Documentation

The Sapphire documentation is deployed as part of the official Oasis documentation. To make changes visible on the docs website:

1. Merge any changes in the docs folder to the main branch.
2. Bump the git commit reference of the Sapphire submodule inside the external directory of the Oasis docs repository (you can simply approve the auto-generated dependabot's submodule bump PR).
3. Merge changes into Oasis docs repository main branch. CI will deploy the docs to the website automatically.

Note: If you want to introduce a new markdown file, you will need to add it to the Oasis documentation's sidebar. If you remove any chapters, don't forget to define sensible redirects. For more info on how to write the Oasis documentation, manage images and diagrams, reference cross-repo markdown files and similar consult the official README.

The API documentation is auto-generated from the corresponding Sapphire clients and libraries. It is deployed at:

• https://api.docs.oasis.io/js/sapphire-paratime/
• https://api.docs.oasis.io/sol/sapphire-contracts/

The API docs are generated automatically every 15 minutes from the main branch.
