Getting Started Guide

Depending on your server configuration (which you don't always have a
hand at), you'll need to both "Read" and "Execute" columns of boxes
checked, and at least the "Owner" and "Group" rows for the "Write"
column. Some host might require you to have the public "Write" box
checked, but be careful with that: have anyone be able to edit the content
of your folder is rarely a good thing.
For folders that the installer is needing a recursive permission change on,
you can check the "Recurse in subdirectories" box.
Regularly check that you have made the correct check by relaunching the
installer's compatibility checks: click "Refresh these settings" as often as
necessary.
Once all indicators are green, you can click "Next". If you cannot have
them all green, at least make sure the installer displays "Your
configuration is valid, click next to continue!"

database server is, and which database it should use, along with a few
other details.
