-Checkout source code
+### Checkout Source
+Checkout the source code and "cd" into the "scadformat" directory:
 ```bash
 git clone https://github.com/hugheaves/scadformat
+cd scadformat

+#### Build with Make
+If you have GNU Make (or a compatible make utility installed), you can build the program just by running the "make" command:
 ```bash
-cd scadformat
+make
 ```
 
+You should see output similar to the following:
+```

+
+#### Build without Make
+If you don't have make installed (i.e. on Windows), you can still build the program by running the necessary commands manually:

 Generate ANTLR parser
 ```bash
 go generate ./...
 ```
 
 Build the executable
 ```bash
-go build -o scadformat cmd/main.go
+go build -o scadformat cmd/scadformat.go
 ```
 
 run tests
 ```bash
 go test -v ./...
