 ### Available image tags
 
-The developmentseed/geolambda image in Docker Hub has several available tags:
-
-- **base**: The base image consists of an Amazon base image with python added, along with the boto3 and nose libraries. The purpose of the main image is to replicate the base system in Lambda with the nose testing framework added so that a deployable package can be tested on an image like what is used in the Lambda container.
-- **core**: The core image contains system dependencies that are used by other other images. It also defines version numbers for packages that are installed in other images.
-- **min**: GDAL2, with a minimized set of packages/drivers is installed with Python support, along with proj.4
-- **hdf**: GDAL2, with HDF4 and 5 support added (including szip and proj.4)
-- **cloud**: GDAL2, with libraries common for cloud access: GeoTiff and Jpeg2000 (using OpenJPEG)
-- **full**: GDAL2 with all libraries compiled in other images
