+class Context:
+    """Represents the context in which a command is being invoked under.
+
+    This class contains a lot of meta data to help you understand more about
+    the invocation context. This class is not created manually and is instead
+    passed around to commands by passing in :attr:`Command.pass_context`.
+
+    Attributes
+    -----------
+    message : :class:`discord.Message`
+        The message that triggered the command being executed.
+    bot : :class:`Bot`
+        The bot that contains the command being executed.
+    args : list
+        The list of transformed arguments that were passed into the command.
+        If this is accessed during the :func:`on_command_error` event
+        then this list could be incomplete.
+    kwargs : dict
+        A dictionary of transformed arguments that were passed into the command.
+        Similar to :attr:`args`\, if this is accessed in the
+        :func:`on_command_error` event then this dict could be incomplete.
+    command
+        The command (i.e. :class:`Command` or its superclasses) that is being
+        invoked currently.
+    invoked_with : str
+        The command name that triggered this invocation. Useful for finding out
+        which alias called the command.
+    invoked_subcommand
+        The subcommand (i.e. :class:`Command` or its superclasses) that was
+        invoked. If no valid subcommand was invoked then this is equal to
+        `None`.
+    subcommand_passed : Optional[str]
+        The string that was attempted to call a subcommand. This does not have
+        to point to a valid registered subcommand and could just point to a
+        nonsense string. If nothing was passed to attempt a call to a
+        subcommand then this is set to `None`.
