+    Detect improperly formatted Markdown code blocks and suggest proper formatting.
+
+    There are four basic ways in which a code block is considered improperly formatted:
+
+    1. The code is not within a code block at all
+        * Ignored if the code is not valid Python or Python REPL code
+    2. Incorrect characters are used for backticks
+    3. A language for syntax highlighting is not specified
+        * Ignored if the code is not valid Python or Python REPL code
+    4. A syntax highlighting language is incorrectly specified
+        * Ignored if the language specified doesn't look like it was meant for Python
+        * This can go wrong in two ways:
+            1. Spaces before the language
+            2. No newline immediately following the language
+
+    Messages or code blocks must meet a minimum line count to be detected. Detecting multiple code
+    blocks is supported. However, if at least one code block is correct, then instructions will not
+    be sent even if others are incorrect. When multiple incorrect code blocks are found, only the
+    first one is used as the basis for the instructions sent.
+
+    When an issue is detected, an embed is sent containing specific instructions on fixing what
+    is wrong. If the user edits their message to fix the code block, the instructions will be
+    removed. If they fail to fix the code block with an edit, the instructions will be updated to
+    show what is still incorrect after the user's edit. The embed can be manually deleted with a
+    reaction. Otherwise, it will automatically be removed after 5 minutes.
+
+    The cog only detects messages in whitelisted channels. Channels may also have a cooldown on the
+    instructions being sent. Note all help channels are also whitelisted with cooldowns enabled.

-    A simplified interface for a Redis connection.
-
-    We implement several convenient methods that are fairly similar to have a dict
-    behaves, and should be familiar to Python users. The biggest difference is that
-    all the public methods in this class are coroutines, and must be awaited.
-
-    Because of limitations in Redis, this cache will only accept strings and integers for keys,
-    and strings, integers, floats and booleans for values.
-
-    Please note that this class MUST be created as a class attribute, and that that class
-    must also contain an attribute with an instance of our Bot. See `__get__` and `__set_name__`
-    for more information about how this works.
-
-    Simple example for how to use this:
-
-    class SomeCog(Cog):
-        # To initialize a valid RedisCache, just add it as a class attribute here.
-        # Do not add it to the __init__ method or anywhere else, it MUST be a class
-        # attribute. Do not pass any parameters.
-        cache = RedisCache()

-

-            # we access self.cache through an _instance_ of this class.
-            #
-            # For example, attempting to use SomeCog.cache will _not_ work,
-            # you _must_ instantiate the class first and use that instance.
-            #
-            # Now we can store some stuff in the cache just by doing this.
-            # This data will persist through restarts!
