cant run mutiple wiki.js instance in one server node use node wiki start about wiki-v1 HOT 2 OPEN

You cannot run multiple instances using that command.

You must instead start each instance using node server.

If you want to run them as background tasks (like node wiki start), you must install pm2 globally:
npm install -g pm2.
You can then start each instance using:
pm2 start server/index.js --name wiki1
pm2 start server/index.js --name wiki2
pm2 start server/index.js --name wiki3
etc...

from wiki-v1.

This command pm2 start server/index.js --name wiki1 is not in the docs. It should be specified here https://docs.requarks.io/wiki/install#run-at-startup

Also, It should be nice to specify an option to do not open a node window, like a quiet mode or background.
