+VPP MRR Performance Dashboard
+=============================
+
+Description
+-----------
+
+Dashboard tables list a summary of per test-case VPP MRR performance trend
+values and detected anomalies (Maximum Receive Rate - received packet rate
+under line rate load). Data comes from trending MRR jobs executed every 12 hrs
+(2:00, 14:00 UTC). Trend and anomaly calculations are done over a rolling
+window of <N> samples, currently with N=14 covering last 7 days. Separate
+tables are generated for tested VPP worker-thread-core combinations (1t1c,
+2t2c, 4t4c).
+
+Legend to table:
+
+    - "Test case": name of CSIT test case, naming convention here
+      `CSIT/csit-test-naming <https://wiki.fd.io/view/CSIT/csit-test-naming>`_
+    - "Thput trend [Mpps]": last value of trend over rolling window.
+    - "Anomaly value [Mpps]": in precedence - i) highest outlier if 3
+      consecutive outliers, ii) highest regression if regressions detected,
+      iii) highest progression if progressions detected, iv) nil if normal i.e.
+      within trend.
+    - "Anomaly vs. Trend [%]": anomaly value vs. trend value.
+    - "Classification": outlier, regression, progression, normal - observed
+      over a rolling window.
+    - "# Outliers": number of outliers detected.
+
+Tables are listed in sections 1.x. Followed by daily trending graphs in
+sections 2.x. Daily trending data used to generate the graphs is listed in
+sections 3.x.
