 Development Tools
 =================
 
-See the ``/test`` folder in global-workflow for available development and testing tools.
+Two sets of testing are available for use by developers.  The first is the capability to run continuous integration tests locally and the second are a set of comparison tools.
+
+---------------------------
+Continuous Integration (CI)
+---------------------------
+
+The global workflow comes fitted with a suite of system tests that run various types of workflow.  These tests are commonly run for pull requests before they may be merged into the develop branch.  At a minimum, developers are expected to run the CI test(s) that will be impacted by their changes on at least one platform.
+
+The commonly run tests are written in YAML format and can be found in the ``ci/cases/pr`` directory.  The ``workflow/generate_workflows.sh`` tool is available to aid running these cases.  See the help documentation by running ``./generate_workflows.sh -h``.  The script has the capability to prepare the EXPDIR and COMROOT directories for a specified or implied suite of CI tests (see :doc:`setup` for details on these directories).  The script also has options to automatically build and run all tests for a given system (i.e. GFS or GEFS and a placeholder for SFS).  For instance, to build the workflow and run all of the GFS tests, one would execute
+
+::
+
+    cd workflow
+    ./generate_workflows.sh -A "your_hpc_account" -b -G -c /path/to/root/directory
+
+where:
+
+    * ``-A`` is used to specify the HPC (slurm or PBS) account to use
+    * ``-b`` indicates that the workflow should be built fresh
+    * ``-G`` specifies that all of the GFS cases should be run (this also influences the build flags to use)
+    * ``-c`` tells the tool to append the rocotorun commands for each experiment to your crontab
+
+More details on how to use the tool are provided by running ``generate_workflows.sh -h``.

 The sequence of jobs that are run for an end-to-end (analysis+forecast+post processing+verification) GFS configuration using the Global Workflow is shown above. The system utilizes a collection of scripts that perform the tasks for each step.
 
-For any cycle the system consists of two suites -- the "gdas" suite which provides the initial guess fields, and the "gfs" suite which creates the initial conditions and forecast of the system. As with the operational system, the gdas runs for each cycle (00, 06, 12, and 18 UTC), however, to save time and space in experiments, the gfs (right side of the diagram) is initially setup to run for only the 00 UTC cycle (See the "run GFS this cycle?" portion of the diagram). The option to run the GFS for all four cycles is available (see the ``gfs_cyc`` variable in configuration file).
