+FAQ
+---
+
+#### What's the license?
+
+These libraries are in the public domain. You can do anything you
+want with them. You have no legal obligation
+to do anything else, although I appreciate attribution.
+
+They are also licensed under the MIT open source license, if you have lawyers
+who are unhappy with public domain. Every source file includes an explicit
+dual-license for you to choose from.
+
+#### <a name="other_libs"></a> Are there other single-file public-domain/open source libraries with minimal dependencies out there?
+
+[Yes.](https://github.com/nothings/single_file_libs)
+
+#### If I wrap an stb library in a new library, does the new library have to be public domain/MIT?
+
+No, because it's public domain you can freely relicense it to whatever license your new
+library wants to be.
+
+#### What's the deal with SSE support in GCC-based compilers?
+
+stb_image will either use SSE2 (if you compile with -msse2) or
+will not use any SIMD at all, rather than trying to detect the
+processor at runtime and handle it correctly. As I understand it,
+the approved path in GCC for runtime-detection require
+you to use multiple source files, one for each CPU configuration.
+Because stb_image is a header-file library that compiles in only
+one source file, there's no approved way to build both an
+SSE-enabled and a non-SSE-enabled variation.
+
+While we've tried to work around it, we've had multiple issues over
+the years due to specific versions of gcc breaking what we're doing,
+so we've given up on it. See https://github.com/nothings/stb/issues/280
+and https://github.com/nothings/stb/issues/410 for examples.
+
+#### Some of these libraries seem redundant to existing open source libraries. Are they better somehow?
+
+Generally they're only better in that they're easier to integrate,
+easier to use, and easier to release (single file; good API; no
+attribution requirement). They may be less featureful, slower,
+and/or use more memory. If you're already using an equivalent
+library, there's probably no good reason to switch.
+
+#### Can I link directly to the table of stb libraries?
+
+You can use [this URL](https://github.com/nothings/stb#stb_libs) to link directly to that list.
+
+#### Why do you list "lines of code"? It's a terrible metric.
+
+Just to give you some idea of the internal complexity of the library,
+to help you manage your expectations, or to let you know what you're
+getting into. While not all the libraries are written in the same
+style, they're certainly similar styles, and so comparisons between
+the libraries are probably still meaningful.
+
+Note though that the lines do include both the implementation, the
+part that corresponds to a header file, and the documentation.
+
+#### Why single-file headers?
+
+Windows doesn't have standard directories where libraries
+live. That makes deploying libraries in Windows a lot more
+painful than open source developers on Unix-derivates generally
+realize. (It also makes library dependencies a lot worse in Windows.)
+
+There's also a common problem in Windows where a library was built
+against a different version of the runtime library, which causes
+link conflicts and confusion. Shipping the libs as headers means
+you normally just compile them straight into your project without
+making libraries, thus sidestepping that problem.
+
+Making them a single file makes it very easy to just
+drop them into a project that needs them. (Of course you can
+still put them in a proper shared library tree if you want.)
+
+Why not two files, one a header and one an implementation?
+The difference between 10 files and 9 files is not a big deal,
+but the difference between 2 files and 1 file is a big deal.
+You don't need to zip or tar the files up, you don't have to
+remember to attach *two* files, etc.
+
+#### Why "stb"? Is this something to do with Set-Top Boxes?
+
+No, they are just the initials for my name, Sean T. Barrett.
+This was not chosen out of egomania, but as a moderately sane
+way of namespacing the filenames and source function names.
+
+#### Will you add more image types to stb_image.h?
+
+No. As stb_image use has grown, it has become more important
+for us to focus on security of the codebase. Adding new image
+formats increases the amount of code we need to secure, so it
+is no longer worth adding new formats.
+
+#### Do you have any advice on how to create my own single-file library?
+
+Yes. https://github.com/nothings/stb/blob/master/docs/stb_howto.txt
+
+#### Why public domain?
+
+I prefer it over GPL, LGPL, BSD, zlib, etc. for many reasons.
+Some of them are listed here:
+https://github.com/nothings/stb/blob/master/docs/why_public_domain.md
+
+#### Why C?
+
+Primarily, because I use C, not C++. But it does also make it easier
+for other people to use them from other languages.
+
+#### Why not C99? stdint.h, declare-anywhere, etc.
+
+I still use MSVC 6 (1998) as my IDE because it has better human factors
+for me than later versions of MSVC.
