+You can build and install `icingadb` as follows:

+
+This should place the `icingadb` binary in your configured `$GOBIN` path which defaults to `$GOPATH/bin` or
+`$HOME/go/bin` if the `GOPATH` environment variable is not set.
+
+## Build from Source

+```bash
+go build -o icingadb cmd/icingadb/main.go
