+# Build the binary
+
+This will likely change into some sort of `Makefile` later, but for now what is needed to build and use this utility is to run the followning commands:
+
+```bash
+$ export GOPATH=/home/mock/.local/bin
+$ go build .
+$ convert-epoch -epoch 1631711695
+ Epoch time:   1631711695
+ Local time:   Wed, 15 Sep 2021 09:14:55 -0400
+ Zulu time:    Wed, 15 Sep 2021 13:14:55 +0000
+```
+
+I would like to remove the `-epoch` flag in favor of just assuming an epoch time value, but that will come later too. Gotta keep learning the language.
