Rewrite the README.md file

[miha42-github]

The README.md file doesn't reflect the current state of the service and needs to be improved. The major focus will be on the installation and startup process. Additionally, the overall motivation section, status, etc. needs to be updated to reflect the change in strategy. We will reuse as much as possible and add appropriate screenshots to enrich the documentation. We can and should also consider bringing links to the documentation so users can see an example in action.

Base file rewritten, some minor changes remain to pursue:

• Update dependencies
• Add code contribution section
• Add issues section

After these are completed then we will declare this issue closed.
