 ## Contributing to scanline
 
-scanline was a quick and dirty first project. While portions of the code have been rewritten more recently, a lot of it displays some pretty unevolved style. I welcome your pull requests, but please know what you're getting yourself into!
+If you're interested in making a change, fix, or enhancement to scanline, please do! I'd appreciate a heads up on any bigger changes, and I'm happy to review any PRs.
 
 You can also contact me with any questions or suggestions and I'll do my best to work them in eventually.
