Readme: add more thorough instructions

[rubo77]

This is a first try, but there seems something missing still, see #4

I appreciate your suggestions for the improved readme file to help people who aren't familiar with Laravel.

The formatting got messed up from how I had it, so I guess I'll try to make similar changes instead of merging the pull request.

What formatting is mixed up?

I added a max lilnewidth of 80 chars and added an empty line between the numbered list.

The github change-view is quite confusing though. If you watch che changes in a better GUI, you see, not so much changed. This is seen in SmartGit:

I don't like using a max line width since I prefer text-wrapping to be configurable by the reader. Most of your other modifications look good. Thanks.

[rubo77]

Ok, I removed the line wrapping changes

[rubo77]

is this still needed?

it seems like you enhanced the readme in some way already

Every ~60 days, I've been using this repo (running locally on my machine) to backup my StackExchange activity.

It had worked for years.

Suddenly it started getting these errors, which I've not yet figured out: https://stackapps.com/questions/10497/suddenly-getting-couldnt-parse-client-id

I basically haven't looked at this repo at all since ~2019 since it always just worked.

@rubo77 If you'd like to fork it, I can update my readme to point to your forked repo, for people who are interested, since I don't want to spend much (or maybe any) time improving it from here.
