Hello! I created a Slack App called Wolivo
It allows you to save and retrieve useful information for your team and yourself with a single command. That way you can document a particular process directly in slack and everyone from your team can access it.
For example, create a command to document how to create an event

Event

Then see all the commands you have created in your dashboard

Dashboard

Technologies I used: Nodejs, Expressjs, Slack API, Stripe
You can add the app on Slack for free if you want to test it ( https://wolivo.com )

Let me know if you have a question!
