+The `lsp` component covers Rust, Python, Go, Bash, Markdown, TOML,
+Terraform/HCL, Dockerfile, Docker Compose, R, YAML, JSON, and Lua. The `ai`
+supergroup includes this local code-intelligence layer. Selecting `lsp` alone
+does **not** authorize or configure Hermes, Codex, Cursor, OpenCode, Ollama, or
+any cloud provider. DOTS owns PATH-visible binaries; Neovim configures clients
+without downloading duplicate Mason copies. See the
+[language-server guide](docs/using/language-servers.md).
 
 Full subsystem detail lives under `docs/` — not in this README.
