 ------------------------
 
 1. Make sure you have the development dependencies installed
-2. Place GTFS .zip files, OSM files, and elevation .tif files (optional) in the otp_data folder
-3. Copy `deployment/ansible/group_vars/development_template` to `deployment/ansible/group_vars/development`
-4. Change into the `src/` folder and run `npm install` to install the node modules on the host machine
-5. Run `vagrant up`
-6. See the app at http://localhost:8024! See OpenTripPlanner at http://localhost:9090.
-7. Running `./scripts/serve-js-dev.sh` on the host will rebuild the front-end app on file change (the browser must be reloaded manually to pick up the change). Alternatively, `cd /opt/app/src && npm run gulp-development` can be run manually in the VM to pick up changes to the static files.
+2. Place GTFS .zip files, OSM files, and elevation .tif files (optional) in the root of the otp_data folder
+3. Generate a graph file with (takes approx 3 hours) `docker-compose run --rm otp otp --build /var/otp` in the deployment/graph directory.
+4. Copy `deployment/ansible/group_vars/development_template` to `deployment/ansible/group_vars/development`
+5. Change into the `src/` folder and run `npm install` to install the node modules on the host machine
+6. Run `vagrant up`

 Note that if there is an existing build Graph.obj in `otp_data`, vagrant provisioning in development mode will not attempt to rebuild the graph, but will use the one already present.
