# smolbren: local search for your Markdown vaults

> smolbren indexes your Markdown notes into a queryable knowledge graph with BM25 full-text search. Fully local, agent-ready JSON output.

Welcome to **smolbren** — an ontology-first search CLI for Markdown vaults. It turns your frontmatter into a typed knowledge graph, layers BM25 full-text search on top, and exposes everything through single-line JSON output that agents and scripts can consume directly. No server, no cloud, no configuration sprawl — just your notes and a fast local index.

## Get started in three steps

<Steps>
  <Step title="Install smolbren">
    Make sure you have the [Rust toolchain](https://rustup.rs/) and `protoc` on your `PATH`, then install from crates.io:

    ```sh theme={null}
    cargo install smolbren
    ```
  </Step>

  <Step title="Register your vault">
    Point smolbren at your Markdown directory. The first vault you add automatically becomes the default:

    ```sh theme={null}
    smolbren vault add personal ~/notes --default
    ```
  </Step>

  <Step title="Index and search">
    Build the index (incremental by default — only changed files are re-read), then start querying:

    ```sh theme={null}
    smolbren index
    smolbren search "context engineering"
    smolbren query "MATCH (n:blog) RETURN n.title LIMIT 5"
    ```
  </Step>
</Steps>
