+
+> Note :
+>
+> When using the GitHub issue tracker, please don't upload your privacy data(e.g. Serial Number, MNID and so on) in there. Please just include the examples below.
+
+Examples of useful information :
+
+- A reproducible test steps
+- The STDK version being used
+- The Device(Board Name) & BSP information being used (e.g. WEMOS D1 Mini & esp8266)
+- If there is, any modifications you've made
+- If there is, anything unusual about your environment
+
+### Pull Requests
+
+We would love to accept your patches. Please contribute patches via Pull Requests.
+
+According to the our SCM(Software Configuration Management) policy, the `master` branch will be managed for official releases. Therefore we will just merge your patches into the `develop` branch after minimally testing to ensure nothing major is broken. And these patches which were merged into the `develop` branch through several Pull Requests will eventually be integrated into the `master` branch after passing the test on all supported platforms.
+
+1. Fork the repository.
+2. Develop based on the [develop](https://github.com/SmartThingsCommunity/st-device-sdk-c/tree/develop) branch.
+3. Ensure that your code adheres to the existing style in the sample to which you are contributing.
+4. Ensure local tests pass about your code changes.
+5. In order to ensure that the Pull Request is integrated without a merge conflict, please create a Pull Request based on the latest `develop` branch.
+6. Finally, create a pull request against the `develop` branch.
+
+### Security issue notifications
+
+If you discover a potential security issue in this project we ask that you notify us via our [e-mail](mailto:[email protected]). Please do NOT create a public GitHub issue.
