The tutorial that the "DjangoGirls" initiative is using for all of its workshops. It's a very beginner-friendly tutorial with introductions to the command line, Python, Django, HTML and CSS. No previous programming experience is required.

Once participants have finished the tutorial, they will have a small working web application: their own blog. The tutorial will show them how to put it online, so others will see their work.

The tutorial is available in English, French, Chinese and Ukrainian. "beta" versions of translations to other languages are also available. (The English version is considered the "original" and is usually the most maintained, complete and up-to-date one.)
