-# Procfs-sensor
+VirtualWatts is a software-defined power meter based on the PowerAPI toolkit.
+VirtualWatts a configurable software that can estimate the power consumption of
+process inside a VM in real-time.
+VirtuallWatts is supposed to be used inside a VM. It need to receive two metrics :
 
-Proc file system Sensor is a tool that monitor the CPU usage of process using the proc
-file system.
-
-The sensor use the proc file system of the Linux kernel. It is only available on Linux.
-
-The sensor could be used in a virtual machine.
+- The energy consumption of the VM, usually made with
+  [SmartWatts](https://github.com/powerapi-ng/smartwatts-formula)
+- The cpu usage of the tracked processes and the global cpu usage, as provided
+  by [procfs-sensor](https://github.com/powerapi-ng/procfs-sensor).
 
 # About

+# Contributing to Procfs-Sensor
+
+Thank you for your interest in contributing to Procfs-Sensor! There are multiple ways to contribute, and we appreciate all contributions.
+
+# Ways to contribute
+
+Pull requests should be made on the pre-release branch. This way they will be
+included in the next stable release (available on master).
+Each pull request should pass the tests and be correctly linted (`pylint` and
+`flake8`) to pass the CI.
+
+Each pull request have to be reviewed before beeing accepted. Some modifications can be
+asked by the projet's managers.
+
+Here is different ways to contribute to Procfs-Sensor.
+
+## Bug report
+
+If you are working with Procfs-Sensor and you encounter a bug, please let us know.
+You are welcome to submit an issue which describe the bug and it context with a
+small test or a code snippet that reproduce the issue.
+
+## Bug Fixes
+
+If you are interested to contribute to Procfs-Sensor you can fixes reported bugs.
+They are listed in the issues with the label _bug_
+
+Your pull request should contain a test that reproduce the bug, if the test do
+not already exist, and the bug fix.
+Please submit one pull request for each bug fix.
+
+## Patches
+
+You can submit bigger contributions in the form of patches.
+A patch should :
+
+- include unit tests
+- be an isolated changes. If you have uncorelated changes you should submit multiple pull requests to make it easier for us to review
