 An environment suitable for running docker containers is recommended.
 
-As a docker container
----------------------
+Using Cloudify deployment
+-------------------------
 
-**datafile** is delivered as a docker container based on openjdk:8-jre-alpine.  The
+The first possibility is to use blueprints and cfy commands.
+
+Deployment Prerequisite/dependencies
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Make sure that **cfy** is installed and configured to work with the Cloudify deployment.
+
+Make sure the Message Router and Data Router are running.
+
+Deployment steps
+^^^^^^^^^^^^^^^^
+
+1. Execute bash on the cloudify manager kubernetes pod. 
+
+.. code-block:: json
+    kubectl -n onap exec -it <dev-dcaegen2-dcae-cloudify-manager> bash
+
+2. Download the dfc `blueprint`_.
+.. _blueprint 
+
+    https://gerrit.onap.org/r/gitweb?p=dcaegen2/platform/blueprints.git;a=blob;f=blueprints/reference_templates/k8s-datafile-collector.yaml-template;h=17d2aedec131154b4f5f84a08a099b0364b1e627;hb=HEAD
+
+3. Run Cloudify Install command to install dfc.
+
+.. code-block:: json
+    cfy install <dfc-blueprint-path>
+
+Sample output:
+
+..code-block:: json
+    cfy install k8s-datafile.yaml
+
+Run '*cfy events list -e 37da3f5f-a06b-4ce8-84d3-8b64ccd81c33'* to retrieve the execution's events/logs.
+
+Validation
+^^^^^^^^^^
+
+curl <dcaegen2-dcae-healthcheck> and check if datafile-collector is in *'ready'* state.
+
+Standalone deployment of a container
+------------------------------------
+
+DFC is delivered as a docker container based on openjdk:8-jre-alpine.  The
 host or VM that will run this container must have the docker application
 loaded and available to the userID that will be running the DFC container.
 
-Also required is a working DMAAP/MR and DMAAP/DR environment.  datafile
+Also required is a working DMAAP/MR and DMAAP/DR environment. DFC
 subscribes to DMAAP/MR fileReady event as JSON messages and publishes the downloaded files to the DMAAP/DR.
 
 Installation
 ^^^^^^^^^^^^
 
-The following command will download the latest datafile container from
+The following command will download the Dublin version of the datafile container from
 nexus and launch it in the container named "datafile":
 
     ``docker run -d -p 8100:8100 -p 8433:8433
-    nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.datafile.datafile-app-server:latest``
+    nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.datafile.datafile-app-server:1.1.2``
+
+For another version, it is possible to replace the tag '1.1.2' with any version that seems suitable (including latest).
+Available images are visible following this `link`_.
+
+.. _link https://nexus3.onap.org/#browse/search=keyword%3D*datafile*
+
+Another option is to pull the container first, and then run it with the image ID:
+
+    ``docker pull nexus3.onap.org:10001/onap/org.onap.dcaegen2.collectors.datafile.datafile-app-server:latest``
+
+    ``docker images | grep 'datafile'``
+
+    ``docker run -d -p 8100:8100 -p 8433:8433 <image ID>``
+
+The grep command will display the images corresponding to DFC. There can be several due to remotely or locally built
+image, and also to different tags, i.e. different versions.
