Overall organisation

[lazarusA]

Hello everyone,

Welcome! I would like to start this with a few topics, please add more as necessary.

• Manage tags or categories in such a way that the landing page shows the overall structure of the organisation. Initially I would suggest to add a README.md file to the org. Similar to this one here.
• Pinned repositories
• Set a new title and subtitle for the organisation.
• New logo for the org
• Update webpage link with a working page (after converging into a given structure).
• Discuss what should be started in this org and what could be transferred or simply add links in the overview.
