Add "How-to-build" and "How-to-install" info on README

[filfreire]

I suggest adding to the README file "how to build" the project locally and how to maybe install it (similarly to info on website), for any newcomers to find that info right on the README.

That's a really good idea (improving the docs has been in the ToDo list since forever)

I was just searching for something similar.

As someone new to this, I'm getting stuck at a few points.

I've got the application installed (After installing apcu).

I assumed it had a backend but I see now that it's cli/rest only, but I have no idea how to create an api key.

I installed the react app in a subfolder which didn't work until I edited the file and corrected the paths to where I installed it.
Then trying to add a server, I realised I have no idea how to create an api key and can't find any docs on the available commands or how to list them.

Thanks for your insterest @robwent.

The docs need improvement, yes. I will work on it as soon as I have the time.

API keys can only be created from the CLI. Just run bin/cli api-key:generate. The command will output the generated API key.

You can see any available commands by simply running bin/cli with no arguments.

Yep, I feel a bit dumb now.

I just ran /bin/cli and got a list of all the commands!
