+# Elixir and Phoenix Pack
+
+Adds baseline support for Elixir/Phoenix projects.
+
+This plugin pack does the following:
+
+- Adds the `tailwindcss` AstroCommunity pack
+- Adds the `elixirls` language server
+- Adds the `elixir` and `heex` Treesitter parsers
+- Ensures `tailwindcss` is configured for html-eex and `class:` style hinting.
