+# = Introduction
+#
+# This document describes all commands currently supported by QMP.
+#
+# Most of the time their usage is exactly the same as in the user Monitor, this
+# means that any other document which also describe commands (the manpage,
+# QEMU's manual, etc) can and should be consulted.
+#
+# QMP has two types of commands: regular and query commands. Regular commands
+# usually change the Virtual Machine's state someway, while query commands just
+# return information. The sections below are divided accordingly.
+#
+# It's important to observe that all communication examples are formatted in
+# a reader-friendly way, so that they're easier to understand. However, in real
+# protocol usage, they're emitted as a single line.
+#
+# Also, the following notation is used to denote data flow:
+#
+# Example:
+#
+# | -> data issued by the Client
+# | <- Server data response
+#
+# Please, refer to the QMP specification (docs/qmp-spec.txt) for
+# detailed information on the Server command and response formats.
+#
+# = Stability Considerations
#
-# QAPI Schema
+# The current QMP command set (described in this file) may be useful for a
+# number of use cases, however it's limited and several commands have bad
+# defined semantics, specially with regard to command completion.
+#
+# These problems are going to be solved incrementally in the next QEMU releases
+# and we're going to establish a deprecation policy for badly defined commands.
+#
+# If you're planning to adopt QMP, please observe the following:
+#
+# 1. The deprecation policy will take effect and be documented soon, please
+# check the documentation of each used command as soon as a new release of
+# QEMU is available
+#
+# 2. DO NOT rely on anything which is not explicit documented
+#
+# 3. Errors, in special, are not documented. Applications should NOT check
+# for specific errors classes or data (it's strongly recommended to only
+# check for the "error" key)
