+## Considerations for Windows
+The tests and test framework are designed to operate from within a unix-like

+
+You will need:
+
+-   Conda
+-   Groovy (v2.4)
+-   Git-Bash
+
+1.  Install [Git for Windows]. This will give you a unix bash-like
+    execution environment
+1.  From within the Git-bash shell navigate to your pipelines project.
+1.  Ensure that you can execute both Python and Groovy from within the
+    Git-Bash shell (i.e. `python --version` and `groovy --version` work)
+1.  From the pipelines project root enter your Conda environment
+    with something like `source activate my-conda-env`. To run the
+    pipelines tests your environment must contain the rdkit package. It
+    can be installed with this command from within Conda...
+
+    $ conda install -c rdkit rdkit
+
+1.  Install additional modules required by `pipelines-utils` but
+    using its requirements file (which can be found in the `pipelines-utils`
+    sub-project): -
+
+    $ pip install -r requirements.txt
