FAQ: Installation
=================

How do I get started?
---------------------

    #. `Download the code`_.
    #. Install Django (read the :doc:`installation guide </intro/install>`).
    #. Walk through the :doc:`tutorial </intro/tutorial01>`.
    #. Check out the rest of the :doc:`documentation </index>`, and `ask questions`_ if you
       run into trouble.

What are Django's prerequisites?
--------------------------------

Django requires Python_, specifically any version of Python from 2.4
through 2.7. No other Python libraries are required for basic Django
usage.

For a development environment -- if you just want to experiment with Django --
you don't need to have a separate Web server installed; Django comes with its
own lightweight development server. For a production environment, Django
follows the WSGI_ spec, which means it can run on a variety of server
platforms.  See :doc:`Deploying Django </howto/deployment/index>` for some
popular alternatives.  Also, the `server arrangements wiki page`_ contains
details for several deployment strategies.

If you want to use Django with a database, which is probably the case, you'll
also need a database engine. PostgreSQL_ is recommended, because we're
PostgreSQL fans, and MySQL_, `SQLite 3`_, and Oracle_ are also supported.

Do I lose anything by using Python 2.4 versus newer Python versions, such as Python 2.5 or 2.6?
-----------------------------------------------------------------------------------------------

Not in the core framework. Currently, Django itself officially supports any
version of Python from 2.4 through 2.7, inclusive. However, newer versions of
Python are often faster, have more features, and are better supported.
Third-party applications for use with Django are, of course, free to set their
own version requirements.

Over the next year or two Django will begin dropping support for older Python
versions as part of a migration which will end with Django running on Python 3
(see below for details).

All else being equal, we recommend that you use the latest 2.x release
(currently Python 2.7). This will let you take advantage of the numerous
improvements and optimizations to the Python language since version 2.4, and
will help ease the process of dropping support for older Python versions on
the road to Python 3.

Can I use Django with Python 2.3?
---------------------------------

Django 1.1 (and earlier) supported Python 2.3. Django 1.2 and newer does not.
We highly recommend you upgrade Python if at all possible, but Django 1.1 will
continue to work on Python 2.3.

Can I use Django with Python 3?
-------------------------------

Not at the moment. Python 3.0 introduced a number of
backwards-incompatible changes to the Python language, and although
these changes are generally a good thing for Python's future, it will
be a while before most Python software catches up and is able to run
on Python 3.0. For larger Python-based software like Django, the
transition is expected to take at least a year or two (since it
involves dropping support for older Python releases and so must be
done gradually).

In the meantime, Python 2.x releases will be supported and provided
with bug fixes and security updates by the Python development team, so
continuing to use a Python 2.x release during the transition should
not present any risk.

Will Django run under shared hosting (like TextDrive or Dreamhost)?

Should I use the stable version or development version?
-------------------------------------------------------

Generally, if you're using code in production, you should be using a
stable release. The Django project publishes a full stable release
every nine months or so, with bugfix updates in between. These stable
releases contain the API that is covered by our backwards
compatibility guarantees; if you write code against stable releases,
you shouldn't have any problems upgrading when the next official
version is released.
