I’ve just setup BookStack on my server and I have no idea how I’ve not come across it sooner! It looks like a wonderful tool. I’m hoping to use it to document my home LAN and apps, but I can see it being used for so much more. Thanks for the integration ideas in this video, I’ve learned now I can use my HA setup to receive webhooks. Very cool!
Not built-in but it is possible to customize the webhook format using our logical theme system (github.com/BookStackApp/BookStack/blob/development/dev/docs/logical-theme-system.md). I would require a fair amount of added logic though to calculate those figures you desire.
