`adding-removing-qbft-validators` use `istanbul-tools` but didn't mention how to install it about doc.goquorum HOT 2 CLOSED

@baptiste-b-pegasys I had tried to create node-5 with

npx quorum-genesis-tool \
--validators 1 \
--members 0 \
--bootnodes 0 \
--outputPath $tmpdir

And it can add node-5 to validator and start node sucessfully.

You are right, the pre-requisite page has changed with the new genesis tool and not this page, so the istanbul tool is not there.

The old version:
https://consensys.net/docs/goquorum/en/21.10.1/tutorials/private-network/create-qbft-network/

If you have go installed, you can clone the package or download the source code and do a go run or go build on the directory cmd/qbft. If you prefer I can build the binary on the platform you want to.

With the new genesis tool, I am not sure if we can generate one node to a specific directory.
I think you can generate again on another directory with the same genesis tool with one node and move and rename the node directory into the structure, or increase the number of the nodes and copy the latest node directory to your first generated structure.
