How to add or remove existing Zero instance?

Based on my reading below are steps…

### Node adding:

1. I do not see any instructions, can someone help?

### Node removal:

1. Make sure Zero replica removal node is completely offline
2. On the Zero leader, make a GET request /state  
– make a note of the removal node id from the response
3. On the Zero leader, make a GET request /removeNode?id=ID\_FROM\_STEP#2&group=0

After deleting the alpha node through the zero leader, you need to stop the deleted alpha service, delete the p/ t/ w/ folder, and then restart the alpha service. You can see the new alpha node and the data will be synchronized automatically
