 * Never create files with `mod.rs` paths - prefer `src/some_module.rs` instead of `src/some_module/mod.rs`.
+* When creating new crates, prefer specifying the library root path in `Cargo.toml` using `[lib] path = "...rs"` instead of the default `lib.rs`, to maintain consistent and descriptive naming (e.g., `gpui.rs` or `main.rs`).

-Thanks for your interest in contributing to Zed, the collaborative platform that is also a code editor!
+Thank you for helping us make Zed better!
 
-All activity in Zed forums is subject to our [Code of Conduct](https://zed.dev/code-of-conduct). Additionally, contributors must sign our [Contributor License Agreement](https://zed.dev/cla) before their contributions can be merged.

 ## Contribution ideas
 
-If you're looking for ideas about what to work on, check out:
+Zed is a large project with a number of priorities. We spend most of
+our time working on what we believe the product needs, but we also love working
+with the community to improve the product in ways we haven't thought of (or had time to get to yet!)
+
+In particular we love PRs that are:
+
+- Fixes to existing bugs and issues.
+- Small enhancements to existing features, particularly to make them work for more people.
+- Small extra features, like keybindings or actions you miss from other editors or extensions.
+- Work towards shipping larger features on our roadmap.
+
+If you're looking for concrete ideas:
 
-- Our [public roadmap](https://zed.dev/roadmap) contains a rough outline of our near-term priorities for Zed.
 - Our [top-ranking issues](https://github.com/zed-industries/zed/issues/5393) based on votes by the community.
+- Our [public roadmap](https://zed.dev/roadmap) contains a rough outline of our near-term priorities for Zed.
 
-For adding themes or support for a new language to Zed, check out our [docs on developing extensions](https://zed.dev/docs/extensions/developing-extensions).
+## Sending changes
 
-## Proposing changes
+The Zed culture values working code and synchronous conversations over long
+discussion threads.
 
-The best way to propose a change is to [start a discussion on our GitHub repository](https://github.com/zed-industries/zed/discussions).
+The best way to get us to take a look at a proposed change is to send a pull
+request. We will get back to you (though this sometimes takes longer than we'd
+like, sorry).
 
-First, write a short **problem statement**, which _clearly_ and _briefly_ describes the problem you want to solve independently from any specific solution. It doesn't need to be long or formal, but it's difficult to consider a solution in absence of a clear understanding of the problem.
+Although we will take a look, we tend to only merge about half the PRs that are
+submitted. If you'd like your PR to have the best chance of being merged:
 
-Next, write a short **solution proposal**. How can the problem (or set of problems) you have stated above be addressed? What are the pros and cons of your approach? Again, keep it brief and informal. This isn't a specification, but rather a starting point for a conversation.
+- Include a clear description of what you're solving, and why it's important to you.
+- Include tests.
+- If it changes the UI, attach screenshots or screen recordings.
 
-By effectively engaging with the Zed team and community early in your process, we're better positioned to give you feedback and understand your pull request once you open it. If the first thing we see from you is a big changeset, we're much less likely to respond to it in a timely manner.
+The internal advice for reviewers is as follows:
 
-## Pair programming
+- If the fix/feature is obviously great, and the code is great. Hit merge.
+- If the fix/feature is obviously great, and the code is nearly great. Send PR comments, or offer to pair to get things perfect.
+- If the fix/feature is not obviously great, or the code needs rewriting from scratch. Close the PR with a thank you and some explanation.
 
-We plan to set aside time each week to pair program with contributors on promising pull requests in Zed. This will be an experiment. We tend to prefer pairing over async code review on our team, and we'd like to see how well it works in an open source setting. If we're finding it difficult to get on the same page with async review, we may ask you to pair with us if you're open to it. The closer a contribution is to the goals outlined in our roadmap, the more likely we'll be to spend time pairing on it.
+If you need more feedback from us: the best way is to be responsive to
+Github comments, or to offer up time to pair with us.
 
-## Mandatory PR contents
+If you are making a larger change, or need advice on how to finish the change
+you're making, please open the PR early. We would love to help you get
+things right, and it's often easier to see how to solve a problem before the
+diff gets too big.
 
-Please ensure the PR contains
+## Things we will (probably) not merge
 
-- Before & after screenshots, if there are visual adjustments introduced.
+Although there are few hard and fast rules, typically we don't merge:
 
-Examples of visual adjustments: tree-sitter query updates, UI changes, etc.
-
-- A disclosure of the AI assistance usage, if any was used.
-
-Any kind of AI assistance must be disclosed in the PR, along with the extent to which AI assistance was used (e.g. docs only vs. code generation).
-
-If the PR responses are being generated by an AI, disclose that as well.
-
-As a small exception, trivial tab-completion doesn't need to be disclosed, as long as it's limited to single keywords or short phrases.
-
-## Tips to improve the chances of your PR getting reviewed and merged
-
-- Discuss your plans ahead of time with the team
-- Small, focused, incremental pull requests are much easier to review
-- Spend time explaining your changes in the pull request body
-- Add test coverage and documentation
-- Choose tasks that align with our roadmap
-- Pair with us and watch us code to learn the codebase
-- Low effort PRs, such as those that just re-arrange syntax, won't be merged without a compelling justification

-## File icons
-
-Zed's default icon theme consists of icons that are hand-designed to fit together in a cohesive manner.
-
-We do not accept PRs for file icons that are just an off-the-shelf SVG taken from somewhere else.
-
-### Adding new icons to the Zed icon theme
-
-If you would like to add a new icon to the Zed icon theme, [open a Discussion](https://github.com/zed-industries/zed/discussions/new?category=ux-and-design) and we can work with you on getting an icon designed and added to Zed.
+- Anything that can be provided by an extension. For example a new language, or theme. For adding themes or support for a new language to Zed, check out our [docs on developing extensions](https://zed.dev/docs/extensions/developing-extensions).
+- New file icons. Zed's default icon theme consists of icons that are hand-designed to fit together in a cohesive manner, please don't submit PRs with off-the-shelf SVGs.
+- Giant refactorings.
+- Non-trivial changes with no tests.
+- Stylistic code changes that do not alter any app logic. Reducing allocations, removing `.unwrap()`s, fixing typos is great; making code "more readable" — maybe not so much.
+- Features where (in our subjective opinion) the extra complexity isn't worth it for the number of people who will benefit.
+- Anything that seems completely AI generated.
 
 ## Bird's-eye view of Zed
 
+We suggest you keep the [Zed glossary](docs/src/development/glossary.md) at your side when starting out. It lists and explains some of the structures and terms you will see throughout the codebase.
+
 Zed is made up of several smaller crates - let's go over those you're most likely to interact with:
 
 - [`gpui`](/crates/gpui) is a GPU-accelerated UI framework which provides all of the building blocks for Zed. **We recommend familiarizing yourself with the root level GPUI documentation.**
