Installing with SetupTools
If you have SetupTools installed on your system, use the standard method of installing python packages for your system (see easy_install docs). On most systems run the following as a root/admin user:
easy_install markdown
Manual Installation
Download the source from PyPI or a SourceForge mirror.
On Windows, simply run the installer.
On all other systems, extract the files. If you want to install markdown as a module into your python tree, from the directory where you unpacked the files run:
sudo python setup.py install
You typically need to be root to install modules this way - hence the use of "sudo". If you don't have root access, it probably doesn't make sense for you to "install" markdown this way - just put the markdown.py file somewhere and make sure that directory is on your PYTHONPATH.
Now what?
If you want to use markdown as a command-line tool, please proceed to Command Line. If you want to use it as a module, go to Using as a Module. If you want to use it with some of the popular frameworks (e.g., Django) or wikis (e.g., MoinMoin), go to Integration.
