SSRS Configurations to build the Reports

Hello Friends,
We have finished installation of Sql Server Reporting Server 2017 and setup reporting URL but installing first time so need to know the next steps so we can start to build up the Reports and user can use it.We have currently RepotServers and ReprotServerTemp Database created during installation process. If you can guide the completely setup process for SSRS so we can use it to build and configure different reports, publishing it to web url for user can view, user and folders access so user can start to build their own reports too and other steps we can follow.

Thanks for help!
