Installation
Windows (32/64-bit)
The recommended way to install pyspades on Windows is to use the prebuilt binaries. Head over to the Downloads page and get the most recent one and extract it to a preferable path.
If this doesn't work, you should try and install from source.
Linux/OS X/BSD/whatever
On these platforms, you have to install from source. Usually, this involves installing the dependencies (see README.txt) using your package manager, cloning the repository with Mercurial, then running build.sh (build.bat on Windows).
Running
Edit config.txt to your liking. If you don't want to go too deep with the configuration, just edit "name", "map" and the admin password ("replaceme"). To change game modes add a new line to "scripts" containing the game mode you want to play: e.g. "runningman" "tdm" "tc".
On Windows, run run.exe, and on other platforms, run run_server.sh.
Your server should hopefully be running now!
