.. _quick-start: *********** Quick Start *********** To get started with GYRE, follow these five simple steps: * install the `MESA Software Development Kit `__; * download the `GYRE source code `__; * unpack the source code using the :command:`tar` utility; * set the :envvar:`GYRE_DIR` environment variable to point to the newly created source directory; * compile and install GYRE using the command :command:`make -j -C $GYRE_DIR`. For a more in-depth installation guide that covers alternative use-cases, refer to the :ref:`installation` chapter. If the code doesn't compile properly, consult the :ref:`troubleshooting` chapter. Otherwise, proceed to the next chapter where you'll put together your first GYRE calculation.
