1. Default Login username : admin password : changeme.
2. change "usr_NeedPasswordChange" to 0 in "user_usr" table because script ask to update password after installation.
3. We have created blank integrityCheck.json file to write integrity check status.
	(Go to Admin -> Edit General settings -> System Settings -> set iIntegrityCheckInterval to 1 and reduce one hour to sLastIntegrityCheckTimeStamp -> Save settings. Now check the file should be created.) This is just to check if this file is needed or not.
4. PHP REQUIREMENT LINK: https://github.com/ChurchCRM/CRM/wiki/Installation or check in {{Path_to_directory}}/vendor/composer/platform_check.php
5. Remove 'DEFINER=`root`@`localhost`' from mysql function
(added since version 2.10.1 , we remove this because it's made again)(Isn't required since 4.1.0)
6. Keep $dbPort = ''; as blank in Config.php post installation, since this was mandatory while installing.
7. In ChurchCRM 5.0.2 we had run the setup manually after renaming Include/Config.php.example to /Include/Config.php and manually entering details and hitting setup URL in browser, as their automated install script had a bug so this turnaround was suggested by one of the developers of the script :

Check in next version if their automated install script works.
