The Paho project has been created to provide scalable open-source implementations of open and standard messaging protocols aimed at new, existing, and emerging applications for Machine-to-Machine (M2M) and Internet of Things (IoT).
Paho reflects the inherent physical and cost constraints of device connectivity. Its objectives include effective levels of decoupling between devices and applications, designed to keep markets open and encourage the rapid growth of scalable Web and Enterprise middleware and applications. Paho is being kicked off with MQTT publish/subscribe client implementations for use on embedded platforms, along with corresponding server support as determined by the community.

3. Make sure that you _sign-off_ your Git commits in the following format:
``` Signed-off-by: John Smith <johnsmith@nowhere.com> ``` This is usually at the bottom of the commit message. You can automate this by adding the '-s' flag when you make the commits. e.g. ```git commit -s -m "Adding a cool feature"```
4. Ensure that the email address that you make your commits with is the same one you used to sign up to the Eclipse Foundation website with.
A [web browsable repository](http://git.eclipse.org/c/paho/org.eclipse.paho.mqtt.c.git) is available.
1.[Fork the repository on GitHub](https://github.com/eclipse/paho.mqtt.c/fork)
2. Clone the forked repository onto your computer: ``` git clone https://github.com/<your username>/paho.mqtt.c.git ```
3. Create a new branch from the latest ```develop``` branch with ```git checkout -b YOUR_BRANCH_NAME origin/develop```
4. Make your changes
5. If developing a new feature, make sure to include JUnit tests.
6. Ensure that all new and existing tests pass.
7. Commit the changes into the branch: ``` git commit -s ``` Make sure that your commit message is meaningful and describes your changes correctly.
8. If you have a lot of commits for the change, squash them into a single / few commits.
9. Push the changes in your branch to your forked repository.
10. Finally, go to [https://github.com/eclipse/paho.mqtt.c](https://github.com/eclipse/paho.mqtt.c) and create a pull request from your "YOUR_BRANCH_NAME" branch to the ```develop``` one to request review and merge of the commits in your pushed branch.
