The documentation for Compose has been merged into the general documentation repo.
The docs for Compose are now here: https://github.com/docker/docker.github.io/tree/master/compose
Please submit pull requests for unpublished features on the vnext-compose branch (https://github.com/docker/docker.github.io/tree/vnext-compose).
If you submit a PR to this codebase that has a docs impact, create a second docs PR on docker.github.io. Use the docs PR template provided (coming soon - watch this space).
PRs for typos, additional information, etc. for already-published features should be labeled as okay-to-publish (we are still settling on a naming convention, will provide a label soon). You can submit these PRs either to vnext-compose or directly to master on docker.github.io
As always, the docs remain open-source and we appreciate your feedback and pull requests!
