+--- `css-languageserver` can be installed via `npm`:
+---
+--- ```sh
+--- npm i -g vscode-langservers-extracted
+--- ```
+---
+--- Neovim does not currently include built-in snippets. `vscode-css-language-server` only provides completions when snippet support is enabled. To enable completion, install a snippet plugin and add the following override to your language client capabilities during setup.
+---
+--- ```lua
+--- --Enable (broadcasting) snippet capability for completion
+--- local capabilities = vim.lsp.protocol.make_client_capabilities()
+--- capabilities.textDocument.completion.completionItem.snippetSupport = true
+---
+--- vim.lsp.config('cssls', {
+---   capabilities = capabilities,
+--- })
