Bio

I write books and create video courses about WordPress, HTML and CSS.
Not a programmer.
Not a designer.
Not an expert.
But apparently I explain things quite well 😉

WordPress Origin Story

Way back I had b2/cafelog installed.
When it was discontinued I did not go for WordPress.
In the years following I tried it every now and again.
Finally did go for WP in 2015 and never looked back.
Wrote a book about it (in German): »Einstieg in WordPress« (https://einstieg-in-wp.de/)
