 Continue indexes your codebase so that it can later automatically pull in the most relevant context from throughout your workspace. This is done via a combination of embeddings-based retrieval and keyword search. By default, all embeddings are calculated locally with `all-MiniLM-L6-v2` and stored locally in `~/.continue/index`.

-Currently, the codebase retrieval feature is available as the "codebase" context provider. You can use it by typing `@codebase` in the input box, and then asking a question. The contents of the input box will be compared with the embeddings from the rest of the codebase to determine relevant files.
+Currently, the codebase retrieval feature is available as the "codebase" and "folder" context providers. You can use them by typing `@codebase` or `@folder` in the input box, and then asking a question. The contents of the input box will be compared with the embeddings from the rest of the codebase (or folder) to determine relevant files.
