To use the package you must have installed Python first. I recommend PythonXY, since this package already comes with a lot of useful add on packages. There are two options to install pylibics. First by installing the precompiled package using setuptools or by compiling the package yourself. In most cases you don't want to compile the package yourself but install the precompiled ones.
Installing the precompiled package on Windows
Open a command prompt and type (C:\> is the prompt, "easy_install pylibics" is the command):
C:\> easy_install pylibics
or if you want to upgrade to a newer release
C:\> easy_install -U pylibics
This should then give you some output like this
C:\> easy_install pylibics

That's it. You can now import the package in Python. Please see the documentation and example for further instructions.
If you don't have the easy_install command available you will have to install setuptools.
Compiling the package
To compile the package yourself go to the download section and download the source code first. Compiling the package requires Visual Studio (Windows) or g++ (Linux) and SWIG. In case you have installed PythonXY with all packages (full installation) you already have SWIG installed. Unpack the source code and follow the compilation instructions in the README file.
