After doing npm install in the root and in the app folder, run npm start in the root
The Aragon client starts, but when you try to go to the Approvals app, it'll say it can't resolve an index.html file
This is because the project has a .gitignore file, that includes build. We manually specify --files app/build during the publish (and run) process, and despite specifying it, the gitignore pattern gets applied and ignores this.
Files specified through --files would override the ignore list.
Files specified through --files are ignored by the .gitignore or .ipfsignore.
Note that we were able to fix this by adding a blank .ipfsignore file (see commit), which is OK, but a bit confusing :).
