 ## Building and Installing
-At some point I'll include a Makefile, until then manually build and copy to any directory in your path.
+Use the provided make file and then move the binary to your directory choice:
 
 ```shell
-cd cmd/cli
-go build -o ketotrack
-mv ketotrack $HOME/.local/bin
+make
+mv ketotrack ~/.local/bin/
 ```
