 Create 'environment' class
 --------------------------
 
+    # This is a PoC of creating the 'environment' class.
+    # For CI tests, please generate your 'inventory.yaml' for step #3 and create
+    # the cookiecutter template based on example template from /examples directory.
+
+    # Below will be used 'cluster' model from 'mcp-baremetal-lab' repo
+    # and the cluster name 'mcp11-ovs-dpdk.local'.
+
     # 1. Create a context file from the current reclass inventory:
 
     reclass-create-inventory-context -d mcp11-ovs-dpdk.local > /tmp/context-mcp11-ovs-dpdk.local.yaml
 
     # 2. Remove existing hardware-related objects from 'cluster', 'system' and 'service' classes:
 
-    reclass-remove-key -r parameters.linux.network.interface /srv/salt/reclass/classes/cluster/physical_mcp11_ovs_dpdk
-    reclass-remove-key -r parameters.linux.network.interface /srv/salt/reclass/classes/system/
-    reclass-remove-key -r parameters.linux.network.interface /usr/share/salt-formulas/reclass/
+    reclass-remove-key parameters.linux.network.interface /srv/salt/reclass/classes/cluster/physical_mcp11_ovs_dpdk
+    reclass-remove-key parameters.linux.network.interface /srv/salt/reclass/classes/system/
+    reclass-remove-key parameters.linux.network.interface /usr/share/salt-formulas/reclass/
 
     # 3. Render the 'environment' class using example template based on cookiecutter:
 
     git clone https://github.com/dis-xcom/reclass_tools ~/reclass_tools
     reclass-render-dir -t ~/reclass_tools/examples/environment -o /tmp/environment -c /tmp/context-mcp11-ovs-dpdk.local.yaml  # You can add multiple YAMLs here
 
-    # 4. Symlink 'environment' to the /srv/reclass/salt/classes
+    # 4. Check that the 'environment' has been created
+
+    tree /tmp/environment/
+
+    # 5. Symlink 'environment' to the /srv/salt/reclass/classes
 
     ln -s /tmp/environment /srv/reclass/salt/classes
 
-    # 5. Add new class '- environment.mcp11-ovs-dpdk.local' to the classes/cluster/<cluster_model>/infra/config.yml
+    # 6. Add new class '- environment.mcp11-ovs-dpdk.local' to the classes/cluster/<cluster_model>/infra/config.yml
+    # (edit the file manually for now)
+
+    # 7. Update the nodes for reclass inventory
