+#############################
+Upgrading from 2.0.0 to 2.0.1
+#############################
+
+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.
+
+.. note:: If you have any custom developed files in these folders please
+	make copies of them first.
+
+Step 2: Replace config/mimes.php
+================================
+
+This config file has been updated to contain more mime types, please
+copy it to application/config/mimes.php.
+
+Step 3: Check for forms posting to default controller
+=====================================================
+
+The default behavior for form_open() when called with no parameters
+used to be to post to the default controller, but it will now just leave
+an empty action="" meaning the form will submit to the current URL. If
+submitting to the default controller was the expected behavior it will
+need to be changed from::
+
+	echo form_open(); //<form action="" method="post" accept-charset="utf-8">
+
+to use either a / or base_url()::
+
+	echo form_open('/'); //<form action="http://example.com/index.php/" method="post" accept-charset="utf-8"> echo form_open(base_url()); //<form action="http://example.com/" method="post" accept-charset="utf-8">
+
