+### Other Editors
+
+Any editor that implements the Language Server Protocol should be compatible with Codebook. To get started, follow the [installation instructions](#installation), then consult your editor's documentation to learn how to configure and enable a new language server.

+
+```sh
+codebook-lsp serve
+```
