+#### How do I use these libraries?
+
+The idea behind single-header file libraries is that they're easy to distribute and deploy
+because all the code is contained in a single file. By default, the .h files in here act as
+their own header files, i.e. they declare the functions contained in the file but don't
+actually result in any code getting compiled.
+
+So in addition, you should select _exactly one_ C/C++ source file that actually instantiates
+the code, preferably a file you're not editing frequently. This file should define a
+specific macro (this is documented per-library) to actually enable the function definitions.
+For example, to use stb_image, you should have exactly one C/C++ file that doesn't
+include stb_image.h regularly, but instead does
+
+    #define STB_IMAGE_IMPLEMENTATION
+    #include "stb_image.h"
+
+The right macro to define is pointed out right at the top of each of these libraries.

 #### Will you add more image types to stb_image.h?
 
-If people submit them, I generally add them, but the goal of stb_image
-is less for applications like image viewer apps (which need to support
-every type of image under the sun) and more for things like games which
-can choose what images to use, so I may decline to add them if they're
-too rare or if the size of implementation vs. apparent benefit is too low.
+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.
