To start playing with Hatta, you just have download the executable file, and run it with Python. The file is an archive, that already contains all the python modules that Hatta requires.
Alternatively, if you have Hatta installed as a python module using
easy_install or from your operating system package, you can run the standalone server with the command
python -m hatta.
It will create a directory
docs and a Mercurial repository inside it.
The server will by default run on port 8080 on all your interfaces, so you can access it by typing
http://localhost:8080 in your web browser.
You can change these defaults, see Script settings.
