+---@brief
+---
+--- https://github.com/remoteoss/dexter
+---
+--- `dexter` is a fast, full-featured Elixir LSP optimized for large codebases.
+---
+--- `dexter` can be installed via Homebrew, mise, or asdf:
+---
+--- Via Homebrew:
+--- ```sh
+--- brew install remoteoss/tap/dexter
+--- ```
+---
+--- Via mise:
+--- ```sh
+--- mise plugin add dexter https://github.com/remoteoss/dexter.git
+--- mise install dexter
+--- ```
+---
+--- Via asdf:
+--- ```sh
+--- asdf plugin add dexter https://github.com/remoteoss/dexter.git
+--- asdf install dexter latest
+--- ```
+---
+--- `dexter` works without compilation by parsing source files directly, providing:
+--- - Fast indexing (cold index in ~11s on 57k-file codebases)
+--- - Go-to-definition with alias and delegate resolution
+--- - Find references across the codebase
+--- - Hover documentation and autocompletion
+--- - Rename functionality with automatic file renaming
+--- - Format on save via persistent Elixir process
+---
+--- Configuration example:
+--- ```lua
+--- vim.lsp.config('dexter', {
+---   init_options = {
+---     followDelegates = true,  -- jump through defdelegate to the target function
+---     -- stdlibPath = "",      -- override Elixir stdlib path (auto-detected)
+---     -- debug = false,        -- verbose logging to stderr (view with :LspLog)
+---   },
+--- })
+--- vim.lsp.enable('dexter')
+--- ```
+---
+
+---@type vim.lsp.Config
+return {
+  cmd = { 'dexter', 'lsp' },
+  filetypes = { 'elixir', 'eelixir', 'heex' },
+  root_markers = { '.dexter/dexter.db', '.dexter.db', '.git', 'mix.exs' },
+  init_options = {
+    followDelegates = true,
+  },
+}
