Copy the sample environment files and edit them to suit your needs.
```sh
cp .env.sample .env
cp docker-compose.yml.sample docker-compose.yml
```
Start the service with docker:
```sh
docker-compose up -d
```
...*or* start the service directly, or with a daemon manager:
```sh
npm run start
```
The API should now be listening on port 8080 or whatever you set in the `docker-compose.yml`. You may choose to run this through a proxy server or whatever.
## Serving the clientside app
You can use the contact form in `index.html.sample`. Tweak it to your needs and put it in your clientside code. I'm not offering support for your particular set up, but the code in both `index.html.sample` and `index.js` is short and easy to modify to your use case.
