 GM announced that they would be releasing the API in 2013. 6 years later they still refuse to respond to developer requests.
 The API has been reverse engineered via decompilation and protocol interception in order to facilitate interoperability. No copywritten works have been duplicated.
 
-To use this API you will require a valid client id and client secret. You may email developer@gm.com to request credentials but they have yet to provide any.
-Alternatively you can extract and decrypt them from the Android .apk file.
+You are accepting all responsibility and liability for the use of this content.
+
+# Client Credentials
+To use this API you will require a valid client id and client secret. The correct approach would be to request access from GM at https://developer.gm.com/ or by emailing them at developer.gm.com.
+
+Alternatively (and because GM refuses to respond to developer requests) you can extract the credentials from the Android app's .apk file.
+I am _NOT_ including the source code for this process, but I have included the capability. GM.SettingsReader.dll can do this. I have obfuscated the process.
+
+IMPORTANT: The demo app requires a copy of the Android app's .apk file to be copied to the "apk" folder. It has been tested with the myChevrolet app, version 3.21.0.
+VERY IMPORTANT: Unless you want an international incident on your hands DO NOT SHARE ANY OF THE CONTENTS OF THE SETTINGS FILE ANYWHERE _EVER_!!!!
 
 
+# TODO
 This is very early, unpolished, incomplete code. No judgement please.
