Unable to install from source

Hello everyone here,
I want to install jitsi from the source but I am getting a breaking link to the page with the source file. Based on the documentation, I should find the current stable release here

Since I could not find, I downloaded and Installed the videobridge .deb from the main site

However, I get lost where I need to run the videobridge using the command
./jvb.sh --host=localhost --domain=jitsi.example.com --port=5347 --secret=YOURSECRET1

as described in the documentation here

Hello, any help ?

Thank you

when installed from deb packages jvb.sh is in /usr/share/jitsi-videobridge
you can check all the installed files from the package with
dpkg -L jitsi-videobridge2
