 # Debian-CD-Scripts
 A set of simple scripts for modifying and working with the Debian installer CDs.
+
+This repo is divided into i386 and amd64 versions as the CDs use different directories, though the process aside from that is the same.
+
+## Dependancies
+ - rsync
+ - cpio
+ - genisoimage (cdrkit)
+
+## Usage
+`./extractcd.sh debian-8.2.0-i386-netinst.iso`  
+To extract a CD into the cd/ directory
+
+`./extractrd.sh`  
+To extract an init RAMdisk into the irmod/ directory
+
+`./genrd.sh`
+To convert the irmod directory back into a RAMdisk in the cd/ directory
+
+`./gencd.sh custom.iso`  
+To convert the cd/ directory back into a CD image for use.
