+    -- after downloading the mojo model from h2o3, the following packages
+       are needed to execute the model to do batch or real-time scoring
+
+    Make all packages available on your machine:
+
+    sudo apt-get -y update
+
+    Install Java to include open source H2O-3 algorithms:
+    
+    sudo apt-get -y install openjdk-8-jdk
+
+    Install Datatable and pandas:
+
+    pip install datatable
+    pip install pandas
+
+    Option 1: Install H2O-3 with conda
+
+    conda create -n h2o3-nifi-minifi python=3.6
+    conda activate h2o3-nifi-minifi
+    conda config --append channels conda-forge
+    conda install -y -c h2oai h2o
+
+    Option 2: Install H2O-3 with pip
+
+    pip install requests
+    pip install tabulate
+    pip install "colorama>=0.3.8"
+    pip install future
+    pip uninstall h2o

Review comment:
       the uninstall line is there in case a user has an older version of h2o, then they uninstall it, and install the latest version of h2o. Yes this instruction is from the directions of H2O-3.
