+  Neovim Vim-Fork Text Editor
+description: |
+  Neovim is a Vim fork focused on extensibility and usability
+---
+
+To update or switch versions, run `webi nvim@stable` (or `@v0.6.1`, etc).
+
+## Cheat Sheet
+
+> A Neovim is a project that seeks to aggressively refactor Vim in order to:
+> - Simplify maintenance and encourage contributions
+> - Split the work between multiple developers
+> - Enable advanced UIs without modifications to the core
+> - Maximize extensibility
+
+```bash
+nvim <FILE_PATH> # starts up neovim editor with file
+```
