I create the issue mainly for myself but if there's anyone who wants to lend a hand then I would love it of course :)

• Error Handling
• Concurrency & Parallelism
• Testing
• Resource Safety
• Cancelation
• Interop (Monix, Cats-Effect, Future)
• Creating BIO
• Running BIO
• Thread Management
• Project's motivation and comparison to other solutions (Cats IO, Future, Monix Task, ZIO)
• More exciting landing section
• Update Scaladocs

In the future I would like to add sample project as well
