+  ALE: allows you to lint while you type.
+---
+
+To update (replacing the current version) run `webi vim-ale`.
+
+## Cheat Sheet
+
+> ALE (Asynchronous Lint Engine) is a plugin providing linting (syntax checking
+> and semantic errors) in NeoVim 0.2.0+ and Vim 8 while you edit your text
+> files, and acts as a Vim Language Server Protocol client.
+
+ALE is the spiritual successor to Syntastic.
+
+This installer includes a few reasonable defaults.
+
+### How to install and configure manually
