# Contributing
`crowbook` is a free software, and you can contribute to it.
There are some things that can be accessible even if you don't know anything about programming.
## Internationalization
`crowbook` aims to support multiple languages.
However, unfortunately, currently only English, French, and (in a more limited way) Spanish are currently supported.
If you want to have better support for the language you write in, there are easy things you can do:
* Provide a translation for the few strings that Crowbook insert into the rendered documents.
This is really easy, as there are currently less than a dozen of them, and you just need to create a new variant of the
[`./lang/en.yaml`](https://github.com/lise-henry/crowbook/blob/master/lang/en.yaml)
file.
* Open an
[issue](https://github.com/lise-henry/crowbook/issues)
about the typographic rules in your language, if `crowbook` doesn't cover them.
* Provide a translation for the `crowbook` program.
It requires creating a variant of the
[`.po` file](https://github.com/lise-henry/crowbook/blob/master/lang/fr.po),
which is a bit more work because (at this time) it's around 1,500 lines (and less a priority than the first item of this list, as this translation only affects the the command-line interface and not the rendered documents).
