+--- @brief
+--- The `vim.lsp.completion` module enables insert-mode completion driven by an LSP server. Call
+--- `enable()` to make it available through Nvim builtin completion (via the |CompleteDone| event).
+--- Specify `autotrigger=true` to activate "auto-completion" when you type any of the server-defined
+--- `triggerCharacters`.
+---
+--- Example: activate LSP-driven auto-completion:
+--- ```lua
+--- vim.lsp.start({
+---   name = 'ts_ls',
+---   cmd = …,
+---   on_attach = function(client, bufnr)
+---     vim.lsp.completion.enable(true, client.id, bufnr, {
+---       autotrigger = true,
+---       convert = function(item)
+---         return { abbr = item.label:gsub('%b()', '') }
+---       end,
+---     })
+---   end,
+--- })
+--- ```
