+# EBNF for Zed
+
+A [Zed](https://zed.dev/) extension that provides comprehensive language support for Extended Backus-Naur Form (EBNF).
+
+## Features
+
+- **Syntax Highlighting:** Vibrant and accurate highlighting for EBNF rules, strings, integers, and special sequences.
+- **Bracket Matching:** Support for rainbow brackets and active bracket highlighting for standard brackets `()`, `{}`, `[]`, as well as EBNF-specific sequences like `(/ /)` and `(: :)`.
+- **Auto-Closing & Indentation:** Smart bracket auto-closing and indentation behaviors when writing rules.
+- **Outline Panel Support:** Quickly navigate large grammar files using Zed's Outline panel (`cmd-shift-O` or `ctrl-shift-O`).
