+2. Create a Python environment to use ODC within, we recommend `conda <https://docs.conda.io/en/latest/miniconda.html>`__ as the

+   conda activate odc
 
-   ``python setup.py develop``
+3. Install a develop version of datacube-core.
 
-   Note that the versions must match between GDAL's Python bindings and
-   the native GDAL library. If you receive a gdal error when installing
-   dependencies, you may need to install a specific version first:
+::
 
-   eg. ``pip install gdal==2.0.1``
+   cd datacube-core
+   pip install --upgrade -e .
