+# GPIO Via Golang
+
+Ok, we are going to try the golang periph library with this.
+
+## Periph Library
+
+The Periph library is broken up into a number of sub libraries that are imported as needed. This allows the developers to decouple board implementations from drivers and devices.
+
+
+```bash
+go get periph.io/x/host/v3
+go get periph.io/x/conn/v3
+```
