 Overview
 ========
 
-This is the **F**\ast **D**\ata **I**/**O** Project (FD.io) **C**\ontinuous
-**S**\ystem **I**\ntegration and **T**\esting (CSIT) project report for CSIT
-|release| system testing of VPP-17.01 release. Initial sections of the report
-describe FD.io functional and performance tests and their continuous execution
-achieved in CSIT |release|. This is followed by high-level overview of FD.io
-test environments running in Linux Foundation (LF) FD.io Continuous
-Performance Labs), CSIT |release| release notes and result highlights.
-Subsequent sections list the functional and performance detailed test results
-generated by LF FD.io Jenkins system executing CSIT jobs running tests
-against the VPP-17.01 release and associated sub-systems (HoneyComb, DPDK).

-The exact structure of the report is as follows:
-
-#. ``Introduction`` - Includes: ``Overview`` - this section;
-   ``CSIT Test Naming`` - describing CSIT naming convention for test suites and
-   test cases, important to understand to correctly interpret the reported
-   results; ``General Remarks`` - additional notes related to this report.
-#. ``VPP Performance Tests HW`` - Summary of VPP performance tests executed in
-   physical Hardware testbed. Includes: ``Overview`` - containing topology
-   description and list of executed tests; ``Performance Tests Naming`` - lists
-   CSIT naming specifics for performance tests; ``CSIT Release Notes`` - with
-   changes in CSIT |release| including major test additions, performance
-   improvements, changes in testing environment and methodology and known
-   issues; ``Performance Measurements Methodology`` - details testing
-   methodology followed for multi-thread multi-core, packet throughput and
-   latency, and KVM VM vhost tests; ``Report Addendum Targets`` - lists content
-   to be added to this report as part of CSIT |release|.

-FD.io CSIT system is developed using two main coding platforms: Robot
-Framework (RF) and Python. CSIT |release| source code for the executed test
-suites is available in CSIT branch |release| in the directory
-"./tests/<name_of_the_test_suite>". A local copy of CSIT source code can be
-obtained by cloning CSIT git repository - "git clone
-https://gerrit.fd.io/r/csit". The CSIT testing virtual environment can be run
-on a local computer workstation (laptop, server) using Vagrant by following
-the instructions in `CSIT tutorials
-<https://wiki.fd.io/view/CSIT#Tutorials>`_.
+This is the **F**\ast **D**\ata **I**/**O** Project (**FD.io**) **C**\ontinuous
+**S**\ystem **I**\ntegration and **T**\esting (**CSIT**) project report for CSIT
+|release| system testing of VPP-17.01 release.
+
+The report describes CSIT functional and performance tests and their
+continuous execution delivered in CSIT |release|. A high-level overview is
+provided for each CSIT test environment running in Linux Foundation (LF) FD.io
+Continuous Performance Labs. This is followed by summary of all executed tests
+against the VPP-17.01 release and associated sub-systems (HoneyComb, DPDK),
+CSIT |release| release notes, result highlights and known issues. More
+detailed description of each environment, pointers to CSIT test code
+documentation and detailed test resuls with links to the source data files are
+also provided.
