# 6 Before You Commit

- Make sure you have a ChangeLog entry
- Make sure any new method/class is documented in the header file. or `Appkit/Appkit.h` if appropriate.
- If you have added a class, add the class to `Foundation/Foundation.h`
- If you have updated and configure checks, be sure to run both autoconf and autoheader.
- Make sure everything still compiles at least on the most common platform (ie Intel processor, GNU/Linux operating system, with the GCC compiler and ObjC runtime), and ideally on ms-windows too.
- Make sure you've tested the change and contributed testcase code to the testsuite. Run the testsuite on the systems where you compiled.
- Make sure that documentation generation still works by running 'make’ in the Documentation directory.
