+#############################
+Upgrading from 2.1.0 to 3.0.0
+#############################
+
+.. note:: These upgrade notes are for a version that is yet to be released.
+
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace all files and directories in your "system" folder and replace
+your index.php file. If any modifications were made to your index.php
+they will need to be made fresh in this new one.
+
+Step 2: Change References to the SHA Library
+============================================
+
+The previously deprecated SHA library has been removed in CodeIgniter 3.0.
+Alter your code to use the native `sha1()` PHP function to generate a sha1 hash.
+
+Additionally, the `sha1()` method in the :doc:`Encryption Library <libraries/encryption>` library has been removed.
+
+
+.. note:: If you have any custom developed files in these folders please
+ make copies of them first.
