<p class="dbconf mysql pgsql">
Please make sure the database you have chosen exists and is empty.<br>
The username provided must have access to create tables within the database.
</p>
<p class="dbconf sqlite">
For SQLite the database name will be a filename on disk, relative to
where shimmie was installed.
</p>
<p class="dbconf none">
Drivers can generally be downloaded with your OS package manager;
for Debian / Ubuntu you want php-pgsql, php-mysql, or php-sqlite.
