+# Contributing to Ghostty.org
+
+Ghostty.org is the official Ghostty website.
+
+**Note, Ghostty.org has different contributing guidelines than
+the Ghostty project.** They are simpler. If you are familiar with
+the Ghostty project contributing guidelines, you probably still
+want to read the Quick Guide below.
+
+## Quick Guide
+
+**There is a typo or grammatical error in the website.**
+
+Open a pull request with the correction. No need to make an
+issue or discussion.
+
+**There is a behavioral bug in the website.**
+
+Open an issue with clear steps to reproduce the bug.
+
+**There is a feature request for the website.**
+
+[Open a discussion](https://github.com/ghostty-org/ghostty/discussions)
+in the _Ghostty project_ repository. All feature requests even
+for the website flow through the Ghostty discussions as a central
+point.
+
+New pages or new content constitutes a feature request.
+
+Once the feature request is accepted, it will be converted to
+an issue in this repository.
+
+**Drive-by pull requests for features are discouraged.** If you
+open a PR without previous discussion with a maintainer, you do
+so at your own risk.

 ## Local Development
 
-### via Node (recommended)
+The official development environment is defined by Nix. You do not need
+to use Nix to develop the website, but the Nix environment is the
+only supported development environment.
 
 To spin up a local server, you can simply run `make`.
 
 ```bash
 make
 ```
 
-Open [http://localhost:3000](http://localhost:3000) with your browser to view the website.

-### via Docker
+## Contributing
 
-If you don't have node configured, you can also build the website locally with Docker.
-
-This approach will compile a [production build](https://nextjs.org/docs/pages/building-your-application/deploying#production-builds), which is less ideal for local development.
-
-```bash
-make docker
