i am very new to jitsi, i have no clear idea what are the components of jitsi and how to integrate them in order to get complete details of meetings, user details, meeting room details and all the important component of jitsi. and also the suitable version to install.
Start by following the quick install guide to install and have a running deployment. https://github.com/jitsi/jitsi-meet/blob/master/doc/quick-install.md
Then you can probably have more concrete questions.
After having a running and working deployment you can check the manual install guide where there is step by step instructions and you can have a more clear view of the system: https://github.com/jitsi/jitsi-meet/blob/master/doc/manual-install.md
Do not use manual for installation as it is not recommended, it may be not 100% accurate and there are many steps handled by the default deployment which not-experienced user can miss.
