+Code for the [harlequin.sh](https://harlequin.sh/) website is hosted in the [`harlequin-web`](https://github.com/tconbeer/harlequin-web) repo. The docs are all written in Markdown, which makes them easy to update. Please open PRs against that repo if our docs can be improved.

+## Contributing Code
+
+We aim to create a welcoming and inclusive environment for new contributors, whether this is your first open-source contribution or your 1,000th. Please see the [Contributing Guide](https://harlequin.sh/docs/contributing/index) for detailed instructions on local development and testing, including an end-to-end walkthrough [video](https://www.tella.tv/video/cls3nmne700000gl4bcp91arr/view).

-### Setting up Your Dev Environment and Running Tests
-
-1. Install Poetry v1.2 or higher if you don't have it already. You may also need or want pyenv, make, and gcc.
-1. Fork this repo, and then clone the fork into a directory (let's call it `harlequin`), then `cd harlequin`.
-1. Use `poetry install --sync` to install the project (editable) and its dependencies (including all test and dev dependencies) into a new virtual env.
-1. Use `poetry shell` to spawn a subshell.
-1. Type `make` to run all tests and linters, or run `pytest`, `black .`, `ruff . --fix`, and `mypy` individually.

-### Opening PRs
+Thanks for your interest in Harlequin! Harlequin is primarily maintained by [Ted Conbeer](https://github.com/tconbeer), but he welcomes all contributions!
 
-1. PRs should be motivated by an open issue. If there isn't already an issue describing the feature or bug, [open one](https://github.com/tconbeer/harlequin/issues/new). Do this before you write code, so you don't waste time on something that won't get merged.
-2. Ideally new features and bug fixes would be tested, to prevent future regressions. Textual provides a test harness that we use to test features of Harlequin. You can find some examples in the `tests` directory of this project. Please include a test in your PR, but if you can't figure it out, open a PR to ask for help.
-2. Open a PR from your fork to the `main` branch of `tconbeer/harlequin`. In the PR description, link to the open issue, and then write a few sentences about **why** you wrote the code you did: explain your design, etc.
-3. Ted may ask you to make changes, or he may make them for you. Don't take this the wrong way -- he values your contributions, but he knows this isn't your job, either, so if it's faster for him, he may push a commit to your branch or create a new branch from your commits.
