 # Start Contributing to Typelevel
 
-Typelevel projects power a large part of the functional Scala ecosystem. They are also complex, long-lived codebases with active communities. Contributing can feel intimidating at first, but the path in is actually quite simple! 
+Typelevel projects power a large part of the functional Scala ecosystem. They are also complex, long-lived codebases with active communities. Contributing can feel intimidating at first, but even bug reports, small fixes, and documentation updates help move our projects forward!
 
-Build something small with Cats Effect. Try streaming something with FS2. Use http4s for a simple service. Build with [Typelevel Toolkit](https://typelevel.org/toolkit/). Build a static site with Laika.
 
-> Become a user of the ecosystem you want to contribute to.
+**Become a user of the ecosystem you want to contribute to.**
 
-Also some tips that works well across most Typelevel repositories:
+- Use the [Typelevel Toolkit](https://typelevel.org/toolkit/) to experiment with [Cats](https://typelevel.org/cats) and [Cats Effect](https://typelevel.org/cats-effect/). 
+- Try streaming something with [FS2](https://fs2.io/#/). 
+- Use [http4s](https://http4s.org/) for a simple service. 
+- Build a static site with [Laika](https://typelevel.org/Laika).
 
-#### Find something that can be improved
+
+**Find something that can be improved**
 - Look for open issues, especially those labeled `good first issue` or `help wanted`.
 - Browse the curated [good-first-issues board](https://github.com/orgs/typelevel/projects/1/).
 - If you're already using the library, improve something that bothered you.
 - Documentation and tests are excellent starting points too.
 
-#### Understand the problem first
+**Understand the problem**
 - Read the issue carefully, understand the current implementation.
 - Look for existing PRs or recent comments.
 - Check whether a solution was already proposed.
 
-#### Communication is Key
+**Communication with the community**
 - Comment on the issue saying you'd like to work on it and briefly describe your idea or approach.
 - Ask clarifying questions if anything is unclear.
 - If the change is small, you can open a draft PR early to get feedback.
 
-#### Open a PR and iterate
+**Open a PR and iterate**
 - Fork the repo, create a branch, and implement the change. Add or update tests where appropriate.
 - Open a PR with a clear description of the problem and your solution.
 - Expect review feedback, ask questions, adjust your changes, and iterate.
 
-#### Where to Ask for Help
+## Where to Ask for Help
 - Join the [Typelevel Discord](https://discord.gg/typelevel-632277896739946517).
 - Ask in `#starting-contributing` if you're new to contributing.
 - Use library-specific channels like `#cats`, `#cats-effect`, `#fs2`, or `#http4s` for more focused questions.
 - You can also ask directly on a GitHub issue if your question is specific to that issue.
