After that, you can check out some starter project templates on GitHub to build your own base template (= your theme) for your client projects.
Some examples:
- https://github.com/madebyshape/craft-cms
- https://github.com/CreateSean/craft-starter
- https://github.com/vigetlabs/craft-site-starter
- https://github.com/szenario-fordesigners/craft-vite-starter
- https://github.com/craftcms/europa-museum
- https://github.com/davidhellmann/craftcms-baukasten
To be fair: craft cms has no official directory for these yet like the WP themes directory - would be helpful for newbies. Demo: https://craftcms-launchpad.mandrasch.eu/
Have fun!
