 Run Graph Analysis
 =========================
+
+GART supports different approaches for graph analysis. The following sections describe how to run the different analysis methods.
+
+Graph Analysis with GAE
+------------------------
+
+The Graph Analysis Engine (GAE) is a graph analysis framework that provides a set of graph algorithms for analyzing large-scale graphs. GAE is implemented in C++ and provides a Python interface for running graph algorithms on graphs stored in the GART format. The GAE library is included in the GART distribution and can be found in the `gae` directory.
+
+After running the GART server, you can run graph analysis using the GAE library by ``mpirun`` command.
+
+.. code:: bash
+
+    gart-env$ cd /workspace/gart/
+    gart-env$ mpirun -n 1 ./apps/run_gart_app --read_epoch 0 --app_name sssp --sssp_source_label organisation --sssp_source_oid 0 --sssp_weight_name wa_work_from
+
+Other Alternatives
+------------------
+
+Please refer to the `PostgreSQL Extension <pgx.html>`_. The PostgreSQL extension provides a set of graph algorithms that can be run on graphs stored in the GART format.
