventional commit types](https://github.com/juju/juju/blob/main/doc/conventional-commits.md).
-  - Please [sign the CLA](#contributor-licence-agreement) if you haven't already.

-#### What's next
-
-So when you create the PR, a bot might spam some messages there for admins to review the PR. Don't panic, everything's good. Someone from our team needs to push a button to allow for the CI to run.
-
-Some time after we see the tests are passing, someone from our team will review. Whoever reviews
-it might ask for some changes, or some tests to be fixed, etc. Finally, the PR will be approved, and again,
-someone from our team (probably the reviewer) will comment `/merge`, which triggers the Juju bot to start the merging process, which will automagically complete and merge your PR onto the desired branch. :confetti_ball:
-
-#### Some quick notes:
-
-- Don't forget to [link PR any issues](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue) if you are solving any.
-- Enable the checkbox to [allow maintainer edits](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/allowing-changes-to-a-pull-request-branch-created-from-a-fork) so the branch can be updated for a merge.
-- A `/build` comment will trigger a fresh CI run.
-- If you run into any merge issues, checkout this [git tutorial](https://github.com/skills/resolve-merge-conflicts) to help you resolve merge conflicts and other issues.
