# Boot snippet {#root}

@status:doc/work @audience:user,agent

[p01] `org.vibevm.world/source-mirrors@1.0.0` contributes a boot snippet: text that a session reads before it starts work, placed into the project's generated boot lane by `vibe install`. It is not read on this page — it is read by the agent.

[p02]
```toml
[boot_snippet]
category = "flow"
source = "vibevm/vibespecs/boot/62-flow-source-mirrors.xml"

```
