+
+
+## Preparing the environment
+
+1. Clone the repository `log_helper`:
+* Clone with SSH
+    ~~~~
+    git clone ssh://gerrit.mcp.mirantis.com:29418/mcp/osccore-qa-testing-tools
+    ~~~~
+  
+2. Navigate to the `log_helper/` folder:
+   ~~~
+   cd log_helper/
+   ~~~
+
+3. Edit 'config.py' file and provide it with required values:
+
+   * `RESULTS_DIR`, `LOG_DIR` and `TEMPEST_REPORT_YAML`
+
+
+4. In the `log_helper/` folder install log_helper tool:
+    ~~~~
+    python3 -m pip install -e .
+    ~~~~
