A new documentation is available for Squash TM 2.0 and later versions, check it here
Squash TM comes by default with an embedded H2 database, and was configured to use it, but this is for test purposes only.
To use Squash TM in production, it is recommended to use either a MySQL or a PostgreSQL database.
Follow the links below to switch to MySQL or PostgreSQL.
Caution : by switching to a MySQL or PostgreSQL database, all data previously entered in the embedded database will be lost.
