Removal candidate creation for uninstallation of Software

Hi All,
Greetings!

We have a requirement , to uninstall software though Removal candidates. Few clarifications required for below points.

*Is there any documents available for configuration

*In one doc it is mentioned like "Removal candidates are also created as part of using remediation options for unlicensed and unallocated software installations".--------is there any automation script available for creation of RC from Remediations options? or every time we need to create it manually ?

*Many Removal candidates have created in our instance with justification 'Restricted software'. I can see those have mentioned as restricted in Software model table. Is the RC creating by any job OR immediately when system detect it after discovery?

*We just installed CSD 2.0, which also imported 'CSD Catalog Item Template'  in maintain items table.  how is this connected with Removal candidates table?

Regards,
