With the release of Gather 0.1.7 we have focused on a few areas to reduce friction during installation.
We are introducing the concept of Maintenance Mode in Gather. During startup Gather will enter Maintenance Mode when database configuration is necessary.
For example, as long as you have a MySQL or PostgreSQL database available, the database portion of the installation can be skipped. Upon startup Gather will enter Maintenance Mode and will alert the user that additional configuration needs to be performed. By providing Gather with the super user credentials to your database it is able to create the necessary database schema and bootstrap itself.
