+# AI Usage Policy
+
+The Cinny project has strict rules for AI usage:
+
+- **All AI usage in any form must be disclosed.** You must state
+  the tool you used (e.g. Claude Code, Cursor, Amp, Codex) along with
+  the extent that the work was AI-assisted.
+
+- **The human-in-the-loop must fully understand all code.** If you
+  can't explain what your changes do and how they interact with the
+  greater system without the aid of AI tools, do not contribute
+  to this project.
+
+- **Issues and discussions can use AI assistance but must have a full
+  human-in-the-loop.** This means that any content generated with AI
+  must have been reviewed _and edited_ by a human before submission.
+  AI is very good at being overly verbose and including noise that
+  distracts from the main point. Humans must do their research and
+  trim this down.
+
+- **No AI-generated media is allowed (art, images, videos, audio, etc.).**
+  Text and code are the only acceptable AI-generated content, per the
+  other rules in this policy.
+
+- **Bad AI drivers will be banned.** You've been warned. We love to
+  help junior developers learn and grow, but if you're interested
+  in that then don't use AI, and we'll help you.
+
+These rules apply only to outside contributions to Cinny. Maintainers
+are exempt from these rules and may use AI tools at their discretion;
+they've proven themselves trustworthy to apply good judgment.
+
+## There are Humans Here
+
+Please remember that Cinny is maintained by humans.
+
+Every discussion, issue, and pull request is read and reviewed by
+humans (and sometimes machines, too). It is a boundary point at which
+people interact with each other and the work done. It is rude and
+disrespectful to approach this boundary with low-effort, unqualified
+work, since it puts the burden of validation on the maintainer.
+
+In a perfect world, AI would produce high-quality, accurate work
+every time. But today, that reality depends on the driver of the AI.
+And today, most drivers of AI are just not good enough. So, until either
+the people get better, the AI gets better, or both, we have to have
+strict rules to protect maintainers.
+
+## AI is Welcome Here
+
+**Our reason for the strict AI policy is not due to an anti-AI stance**, but
+instead due to the number of highly unqualified people using AI. It's the
+people, not the tools, that are the problem.
+
+I include this section to be transparent about the project's usage about
+AI for people who may disagree with it, and to address the misconception
+that this policy is anti-AI in nature.

-## Bug reports
+## The Critical Rule
 
-Bug reports and feature suggestions must use descriptive and concise titles and be submitted to [GitHub Issues](https://github.com/ajbura/cinny/issues). Please use the search function to make sure that you are not submitting duplicates, and that a similar report or request has not already been resolved or rejected.
+**The most important rule: you must understand your code.** If you can't
+explain what your changes do and how they interact with the greater system
+without the aid of AI tools, do not contribute to this project.
 
-## Pull requests
+Using AI to write code is fine. You can gain understanding by interrogating an
+agent with access to the codebase until you grasp all edge cases and effects
+of your changes. What's not fine is submitting agent-generated slop without
+that understanding. Be sure to read the [AI Usage Policy](AI_POLICY.md).

-**NOTE: If you want to add new features, please discuss with maintainers before coding or opening a pull request.** This is to ensure that we are on same track and following our roadmap.
+[All issues are actionable](#issues-are-actionable). Pick one and start
+working on it. Thank you. If you need help or guidance, comment on the issue.
+Issues that are extra friendly to new contributors are tagged with
+["contributor friendly"].
 
-**Please use clean, concise titles for your pull requests.** We use commit squashing, so the final commit in the dev branch will carry the title of the pull request. For easier sorting in changelog, start your pull request titles using one of the verbs "Add", "Change", "Remove", or "Fix" (present tense).

-Example:
+### I have a bug! / Something isn't working
 
-|Not ideal|Better|

-|Fixed markAllAsRead in RoomTimeline|Fix read marker when paginating room timeline|
+First, search the issue tracker and discussions for similar issues. Tip: also
+search for [closed issues] and [discussions] — your issue might have already
+been fixed!
 
-It is not always possible to phrase every change in such a manner, but it is desired.
+> [!NOTE]
+>
+> If there is an _open_ issue or discussion that matches your problem,
+> **please do not comment on it unless you have valuable insight to add**.
+>
+> GitHub has a very _noisy_ set of default notification settings which
+> sends an email to _every participant_ in an issue/discussion every time
+> someone adds a comment. Instead, use the handy upvote button for discussions,
+> and/or emoji reactions on both discussions and issues, which are a visible
+> yet non-disruptive way to show your support.
 
-**The smaller the set of changes in the pull request is, the quicker it can be reviewed and merged.** Splitting tasks into multiple smaller pull requests is often preferable.
+If your issue hasn't been reported already, open an ["Issue Triage"] discussion
+and make sure to fill in the template **completely**. They are vital for
+maintainers to figure out important details about your setup.
 
-Also, we use [ESLint](https://eslint.org/) for clean and stylistically consistent code syntax, so make sure your pull request follow it.
+> [!WARNING]
+>
+> A _very_ common mistake is to file a bug report either as a Q&A or a Feature
+> Request. **Please don't do this.** Otherwise, maintainers would have to ask
+> for your system information again manually, and sometimes they will even ask
+> you to create a new discussion because of how few detailed information is
+> required for other discussion types compared to Issue Triage.
+>
+> Because of this, please make sure that you _only_ use the "Issue Triage"
+> category for reporting bugs — thank you!
 
-**For any query or design discussion, join our [Matrix room](https://matrix.to/#/#cinny:matrix.org).**

+### I have an idea for a feature
+
+Like bug reports, first search through both issues and discussions and try to
+find if your feature has already been requested. Otherwise, open a discussion
+in the ["Feature Requests, Ideas"] category.
+
+["feature requests, ideas"]: https://github.com/cinnyapp/cinny/discussions/new?category=feature-requests-ideas
+
+### I've implemented a feature
+
+1. If there is an issue for the feature, open a pull request straight away.
+2. If there is no issue, open a discussion and link to your branch.
+3. If you want to live dangerously, open a pull request and
+   [hope for the best](#pull-requests-implement-an-issue).
+
+### I have a question which is neither a bug report nor a feature request
+
+Open an [Q&A discussion], or join our [Matrix Space] and ask away in the
+`Cinny` room.
+
+Do not use other rooms to ask for help as our rooms are mostly specific
+topic only. If you do ask a question there, you will be redirected
+to `Cinny` room instead.
+
+> [!NOTE]
+> If your question is about a missing feature, please open a discussion under
+> the ["Feature Requests, Ideas"] category. If Cinny is behaving
+> unexpectedly, use the ["Issue Triage"] category.
+>
+> The "Q&A" category is strictly for other kinds of discussions and do not
+> require detailed information unlike the two other categories, meaning that
+> maintainers would have to spend the extra effort to ask for basic information
+> if you submit a bug report under this category.
+>
+> Therefore, please **pay attention to the category** before opening
+> discussions to save us all some time and energy. Thank you!
+
+[q&a discussion]: https://github.com/cinnyapp/cinny/discussions/new?category=q-a
+[matrix space]: https://matrix.to/#/#cinny:matrix.org
+
+## General Patterns
+
+### Issues are Actionable
+
+The Cinny [issue tracker](https://github.com/cinnyapp/cinny/issues)
+is for _actionable items_.
+
+Unlike some other projects, Cinny **does not use the issue tracker for
+discussion or feature requests**. Instead, we use GitHub
+[discussions](https://github.com/cinnyapp/cinny/discussions) for that.
+Once a discussion reaches a point where a well-understood, actionable
+item is identified, it is moved to the issue tracker. **This pattern
+makes it easier for maintainers or contributors to find issues to work on
+since _every issue_ is ready to be worked on.**
+
+If you are experiencing a bug and have clear steps to reproduce it, please
+open an issue. If you are experiencing a bug but you are not sure how to
+reproduce it or aren't sure if it's a bug, please open a discussion.
+If you have an idea for a feature, please open a discussion.
+
+### Pull Requests Implement an Issue
+
+Pull requests should be associated with a previously accepted issue.
+**If you open a pull request for something that wasn't previously discussed,**
+it may be closed or remain stale for an indefinite period of time. I'm not
+saying it will never be accepted, but the odds are stacked against you.
+
+Issues tagged with "feature" represent accepted, well-scoped feature requests.
+If you implement an issue tagged with feature as described in the issue, your
+pull request will be accepted with a high degree of certainty.
+
+> [!NOTE]
+>
+> **Pull requests are NOT a place to discuss feature design.** Please do
+> not open a WIP pull request to discuss a feature. Instead, use a discussion
+> and link to your branch.

+# Developing Cinny
+
+> [!TIP]
+> We recommend using a version manager as versions change very quickly.
+> You will likely need to switch between multiple Node.js versions based
+> on the needs of different projects you're working on. [NVM-windows]
+> on Windows and [nvm] on Linux/macOS are pretty good choices. Recommended
+> nodejs version is Krypton LTS (v24.13.1).

+[nvm-windows]: https://github.com/coreybutler/nvm-windows#installation--upgrades
+[nvm]: https://github.com/nvm-sh/nvm
+
+Execute the following commands to start a development server:
+
+```sh
+npm ci # Installs all dependencies
+npm start # Serve a development version
+```
+
+To build the app:
+
+```sh
+npm run build # Compiles the app into the dist/ directory
+```
+
+To commit changes:
+
+```sh
+npm run commit
+```
+
+## Running with Docker
+
+This repository includes a Dockerfile, which builds the application from
+source and serves it with Nginx on port 80. To use this locally, you can
+build the container like so:
+
+```
+docker build -t cinny:latest .
+```
+
+You can then run the container you've built with a command similar to this:
+
+```
+docker run -p 8080:80 cinny:latest
+```
+
+This will forward your `localhost` port 8080 to the container's port 80.
+You can visit the app in your browser by navigating to `http://localhost:8080`.
+
+## Code formatting
+
+We use [ESLint](https://eslint.org/) for clean and stylistically
+consistent code syntax, so make sure your pull request follow it.

 ## Self-hosting
-To host Cinny on your own, simply download the tarball from [GitHub releases](https://github.com/cinnyapp/cinny/releases/latest), and serve the files from `dist/` using your preferred webserver. Alternatively, you can just pull the docker image from [DockerHub](https://hub.docker.com/r/ajbura/cinny) or [GitHub Container Registry](https://github.com/cinnyapp/cinny/pkgs/container/cinny).

 * The default homeservers and explore pages are defined in [`config.json`](config.json).
 
-* You need to set up redirects to serve the assests. Example configurations; [netlify](netlify.toml), [nginx](contrib/nginx/cinny.domain.tld.conf), [caddy](contrib/caddy/caddyfile).
-    * If you have trouble configuring redirects you can [enable hash routing](config.json#L35) — the url in the browser will have a `/#/` between the domain and open channel (ie. `app.cinny.in/#/home/` instead of `app.cinny.in/home/`) but you won't have to configure your webserver.
