# Important Notes - Binary LS endpoint is not yet handled. - The parsing of provided source is not entirely correct, as each line (including imports) is treated as node. The usage of actual enso AST for nodes is not yet implemented. - Modifications to the graph state are not yet synchronized back to the language server.
