It's not the best place to get updates.

 ## FAQ
 
-### Why not `mocha`, `tape`, `tap`?
-
-Mocha requires you to use implicit globals like `describe` and `it` with the default interface (which most people use). It's not very opinionated and executes tests serially without process isolation, making it slow.
-
-Tape and tap are pretty good. AVA is highly inspired by their syntax. They too execute tests serially. Their default [TAP](https://testanything.org) output isn't very user-friendly though so you always end up using an external tap reporter.
-
-In contrast AVA is highly opinionated and runs tests concurrently, with a separate process for each test file. Its default reporter is easy on the eyes and yet AVA still supports TAP output through a CLI flag.
-
 ### How is the name written and pronounced?
 
 AVA, not Ava or ava. Pronounced [`/ˈeɪvə/`](media/pronunciation.m4a?raw=true): Ay (f**a**ce, m**a**de) V (**v**ie, ha**v**e) A (comm**a**, **a**go)
