## Installation

You need a Python 3 interpreter, [`uv`](https://docs.astral.sh/uv/) and the `inotify-tools` installed. All this has been tested under Fedora Linux 42 on my laptop and Ubuntu latest in the CI workflows. Let me know if it works on your system.

Get the source code:

```ShellSession
$ git clone https://github.com/flepied/second-brain-agent.git
```

Copy the example .env file and edit it to suit your settings:

```ShellSession
$ cp example.env .env
```

Install the dependencies using [uv](https://docs.astral.sh/uv/):

```ShellSession
$ uv sync --all-extras
```

`chromadb` is intentionally not installed through `uv`. This repository loads the
Python package directly from a sibling checkout at `../chroma/chromadb` so local
development can reuse the Chroma Python sources without building the native
Chroma package. The actual Chroma server still runs in Docker.

The Chroma container persists its database under `/chroma/chroma`, so
[`compose.yaml`](compose.yaml) bind-mounts `$DSTDIR/Db` there. If that mount
target changes, `sba-txt` will rebuild the vector database on the next start.

Then to activate the virtual environment, do:

```ShellSession
$ source .venv/bin/activate
```
