## FAQ

### How do I install BrainLayer?

You can install it via pip using the command `pip install brainlayer`.

### Does BrainLayer require cloud services or Docker?

No, it is a local-first solution that uses a single SQLite file with no cloud or Docker requirements.

The `brain_store` tool will return an explicit outcome of `DUPLICATE`, which is considered a success; you should not attempt to re-store it.

### Can BrainLayer help multiple agents share information?
