+To use this repository, please fork into your own account and then clone onto your system.
 ```bash
 git clone https://github.com/SmithB/pointCollection.git
 ```
-Can then install using `setuptools`
+#### Dependencies
+pointCollection is dependent on some open source programs:
+- [gdal](https://gdal.org/index.html)
+- [pyproj](https://download.osgeo.org/proj)
+- [HDF5](https://www.hdfgroup.org)
+- [netCDF](https://www.unidata.ucar.edu/software/netcdf)
+
+The version of GDAL used within pointCollection will match the version of the installed C program.  The path to the C program that will be used with pointCollection is given by:
+```bash
+gdal-config --datadir
+```
+The pointCollection installation uses the `gdal-config` routines to set the GDAL package version.  
+
+#### Installation
+Can then install using `setuptools`:
 ```bash
 python setup.py install
 ```
-or `pip`
+or `pip`:
 ```bash
 python3 -m pip install --user .
 ```
+Alternatively can install the pointCollection utilities directly from GitHub with `pip`:
+```
+python3 -m pip install --user git+https://github.com/SmithB/pointCollection.git
+```
 Executable versions of this repository can also be tested using [Binder](https://mybinder.org/v2/gh/SmithB/pointCollection/master) and [Pangeo](https://binder.pangeo.io/v2/gh/SmithB/pointCollection/master).
