+# Presentation and Analytics Layer
+
+Presentation and Analytics Layer (PAL) makes possible to present and
+analyse the test results generated by CSIT Jenkins jobs.
+
+## Using PAL in the Local mode
+
+The local mode makes possible to use:
+1. a single XML file,
+2. a directory with XML files, or
+3. a directory with directories of XML files.
+
+### Using a single XML file
+
+Run the script with the path to a local XML file, e.g.:
+
+ ./run_local_report.sh --file output.xml
+
+### Using a directory of XML files
+
+Store all XML files in a directory, e.g.:
+
+ csit-vpp-perf-verify-2001-3n-dnv/
+ ├── csit-vpp-perf-verify-2001-3n-dnv__5__output_info.xml
+ ├── csit-vpp-perf-verify-2001-3n-dnv__6__output_info.xml
+ └── csit-vpp-perf-verify-2001-3n-dnv__7__output_info.xml
+
+and use:
+
+ ./run_local_report.sh --directory csit-vpp-perf-verify-2001-3n-dnv/
+
+### Using a directory with directories of XML files.
+
+Store all XML files in a directory structure, e.g.:
+
+ local/
+ ├── csit-vpp-perf-verify-2001-2n-clx
+ │ ├── csit-vpp-perf-verify-2001-2n-clx__28__output_info.xml
+ │ └── csit-vpp-perf-verify-2001-2n-clx__29__output_info.xml
+ └── csit-vpp-perf-verify-2001-3n-dnv
+ ├── csit-vpp-perf-verify-2001-3n-dnv__5__output_info.xml
+ ├── csit-vpp-perf-verify-2001-3n-dnv__6__output_info.xml
+ └── csit-vpp-perf-verify-2001-3n-dnv__7__output_info.xml
+
+and use:
+
+ ./run_local_report.sh --directory local/
