+## New libraries and corrections
+
+Submissions of new libraries: I accept submissions (as issues or as pull requests). Please
+note that every file that must be included in a user's project counts; a header and a source
+file is 2 files, but a header file, source file, and LICENSE (if the license isn't in the
+source file) is 3 files, and won't be accepted, because it's not 2 files. But actually
+'LICENSE' is a problem for just dropping the library in a source tree anyway, since it's
+not scoped to just the library, so library authors are encouraged to include the license in the
+source file and not require a separate LICENSE.
+
+Corrections: if information for a library above is wrong, please send a correction as an
+issue, pull request, or email. Note that if the list indicates a library works from both
+C/C++, but it doesn't, this could be an error in the list or it could be a bug in the
+library. If you find a library doesn't work in 32-bit or 64-bit, the library should be
+removed from this list, unless it's a bug in the library.
+
+## *List FAQ*
+
+### Can I link directly to this list?
+
+Yes. [This is the preferred link.](https://github.com/nothings/single_file_lib)
+
+### Why isn't library XXX which is made of 3 or more files on this list?
+
+I draw the line arbitrarily at 2 files at most. (Note that some libraries that appear to
+be two files require a separate LICENSE file, which made me leave them out). Some of these
+libraries are still easy to drop into your project and build, so you might still be ok with them.
+But since people come to stb for single-file public domain libraries, I feel that starts
+to get too far from what we do here.
+
+### Why isn't library XXX which is at most two files and has minimal other dependencies on this list?
+
+Probably because I don't know about it, feel free to submit a pull request, issue, email, or tweet it at
+me (it can be your own library or somebody else's). But I might not include it for various
+other reasons, including subtleties of what is 'minimal other dependencies' and subtleties
+about what is 'lightweight'.
+
+### Why isn't SQLite's amalgamated build on this list?
+
+Come on.
