+# QTIP Developer Guide
+
+This guide is about how to **develop** QTIP.
+
+If you just want to use it for performance benchmark, check the user guide
+instead.
+
+## Getting Started
+
+### Source code
+
+```bash
+~$ git clone https://gerrit.opnfv.org/gerrit/qtip
+```
+
+### VirtualEnv
+
+It is recommended to use [virtualenv](https://virtualenv.pypa.io) to isolate
+your development environment from system, especially when you are working on
+several different projects.
+
+### Testing
+
+QTIP use [tox](https://tox.readthedocs.io) to automate the testing tasks
+
+```bash
+$ pip install tox
+$ tox
+```
+
+## Architecture
+
+**TODO**: move to design spec
+
+QTIP has a flexible architecture to allow different deployment mode
+
+- **Standalone**: full feature performance benchmark platform.
+- **Agent**: minimal agent driven by external test runners.
+
+### Standalone Mode (Solo)
+
+QTIP instance deployed in container, VM or host generate benchmark report and
+push data to Indices Hub for storage and visualization.
+
+![solo](https://wiki.opnfv.org/download/attachments/8687017/Standalone.png?api=v2)
+
+### Agent Mode (Melody)
+
+QTIP Collector and Reporter driven by external test framework or runner such as
+[yardstick](https://wiki.opnfv.org/display/yardstick),
+[pytest](http://doc.pytest.org/) and etc.

+**************************
+Integration with Yardstick
+**************************
+
+Problem description
+===================
+
+For each specified QPI [1]_, QTIP needs to select a suite of test cases and collect
+required test results. Based on these results, Qtip calculates the score.
+
+Proposed change
+===============
+Qtip has a flexible architecture [2]_ to support different mode: standalone and agent.
+It is recommended to use **agent mode** to work with existing test runners. Yardstick will
+act as a runner to generate test result and trigger Qtip agent on the completion of test.
+
+
+Work Items in Yardstick
+-----------------------
+
+1. Create a customized suite in Yardstick
+
+Yardstick not only has many existing suites but also support customized suites. Qtip could
+create a suite named **Qtip-PoC** in Yardstick repo to verify workflow of Qtip agent mode.
+
+2. Launch Qtip in Yardstick
+
+Whether to launch Qtip will be determined by checking the existence of OS environment
+variable *QTIP*. If it exists, Qtip will be launched by using Yardstick CLI
+`yardstick plugin install` [3]_.
+
+3. Yardstick interacts with Qtip
+
+See
+`Yardstick-Qtip+integration <https://wiki.opnfv.org/display/yardstick/Yardstick-Qtip+integration>`_
+for details.
+
+Work Items in Qtip
+------------------
+
+1. Provide an API for Yardstick to post test result and environment info
+
+After completing test execution, Yardstick will post test result and enviroment info with
+JSON format via QTIP API. See
+`Yardstick-Qtip+integration <https://wiki.opnfv.org/display/yardstick/Yardstick-Qtip+integration>`_
+for details.
+
+2. Parse yardstick test result
+
+When Qtip agent receive Yarstick test result and enviroment info, Qtip agent will extract
+metrics which is definded in metric spec configuration file. Based on these metrics, Qtip
+agent will caculate QPI.
+
+3. Provide an API for querying QPI
+
+Qtip will provide an API for querying QPI. See
+`Yardstick-Qtip+integration <https://wiki.opnfv.org/display/yardstick/Yardstick-Qtip+integration>`_
+for details.
