You need docker for this to work on your local. If you have docker, you can technically skip out on installing any other dependencies.
You also need ngrok to get events into your system.
Go to slack and create a new app. Lets call this new app Marbles
copy over the app manifest from manifest.json file present here into the app manifest (JSON format)
copy the CLIENT ID and CLIENT SECRET into the docker compose file environment
then just run
docker-compose up
The application port will be at http://localhost:3003
You have to run ngrok http 3003
and copy over the port forwarded ngrok url to the manifest inside slack app.
Note: Do not forget the /events part when you do this
go to http://localhost:3003/auth
This will open up install into workplace folder
after install to workplace, you will set it hitting https://localhost:3003/callback and breaking, since its not exposed to https
Just modify the url by replacing https with http and your slack application will get connected
