+## Things to Avoid
+
+1. Please do not add external dependencies or libraries without discussing them first.
+2. The goal of this program is keep the program as lightweight as possible. Try to avoid things that might add uneeded bloat.
+3. Do not manually increase the version number, or touch the build scripts unless it is related to the issue.
+4. Do not make machine specific changes to solutions or projects. The project should be able to build on any machine with the files provided.
+5. Do not use a build system other than MSBUILD.
+6. Code Style is not strict, but try to follow what is already in the project.
+
+## Pull Request Process
+
+1. Coordinate work being done via issues or PR before work is done.
+2. All work must be done on the develop branch or a branch checked out from develop.
+3. Update the [CHANGELOG](CHANGELOG.md) with details of changes made. 
+4. If tests can be added, consider adding them.
+5. All builds must actually build, pass pre-scripts, and all tests before being merged.
