@@ -2,17 +2,27 @@ This is an Apple II port of **Conway's Game of Life**.
 
 It should build with no modification on Linux, macOs and Windows 10 (using the bash).
 
+---
+
 Two binaries will be produced.
+
 1. *gol.out* is a Linux executable.
 2. *gol.a2* is an Apple II executable
 
 **Prerequisite in order to build:**
+
 * The [cc65 compiler suite](https://github.com/cc65/cc65), with the environment variable *CC65_HOME* set to its folder
 
-**How to make a disc image**
-In order to embed the Apple II executable into a disc image, you can use [*AppleCommander*](http://applecommander.sourceforge.net/).
+**Prerequisite in order to produce the disk image**
 
->java -jar [APPLECOMMANDER_PATH] -cc65 disc.dsk GOL BIN < gol.a2
+* Java Runtime
+* [*AppleCommander*](http://applecommander.sourceforge.net/)
+
+**Embedding the Apple 2 binary into the disk image**
+
+Run the *add-to-disk.sh* script.
