feat: use two deploy branches for CI builds

This way we have two branches on GitHub that reflect the state of the
website after CI build has finished and pushed. See README.

Also adds `/build.json` to the site for easy access to build info.

 ## CI/CD
 
-- The `master` branch is automatically deployed to the production server (e.g., logos.co) through [CI](https://ci.infra.status.im)
-- The `develop` branch is automatically deployed to the staging server (e.g., dev.logos.co) through [CI](https://ci.infra.status.im)
+- [CI builds](https://ci.infra.status.im/job/website/job/guide.waku.org/) `master` and pushes to `deploy-master` branch, which is hosted at <https://guide.waku.org/>.
+- [CI builds](https://ci.infra.status.im/job/website/job/dev-guide.waku.org/) `develop` and pushes to `deploy-develop` branch, which is hosted at <https://dev-guide.waku.org/>.
 
+The hosting is done using [Caddy server with Git plugin for handling GitHub webhooks](https://github.com/status-im/infra-misc/blob/master/ansible/roles/caddy-git).
+
+Information about deployed build can be also found in `/build.json` available on the website.
