+# Project-specific preferences
+
 You can provide users with a set of project-specific preferences, controlled via a web interface.
 These preferences are stored in XML, in a field of the user table.
-You determine the structure of this XML, and what it's used for.
-On the client, the XML is passed to your application in the [APP_INIT_DATA structure](BasicApi#Communicatingwiththecoreclient).
-
-Examples of project-specific preferences include:
-
-* Graphics preferences: e.g., color scheme.
-* [Application selection](AppFiltering): you can allow users to select which of your applications they will be sent work for.
-
-The PHP code related to project-specific preferences is in `html/project/project_specific_prefs.inc`.
+The code related to project-specific preferences is in `html/project/project_specific_prefs.inc`.
 When you create your project, this is initialized to sample code.

+The sample code contains a number of preferences that you can enable
+by setting the corresponding constant to true in your html/project/project.inc:
+
+* APP_SELECT_PREFS:
+   [Application selection](AppFiltering): users can select which of your applications they will be sent work for.
+* MAX_JOBS_PREFS: users can limit the number of this project's jobs in progress
+* MAX_CPUS_PREFS: users can limit the number of CPUs used by this project.
+* NON_GRAPHICAL_PREF: users can choose to run non-graphical versions of apps if available.
+* COLOR_PREFS: let the user select a color scheme for your application graphics.
+  (On the client, the XML is passed to your applications in the [APP_INIT_DATA structure](BasicApi#Communicatingwiththecoreclient);
+  your graphics app can parse this and changes it colors accordingly).
+* GFX_CPU_PREFS: the user can limit the % of CPU used by the graphics app.
