 4. The project team will label the issue and evaluate the pull request in the weekly configuration control board (CCB) meeting. For more information, visit [The cFS CCB Process.](https://github.com/nasa/cFS/wiki/The-cFS-CCB-Process)
 5. If the pull request is accepted, it will be merged into cFS.
 
+## Writing High-Quality Code
+
+1. Follow cFS code conventions (formatting, symbol naming, file naming, etc). Do *not* change/reformat existing code, except to address your changes.
+    - The cFS submodules uses the Format Check workflow to ensure users follow the [clang-format-10](https://releases.llvm.org/10.0.0/tools/clang/docs/ClangFormat.html) style. 
+    - The [cFS_IdentifierNamingConvention document](https://github.com/nasa/cFE/blob/main/docs/cFS_IdentifierNamingConvention.md) provides a simple naming convention guide for cFE/cFS for commands and telemetry that simplifies the EDS to ground telemetry and commands database conversion.
+    - The [cFE Application Developers Guide](https://github.com/nasa/cFE/blob/main/docs/cFE%20Application%20Developers%20Guide.md) contains code conventions such as naming conventions for header files. 
+
+2. For any new API's, add unit tests to cover nominal and off-nominal conditions.
+
+3. Add/edit stubs to the unit test codebase for any new/modified functions.
+
+4. For any changes to existing API's, alter the unit tests to cover the changes (and remove tests made irrelevant due to your changes).
+
+5. Review the static code analyses results. 
+    - Push code changes to the appropriate forked repository. 
+    - Go to the Actions tab and enable GitHub Actions Workflow. The CodeQL Analyis and Static Analysis will be triggered for all pushed code. 
+    - Review these workflows for any warnings or errors. 
+    - Once successful, create a pull request. 
+
+For more information on our GitHub Action Workflows, view our [Security Policy](https://github.com/nasa/cFS/security/policy).
