+## Contributing Guidelines
+
+Ensure that you adhere to the following guidelines:
+
+- Should be about principles and concepts that can be applied in any company or individual project. Do not focus on particular tools or tech stack(which usually change over time).
+- Adhere to the Code of Conduct.
+- Should be relevant to the roles and responsibilities of an SRE.
+- Should be locally tested (see steps for testing) and well formatted.
