+# How to contribute to SYSTEM
+
+## Guidelines
+
+- Read and understand the documentation in `doc/dev/`, starting with `DEV_MANUAL.md`.
+- Make commits, branches, patches, patchsets, and emails limited to "one logical thing".
+- Follow the example of what you see in the rest of the codebase.
+- Reach out for help if you need assistance.
+
+
+## How to submit patches
+
+Email patchsets, bug reports, etc. directly to Tristan Williams <tgwil@tgwil.net> using one of the following subject templates:
+
+- Patchsets: `SYSTEM: Patchset: [description of changes]`
+- Bug Reports: `SYSTEM: Bug Report: [description of bug]`
+- Development Discussion: `SYSTEM: RFC: [description of discussion topic]`
+- Questions/Help: `SYSTEM: Help: [description of question]`
+
+Be informative in emails, but don't overwhelm with useless details.
