These are few ways I modify the code, if needed, in SuiteCRM:

• SuiteCRM User Guide: this guide is well written and maps the way to learn about the system as a user and as a developer.
  • https://docs.suitecrm.com/user

• I joined the SuiteCRM Community: Here I learn a lot of helpful information from developers who have been dealing with the same issues I encounter.
  • https://community.suitecrm.com/invites/QtsSmkJLHW

• I have studied the 215 database tables in SuiteCRM and recreated a map to understand how they are related to each other, the fields, properties and data types.

• I am constantly mastering small skills. For instance, when I started the first challenge was making installations and upgrading by downloading the zip file from the SuiteCRM page. I did it over and over until I got it right.

• I learnt about folders and files structures, permissions, backup, cron jobs, modules

• I play with the code and try to understand how PHP and Angular is used.

IN CONCLUSION

Above all I am a user for my own business which creates the need to learn new functionalities in SuiteCRM.
