## Sync your documentation

Go into any Ruby project with a `Gemfile.lock` and run:

```bash
posh sync
```

This downloads the available documentation for your project's Ruby and gem versions
to your machine. Run it again after changing dependencies, or enable
[automatic sync with Bundler](/docs/automatic-sync/).

## Open the browser

From inside your project, run:

```bash
posh
```

POSH opens a terminal interface for browsing your project's documentation.
The documentation browser is free, with no limits.

## Clear downloaded documentation

To remove all docsets from your machine, run:

```bash
posh clear
```
