 Go into the `api/` folder and run `go get -d ./...` to download the dependencies, followed by `go build` to compile the executable.  
 This project is using [Go Modules](https://github.com/golang/go/wiki/Modules), which were introduced with Go v1.11. So, make sure that the project code is outside your `$GOPATH/src`, or set the environment variable `GO111MODULE=on` when running `go get|build|...`.

 Once built the executable can be started with `./api -c=/path/to/config.json`, or, if using env variables, `UNPROCESSED_IMAGES=/path/to/image/dir PORT=3333 DATABASE=tagallery DATABASE_HOST=localhost:27017 ./api`.
