To install Koha for immediate use we recommend
- A Linux server – Debian is what most people use
- Root access to the server
- A better than average level of skill with the command line, Apache, and MySQL tools
Koha is free software and is licensed under the GNU General Public License, either version 3 of the License, or (at your option) any later version.
There are often two versions of Koha being released here during the same period of time: one is the current release and the other is the previous release. The current release is 3.10, and the previous releases still being supported are 3.6 and 3.8.
