+Introduction
+############
+
+`QTIP`_ is the project for **Platform Performance Benchmarking** in `OPNFV`_. It aims to provide user a simple indicator
+for performance, simple but supported by comprehensive testing data and transparent calculation formula.
+
+QTIP introduces a concept called **QPI**, a.k.a. QTIP Performance Index, which aims to be a **TRUE** indicator of
+performance. **TRUE** reflects the core value of QPI in four aspects
+
+- *Transparent*: being an open source project, user can inspect all details behind QPI, e.g. formulas, metrics, raw data
+- *Reliable*: the integrity of QPI will be guaranteed by traceability in each step back to raw test result
+- *Understandable*: QPI is broke down into section scores, and workload scores in report to help user to understand
+- *Extensible*: users may create their own QPI by composing the existed metrics in QTIP or extend new metrics
+

+Benchmarks
+##########
+
+The builtin benchmarks of QTIP are located in ``<package_root>/benchmarks`` folder
+
+- *QPI*: specifications about how an QPI is calculated and sources of metrics
+- *metric*: performance metrics referred in QPI, currently it is categorized by performance testing tools
+- *plan*: executable benchmarking plan which collects metrics and calculate QPI
