[heimwege]

The readme.md of the create command will now be auto-generated with each build. It uses the description from the commands and subcommands. No need to manually update the readme.md ever again 🥳

Hey @lfindlaysap I basically just moved stuff from the "old" readme to the description of each command so that the auto-generation of the "new" readme will have more or less the same description as before. There should not really be any changes in the wording, but to be on the save sid would be great if you could check.
Easiest for you would be to check and comment the readme.md file that is now generated based on the command descriptions. I can then adjust the texts in the respective sources if needed and re-generate the readme.md. Then you don't need to dig into the source code files 🐱
