You need to have your yarn's resource manager deployed, and execute YarnVision code on a machine that can reach your resource manager

How to run locally

1. Install Node.js and npm
2. Checkout this repo to a folder like YarnVision
3. run npm install && npm run build
4. run server.js and provide (a list of) address of your resource manager in the commandline arguments, like node server.js http://my-yarn-resourcemanager.location:<port> http://my-other-yarn-resourcemanager.location:<port>
5. open http://localhost:3000
