+Fixing the ImportError related to ``libmkl_rt.so.2``
+============================================================
+
+You may encounter the following ImportError when you try to run a RMG test job ::
+
+    Traceback (most recent call last):
+      File "/PATH-TO-YOUR-ANACONDA/envs/rmg_env/bin/rmg.py", line 48, in <module>
+        from rmgpy.rmg.main import RMG, initialize_log, process_profile_stats, make_profile_graph
+      File "/PATH-TO-YOUR-ANACONDA/envs/rmg_env/lib/python3.7/site-packages/rmgpy/rmg/main.py", line 51, in <module>
+        from cantera import ck2cti
+      File "/PATH-TO-YOUR-ANACONDA/envs/rmg_env/lib/python3.7/site-packages/cantera/__init__.py", line 4, in <module>
+        from ._cantera import *
+    ImportError: libmkl_rt.so.2: cannot open shared object file: No such file or directory
+
+where ``PATH-TO-YOUR-ANACONDA`` is the path to the ``Anaconda3`` directory installed on your machine.
+The default install location of Anaconda on Linux is ``/home/<your_username>/Anaconda3``.
+
+To fix this issue, simply copy ``libmkl_rt.so.1`` as ``libmkl_rt.so.2`` under the rmg environment library by typing the following
+line on your terminal::
+
+    cp /PATH-TO-YOUR-ANACONDA/envs/rmg_env/lib/libmkl_rt.so.1 /PATH-TO-YOUR-ANACONDA/envs/rmg_env/lib/libmkl_rt.so.2
+
+Note that ``PATH-TO-YOUR-ANACONDA`` needs to be the path to your ``Anaconda3`` directory, which mostly likely looks
+like ``/home/<your_username>/Anaconda3``. If you are unable to locate the ``libmkl_rt.so.1`` file on your computer, you can find its location with the following command::
+
+    locate libmkl_rt.so.1
+
+After copying the file as ``libmkl_rt.so.2``, try running the RMG test job again::
+
+    rmg.py input.py
+
+You will see a line saying ``MODEL GENERATION COMPLETED`` on your terminal if your RMG test job ran successfully.
