 ### Add/Modify metrics
 If `nsd` has a new version with new metrics or you want to change the description of the existing metrics, you can make changes to the metrics that `nsd_exporter` emits by using your own metrics config file.
 
 1. Download the metrics config from [`config/config.yaml`](https://raw.githubusercontent.com/optix2000/nsd_exporter/master/config/config.yaml)
 2. Make any additions or modifications you want.
-3. Load it by running `nsd_exporter -metric-config my-custom-config.yaml`. This will use your config instead of the internal metrics config file.
+3. Load it by running `nsd_exporter --metrics-config my-custom-config.yaml`. This will use your config instead of the internal metrics config file.
 
 ## Building
-### Making config changes
-This is only needed if you want to modify the embedded metric configuration file.
 
-Install go-bindata.
 ```
-go install github.com/go-bindata/go-bindata/go-bindata@latest
+make
 ```
-Make any metric config modifications to `config/config.yaml`.
-
-Run `go generate` to generate a new embedded config file. Don't forget to check it in.
