+Welcome to TESTAPI Update!
+========================
+
+
+This file is used to describe how testapi update works
+
+----------
+How to use
+---------------
+
+#### <i class="icon-file"></i> backup mongodb
+
+arguments:
+: -u/--url: Mongo DB URL, default = mongodb://127.0.0.1:27017/
+the backup output will be put under dir/db__XXXX_XX_XX_XXXXXX/db
+-d/--db: database for the backup, default = test_results_collection
+
+usage:
+```
+python backup_mongodb.py
+```
+
+#### <i class="icon-file"></i> restore mongodb
+
+arguments:
+: -u/--url: Mongo DB URL, default = mongodb://127.0.0.1:27017/
+  -i/--input_dir: Input directory for the Restore, must be specified,
+  the restore input must be specified to dir/db__XXXX_XX_XX_XXXXXX/db
+  -d/--db: database name after the restore, default = basename of input_dir
+
+usage:
+```
+python restore_mongodb.py
+```
+#### <i class="icon-file"></i> update mongodb
+
+ arguments:
+: -u/--url: Mongo DB URL, default = mongodb://127.0.0.1:27017/
+ -d/--db: database name to be updated, default = test_results_collection
+
+changes need to be done:
+change collection name, modify changes.collections_old2New
+ > collections_old2New = {
+     'old_collection': 'new_collection',
+ }
+
+ change field name, modify changes.fields_old2New
+ > fields_old2New = {
+     'collection': [(query, {'old_field': 'new_field'})]
+ }
+
+ change the doc, modify changes.docs_old2New
+ > docs_old2New = {
+     'test_results': [
+         ({'field': 'old_value'}, {'field': 'new_value'}),
+         (query, {'field': 'new_value'}),
+     ]
+ }
+
+#### <i class="icon-file"></i> update opnfv-testapi process
+This script must be run right in this directory and remember to
+change ../etc/config.ini before running this script.
+
+operations includes:
+: kill running test_collection_api & opnfv-testapi
+install or update dependencies according to ../requirements.txt
+install opnfv-testapi
+run opnfv-testapi
+
+usage:
+```
+python update_api.py
+```
+#### <i class="icon-file"></i> update opnfv/testapi container
+Here ansible-playbook is used to implement auto update.
+Please make sure that the remote server is accessible via ssh.
+
+install ansible, please refer:
+```
+http://docs.ansible.com/ansible/intro_installation.html
+```
+
+playbook-update.sh
+
+arguments:
+: -h|--help           show this help text
+-r|--remote         remote server
+-u|--user           ssh username used to access to remote server
+-i|--identity       ssh PublicKey file used to access to remote server
+-e|--execute        execute update, if not set just check the ansible connectivity
+
+usage:
+```
+ssh-agent ./playbook-update.sh -r testresults.opnfv.org -u serena -i ~/.ssh/id_rsa -e
+```
+
+> **Note:**
+
+> - If documents need to be changed, please modify file
+templates/changes_in_mongodb.py, and refer section **update mongodb**
