# Documentation Contributions

Adding new content to our documentation is very straight forward.

## Contributing

The documentation works in two different ways:

* `Handbook` (hosted on GitBook at [docs.devland.is](https://docs.devland.is)) which contains all the documentation regarding all the island.is projects. You will find technical overview, architectural decisions, API design guide, devops guide, code reviews guide, X-Road guide, code standards detailed information and much more. If you need to edit an existing documentation or create a new page inside the handbook, you simply go to [app.gitbook.com](https://app.gitbook.com) and start writing your content and make a change request.
* `Technical developer guides` which are all the READMEs from the `apps` and `libs` directories in our [GitHub repository](https://github.com/island-is/island.is). If you need to edit or create new content follow our [External Contributions guide](/development/external-contribute.md) and make the corresponding changes in the GitHub repository. We recommend using [this template](/misc/gitbook-template.md) when you create a new app in the `apps` directory.
