 Development Installation
 ------------------------
 
 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. Run `vagrant up`
-5. See the app at http://localhost:8024! See OpenTripPlanner at http://localhost:9090.
-6. 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.
+4. Change into the `src/` folder and run `npm install` to install the node modules on the host machine

 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.

 Building AMIs
 ------------------------
 1. Make a production group_vars file (similarly to how is described above with development). Make sure production is set to true, and also specify an app_username, which should be set to: ubuntu

 3. In the project directory within the app VM, run: `deployment/cac-stack.py create-ami --aws-access-key-id YOUR_ACCESS_KEY --aws-secret-access-key YOUR_SECRET_KEY --aws-role-arn YOUR_ASSUMED_ROLE_ARN`
 4. The previous command builds all AMIs. To only build a single AMI, run the same command, but also specify the `--machine-type` parameter, which may be set to one of: `bastion`, `otp`, or `app`.

 4. Note that database migrations are not automatically run. When the DataPlane is first brought up, it is necessary to manually create the app user/db and run migrations.
 5. Launching a set of Production stacks with the other color (`Green`), will use the same `VPC` and `DataPlane` stacks, but will create different `OtpServer` and `WebServer` stacks (if they don't already exist).
