+# Additional Projects
+
+DevStack has a hook mechanism to call out to a dispatch script at specific points in the execution if `stack.sh`, `unstack.sh` and `clean.sh`.  This allows higher-level projects, especially those that the lower level projects have no dependency on, to be added to DevStack without modifying the scripts.  Tempest is built this way as an example of how to structure the dispatch script, see `extras.d/80-tempest.sh`.  See `extras.d/README.md` for more information.

+# Local Configuration
+
+Historically DevStack has used ``localrc`` to contain all local configuration and customizations. More and more of the configuration variables available for DevStack are passed-through to the individual project configuration files.  The old mechanism for this required specific code for each file and did not scale well.  This is handled now by a master local configuration file.
+
+# local.conf
+
+The new config file ``local.conf`` is an extended-INI format that introduces a new meta-section header that provides some additional information such as a phase name and destination config filename:
+
+  [[ <phase> | <filename> ]]
+
+where <phase> is one of a set of phase names defined by ``stack.sh`` and <filename> is the project config filename.  The filename is eval'ed in the stack.sh context so all environment variables are available and may be used.  Using the project config file variables in the header is strongly suggested (see example of NOVA_CONF below).  If the path of the config file does not exist it is skipped.
+
+The defined phases are:
+
+* local - extracts ``localrc`` from ``local.conf`` before ``stackrc`` is sourced
+* post-config - runs after the layer 2 services are configured and before they are started
+* extra - runs after services are started and before any files in ``extra.d`` are executes
+
+The file is processed strictly in sequence; meta-sections may be specified more than once but if any settings are duplicated the last to appear in the file will be used.
+
+  [[post-config|$NOVA_CONF]]
+  [DEFAULT]
+  use_syslog = True
+
+  [osapi_v3]
+  enabled = False
+
+A specific meta-section ``local:localrc`` is used to provide a default localrc file.  This allows all custom settings for DevStack to be contained in a single file.  ``localrc`` is not overwritten if it exists to preserve compatability.
+
+  [[local|localrc]]
+  FIXED_RANGE=10.254.1.0/24
+  ADMIN_PASSWORD=speciale
+  LOGFILE=$DEST/logs/stack.sh.log
+
+Note that ``Q_PLUGIN_CONF_FILE`` is unique in that it is assumed to _NOT_ start with a ``/`` (slash) character.  A slash will need to be added:
+
+  [[post-config|/$Q_PLUGIN_CONF_FILE]]

+# Extras Hooks
+
+The `extras.d` directory contains project dispatch scripts that are called
+at specific times by `stack.sh`, `unstack.sh` and `clean.sh`.  These hooks are
+used to install, configure and start additional projects during a DevStack run
+without any modifications to the base DevStack scripts.
+
+When `stack.sh` reaches one of the hook points it sources the scripts in `extras.d`
+that end with `.sh`.  To control the order that the scripts are sourced their
+names start with a two digit sequence number.  DevStack reserves the sequence
+numbers 00 through 09 and 90 through 99 for its own use.
+
+The scripts are sourced at each hook point so they should not declare anything
+at the top level that would cause a problem, specifically, functions.  This does
+allow the entire `stack.sh` variable space to be available.  The scripts are
+sourced with one or more arguments, the first of which defines the hook phase:
+
+arg 1: source | stack | unstack | clean
+
+    source: always called first in any of the scripts, used to set the
+        initial defaults in a lib/* script or similar
+
+    stack: called by stack.sh.  There are three possible values for
+        the second arg to distinguish the phase stack.sh is in:
+
+        arg 2:  install | post-config | extra
+
+    unstack: called by unstack.sh
+
+    clean: called by clean.sh.  Remember, clean.sh also calls unstack.sh
+        so that work need not be repeated.
