 Set `symbol_index_provider: lsp` to use a language server; it falls back to regex indexing if the LSP binary is missing. Configure `symbol_index_lsp_languages` and `symbol_index_lsp_command` to match your server (for example, `typescript-language-server --stdio` with `ts`/`tsx` language IDs).
 
+### LSP Symbol Index Examples (All Common Languages)
+
+Pick one LSP server per run (one `symbol_index_lsp_command`). Update the language map to match the server you installed.
