+SeaBIOS welcomes contributions of code (either fixing bugs or adding
+new functionality). At a high level, the process to contribute a
+change is:
+
+1. [Obtain](Download.md) the current code and documentation
+2. Enhance and test the code locally
+3. Submit changes to the SeaBIOS [mailing list](Mailinglist.md) as a
+   patch
+4. Receive feedback, answer questions, and possibly provide updated
+   patches
+5. When accepted, a maintainer (Kevin O'Connor or Gerd Hoffman) will
+   commit the change to the master SeaBIOS repository
+
+The SeaBIOS patch submission process is similar to the
+[QEMU process](http://wiki.qemu.org/Contribute/SubmitAPatch). Please
+review the QEMU process for more details and tips on the best way to
+submit patches. The SeaBIOS C code does follow a slightly different
+coding style from QEMU (eg, mixed code and C99 style variable
+declarations are encouraged, braces are not required around single
+statement blocks), however patches in the QEMU style are acceptable.
+
+As with QEMU, commits must contain a "Signed-off-by" line using your
+real name (sorry, no pseudonyms or anonymous contributions) and a
+current email address. It indicates agreement with the terms of the
+[developer certificate of origin](developer-certificate-of-origin).
