Hi! This is what will make Expo actually be useable by people. :)

Expo's SDK is versioned so that apps made on old SDKs are still supported when new SDKs are relased. The website documents previous SDK versions too.

Version names correspond to directory names under versions/.

unversioned is a special version for the next SDK release. devdocs isn't actually an SDK version, it's a special version that corresponds to the "Tool Developer Documentation" website.

Sometimes you want to make an edit in version X and have that edit also be applied in versions Y, Z, ... (say, when you're fixing documentation for an API call that existed in old versions too). You can use the ./scripts/versionpatch.sh utility to apply your git diff in one version in other versions. For example, to update the docs in unversioned then apply it on v8.0.0 and v7.0.0, you'd do the following after editing the docs in unversioned such that it shows up in git diff:

./scripts/versionpatch.sh unversioned v8.0.0 v7.0.0

Any changes in your git diff outside the unversioned directory are ignored so don't worry if you have code changes or such elsewhere.

Thanks for helping! :D make your changes on a fork of this repository or whatever works for you and submit a pull request. We'll take a look and incorporate them!

• Make your changes in universe/docs and commit them. Our shipit bot synchronizes the changes to the public expo-docs repository. Changes will automatically be deployed to https://docs.expo.io on deploy. To change the default version, update the version key in docs/package.json (the deploy script will respect this value).

Make sure your machine has Docker for Mac. If it doesn't go to https://docs.docker.com/docker-for-mac/ and download and install it.

Be sure you've run all unigulp-y things.
