+## Installation and testing of python packages notes

+The `install_log.txt` contains all the steps used to set up the VM used at the RSE18 conference (apt installs, conda install etc) - you can use it outwith the conference to replicate the environment used there.
+
+The `package-list.txt` lists all the conda packages installed in the environment.
+
+The tests to check the packages are working correctly are in the `test_workshop_VM` folder
+
+ - Run the script `run_all_workshop_tests.sh` from that directory.
+ - They can also be run individually from within each subdirectory if needed.
+ - The full correct outputs are in `test_correct_ouput_log.txt`
+ - There should be no Python tracebacks or import errors if everything runs correctly.
