Drone comes in two flavours:
- a zip archive that contains everything to get it running both as a web application or as a standalone bot:
- a war archive that can be used as a web application with an existing servlet container:
standalone zip archive
You can just unzip this archive at the directory of your choice, nothing more is required.
This web application archive has to be deployed in your servlet container. Since the configuration files are inside the archive, it's best to install it as an unpacked web application and edit the files directly. You can of course also unpack the war file, modify the configuration files and create a new war file that can be deployed as usual.
