+OpenFPGA shortcuts
+------------------
+
+OpenFPGA provides bash/zsh shell-based shortcuts to perform all essential functions and navigating through the directories. Go to the OpenFPGA directory and source ``openfpga.sh``
+
+.. code-block:: bash
+
+   cd ${OPENFPGA_PATH} && source openfpga.sh
+
+.. note::
+    The OpenFPGA shortcuts are designed to work with only bash based shells. e.g. bash/zsh/fish etc.
+
+Shortcut Commands
+^^^^^^^^^^^^^^^^^
+
+Once the ``openfpga.sh`` script is sourced, you can run any of the following commands directly in the terminal.
+
+.. option:: list-tasks
+
+   This command lists all the OpenFPGA tasks from the current task directory.
+   default task directory is considered as ``${OPENFPGA_PATH}/openfpga_flow/tasks``
+
+.. option:: run-task <task_name> **kwarags
+
+   This command runs the specified task listed from the ``list-task`` command or from the existing directory. The command name is relative to the ``TASK_DIRECTORY``. User can provide any additional arguments which are listed `here <_openfpga_task_args>`_ to this command.
+
+.. option:: run-modelsim
+
+   This command runs the verification using ModelSim.
+   The test benches are generated during the OpenFPGA run.
+   **Note**: user need to have ``VSIM`` install and configured
+
+
+.. option:: run-regression-local
+
+   This script runs the regression test locally using the current version of OpenFPGA.
+   **NOTE** Important before making a pull request to the master
