+Mod log has now been separated from Mod for V3.
+
+***********
+Basic Usage
+***********
+
+.. code-block:: python
+
+    from redbot.core import modlog
+    import discord
+
+    class MyCog:
+        @commands.command()
+        @checks.admin_or_permissions(ban_members=True)
+        async def ban(self, ctx, user: discord.Member, reason: str=None):
+            await ctx.guild.ban(user)
+            case = modlog.create_case(
+                ctx.guild, ctx.message.created_at, "ban", user,
+                ctx.author, reason, until=None, channel=None

+**********************
+Registering Case types
+**********************
+
+To register a single case type:
+
+.. code-block:: python
+
+    from redbot.core import modlog
+    import discord
+
+    class MyCog:
+        def __init__(self, bot):
+            ban_case = {
+                "name": "ban",
+                "default_setting": True,
+                "image": ":hammer:",
+                "case_str": "Ban",
+                "audit_type": "ban"
+            }
+            modlog.register_casetype(**ban_case)
+
+To register multiple case types:
+
+.. code-block:: python
+
+    from redbot.core import modlog
+    import discord
+
+    class MyCog:
+        def __init__(self, bot):
+            new_types = [
+                {
+                    "name": "ban",
+                    "default_setting": True,
+                    "image": ":hammer:",
+                    "case_str": "Ban",
+                    "audit_type": "ban"
+                },
+                {
+                    "name": "kick",
+                    "default_setting": True,
+                    "image": ":boot:",
+                    "case_str": "Kick",
+                    "audit_type": "kick"
+                }
+            ]
+            modlog.register_casetypes(new_types)
