 You can get the dev branch checked out using `git checkout dev`.
 
+Once checked out, install the dependencies using `npm install`, then copy the included `my.env.template`file to `my.env` and edit the file to include your settings (like the Mongo URL). Leave the `NODE_ENV=development` line intact. Once set, run the site using `npm run dev`. This will start Nigthscout in the development mode, with different code packaging rules and automatic restarting of the server using nodemon, when you save changed files on disk. The client also hot-reloads new code in, but it's recommended to reload the the website after changes due to the way the plugin sandbox works.

+If you want to additionaly test the site in production mode, create a file called `my.prod.env` that's a copy of the dev file but with `NODE_ENV=production` and start the site using `npm run prod`.

 - See [install MongoDB, Node.js, and Nightscouton a single Windows system](https://github.com/jaylagorio/Nightscout-on-Windows-Server). if you want to host your Nightscout outside of the cloud. Although the instructions are intended for Windows Server the procedure is compatible with client versions of Windows such as Windows 7 and Windows 10.
 - If you deploy to Windows and want to develop or test you need to install [Cygwin](https://www.cygwin.com/) (use [setup-x86_64.exe](https://www.cygwin.com/setup-x86_64.exe) and make sure to install `build-essential` package. Test your configuration by executing `make` and check if all tests are ok.
