Bromine is a web-based application written in php/mysql.
As such you will need a web-server with php/mysql running. If you're new to this we recommend xampp

Once installed we need to edit the php.ini
As you might know, selenium tests can take a long time, so we need to set max_execution_time to a suitable high number.

if using xampp php.ini is located at xampp\apache\bin\

edit: max_execution_time = xxxxxx ; Maximum execution time of each script, in seconds
Where xxxx is a suitable high number.'

As of version b.1.9.0.2 you'll also need to set:
short_open_tags = On

For mysql you need to have a user with access to create and modify tables. if using xampp you can do this with phpMyAdmin. Open xamppurl/phpMyAdmin and configure an user. If installed locally xamppurl is localhost.

All done.
