To make working on documentation a bit more comfortable, we extracted the sources of everything seen at https://xod.io/docs/ to a separate GitHub repository. From now on, all changes to docs should go there.
The change relaxes the strict process enforced in the main repo and does not require the long and heavy process of continuous integration which re-builds and re-tests everything on any letter change.
If you would like to help in improving the docs, see the CONTRIBUTING. I hope it makes the process more clear.
