 An analyzer is a tool that analyzes the AST of an exercise solution looking for specific features. Based on the results, it can leave helpful comments for the student.
 
-Some v3 concept exercises must have an analyzer. They won't be mentored, and their goal is to teach how to use specific features of the language, so we need to look out for solutions that pass the tests, but don't use the taught features.

 ### 3. Check open issues and PRs in other repos
 
-To launch v3, we need a well-working analyzer, test runner, and representer. All of those projects are already created and functional, but they might still need some improvements.
-
-V3 is our current focus, but really don't want to get involved with it at the moment, you can also check if the current Elixir track has open issues or PRs that could benefit from more attention.
+Browse all the open issues in all the Elixir track repositories and choose something that sounds interesting! If an issue is tagged with "help wanted", that means it's well suited for all contributors interested in helping out. Issues without this label are meant for the regular track maintainers.
