+How to use functionality
+========================
+
+Basic information
+-----------------
+Certification Client needs the following configuration parameters to work properly:
+
+1. Parameters for connection to certification service API and generate trustore and keystore
+  
+  - REQUEST_URL *(default: https://aaf-cert-service:8443/v1/certificate/)*
+  - REQUEST_TIMEOUT *(default: 30000)*
+  - OUTPUT_PATH *(required)*
+  - CA_NAME *(required)* 
+
+
+2. Parameters for generate CSR file:
+  
+  - COMMON_NAME *(required)*
+  - ORGANIZATION *(required)*
+  - ORGANIZATION_UNIT *(optional)*
+  - LOCATION *(optional)*
+  - STATE *(required)*
+  - COUNTRY *(required)*
+  - SANS *(optional)(SANS's should be separated by a colon)*
+
+3. Parameters for secure connection: 
+
+  - KEYSTORE_PATH *(required)*
+  - KEYSTORE_PASSWORD *(required)*
+  - TRUSTSTORE_PATH *(required)*
+  - TRUSTSTORE_PASSWORD *(required)*
+
+Certification Service Client image can be find on Nexus repository :
+
+.. code-block:: bash
+
+  nexus3.onap.org:10001/onap/org.onap.aaf.certservice.aaf-certservice-client:latest 
+
+
+As standalone docker container
+------------------------------
+You need certification files to connect to certification service API via https. Information how to generate truststore and keystore files you can find in project repository README `Gerrit GitWeb <https://gerrit.onap.org/r/gitweb?p=aaf%2Fcertservice.git;a=summary>`__
+
+To run Certification Client as standalone docker container execute following steps: 
+
+1. Create file with environments as in example below:
+
+.. code-block:: bash
+
+  #Client envs
+  REQUEST_URL=<url to certification service API>
+  REQUEST_TIMEOUT=10000
+  OUTPUT_PATH=/var/certs
+  CA_NAME=RA
+  #Csr config envs
+  COMMON_NAME=onap.org
+  ORGANIZATION=Linux-Foundation
+  ORGANIZATION_UNIT=ONAP
+  LOCATION=San-Francisco
+  STATE=California
+  COUNTRY=US
+  SANS=test.onap.org:onap.com
+  #Tls config envs
+  KEYSTORE_PATH=/etc/onap/aaf/certservice/certs/certServiceClient-keystore.jks
+  KEYSTORE_PASSWORD=<password to keystore.jks>
+  TRUSTSTORE_PATH=/etc/onap/aaf/certservice/certs/certServiceClient-truststore.jks
+  TRUSTSTORE_PASSWORD=<password to certServiceClient-truststore.jks>
+
+2. Run docker container as in following example (API and client must be running in same network):
+
+.. code-block:: bash
+
+ docker run \
+    --rm \
+    --name aafcert-client \
+    --env-file <path to environments file> \
+    --network <docker network of cert service> \
+    --mount type=bind,src=<path to local directory>,dst=<OUTPUT_PATH> \
+    --volume <local path to keystore.jks>:<KEYSTORE_PATH> \
+    --volume <local path to trustore.jks>:<TRUSTSTORE_PATH> \
+    nexus3.onap.org:10001/onap/org.onap.aaf.certservice.aaf-certservice-client:latest 
+
+
+
+After successful creation of certifications, container exits with exit code 0, expected logs looks like:
+
+.. code-block:: bash
+
