DSM repository sources
The GitHub workflow in this repo uploads a JSON with package metadata to s3://repo.homebridge.io which appears to be an S3 bucket used by the DSM repo https://synology.homebridge.io. Is the source code of the DSM repo available somewhere? I'd like to distribute an SPK myself so that I can auto-update existing installations, but didn't find an easy way to implement a DSM repo.

I tried to figure out how synology.homebridge.io works but I always get an empty package list as a result (`{"packages":[]}`).
