-## Source
+## Bundle
 
 1. Install XCode
-2. Install [Node 12.14.1](https://nodejs.org/en/)
-3. Use [rebuild-wekan.sh script](https://github.com/wekan/wekan/blob/edge/releases/virtualbox/rebuild-wekan.sh) to first install Wekan dependencies and then build Wekan.
-4. Change to Wekan directory: `cd wekan`
-5. Run meteor: `meteor` - this runs node in http://localhost:3000 and mongo at http://localhost:3001 .
-6. In another bash shell, run: `meteor mongo` - this connects to MongoDB CLI
-7. Alternatively, to use custom ports, use for example `meteor --port 4000` that runs node in port 4000 and mongo in next port 4001.
