+CLI helper tool
+======================
+
+This CLI helper tool gathers all log lines related to resource | req-id from particular folder with logs.
+All related resources and their IDs used in Tempest tests are stored in machine-readable YAML file with the following format:
+
+<test identifier>:
+  status: PASSED|FAILED
+  resources:
+    <openstack-service name (nova|neutron|glance|keystone)>:
+       <resource-name (port|server|security-group|router)>:
+       <request-id (req-xxxx) >:
+         name: <resource name (test-port-mytest|test-vm-)>
+         id/uuid: <resource id>
+         request: <exact request>
+        http:
+           error: <if exists>
+           status_code: <>
+
+How to use
+----------
+
+- Extract/save all openstack pod logs to folder (ex. pod-logs)
+
+- Generate tempest report using report_parcer tool
+
+- Run log_helper tool with folder name and tempest report YAML file as input parameters:
+
+``python3 log_helper.py <folder-with-logs> <tempest-report-yaml>``
