Here are Commandant's docs built on Linux with Jazzy and SourceKitten: https://static.realm.io/jazzy_demo/Commandant

The rough steps are:

1. Have libsourcekitdInProc.so and Swift 3 available.
2. Install the jazzy ruby gem.
3. Build SourceKitten.
4. Build Swift Package Manager module.
5. Generate JSON docs for SwiftPM module using SourceKitten.
