 # CCS (Complete Corresponding Source) Requirements
 
-As a Free Software project, libreCMC works to go above and
-beyond its license obligations to be a good neighbor and to
-promote the ideals of Free Software. The project was founded
-on the idea that everyone should have the *freedom* to control
-the hardware they own, which means being able to fully control
-what it does and what runs on it. To ensure that everyone continues
-to have this freedom, a mechanism was added to the build system [1]
-to generate a CCS disk which OEMs and others would be able to
-distribute with devices for compliance and to push the idea that
-sources should be provided with a device at the time of sale.

+compliant if the disk is handed off with the device.

 ## `make ccsdisk`
 
-A new target was created to build a CCS disk based upon the option of upstream
-sources or to use a local checkout. As it stands, this includes everything except
-for u-boot sources for a given target. In the near future, the libreCMC project
-will start including versions of u-boot for all offically supported targets and
-going forward a requirement for offical hardware support will be u-boot in libreCMC.
+A new target was created to build a CCS disk based upon the option of using a
+external repository or to use a local checkout. As it stands, this includes
+everything except for u-boot sources for a given target. In the near future, the
+libreCMC project will start including versions of u-boot for all officially
+supported targets and, going forward, make this a requirement for official
+hardware in libreCMC.
+
+
+## How to use
+
+There are two ways to use CCS disk : enable "Build the libreCMC CCS Disk" during
+image configuration or run `make ccsdisk` after all desired firmware images have
+been built. Since u-boot for a given target most likely is missing, it's
+important that the sources for u-boot be packaged and included on the disk. To
+do this, make sure they are included in `target/ccsdisk/files` with proper
+documentation. To make things a little bit easier, enabling the toolchain option
+during image configuration and using the toolchain to build u-boot will make
+things go much easier if it can be done.
