Django

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Thanks for checking it out.

All documentation is in the "docs" directory and online at https://docs.djangoproject.com/en/stable/. If you're just getting started here's how we recommend you read the docs:

• First, read docs/intro/install.txt for instructions on installing Django.
• Next, work through the tutorials in order (docs/intro/tutorial01.txt docs/intro/tutorial02.txt, etc.).
• If you want to set up an actual deployment server, read docs/howto/deployment/index.txt for instructions.
• You'll probably want to read through the topical guides (in docs/topics) next; from there you can jump to the HOWTOs (in docs/howto) for specific problems, and check out the reference (docs/ref) for gory details.
• See docs/README for instructions on building an HTML version of the docs.

Docs are updated rigorously. If you find any problems in the docs, or think they should be…
