+## Building
+
+### Building without WebUI
+
+Simply run `go build` in the project directory.
+
+### Building with WebUI
+
+Make sure you have NodeJS and Yarn installed.
+
+Then run the following commands:
+
+1. `go generate ./...` - This will build the webui react project.
+2. `go build -tags withUI` - This will build the binary with included UI.
