 ## Contributing
 
-We are always looking for contributions from **all skill levels**!

If you're looking to ease your way into the project try out a [good first issue](https://github.com/GitHawkApp/GitHawk/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22).

 #### Highest Priority Needs:
 
 - 👩‍💼 **Product Manager**
-  - We have some [projects](https://github.com/GitHawkApp/GitHawk/projects) and tons of unorganized/unprioritized [features](https://github.com/GitHawkApp/GitHawk/issues?q=is%3Aissue+is%3Aopen+label%3Afeature-request). GitHawk needs someone to own the product direction!

 - 👩‍🎨 **Designer**
   - Like making unique UIs? So do we! We value keeping GitHawk's UX close to core iOS, but, when necessary, create our own high-quality UI components. Helping design for GitHawk is a great opportunity to try new ideas out!
