[solved] How can I get zigbee binding?

It seems zigbee binding PR is still open.

So it is NOT in openhab2-addons git repo yet. However, when I go to cdjackson/openhab2-addons:zigbee which is shown in above page, there is NOT a zigbee branch there either.

0 Have I made some mistake here?
1 where can I get zigbee binding git repo, either within openhab2-addons or separate git repo? OR
Should I wait some time for that?

Thank you very much.

Never mind. I found zigbee branch in cdjackson’s git repo.
