+Simple C and C++ programs, cheats and mini projects.
+
+Larger projects may be in separate dirs.
+
+There may be other compiled languages here for which we don't have much material for a separate dir, specially when we interface that language with C. Ex: Fortran.
+
+Non-portable features shall be clearly separated from portable ones in either:
+
+- ifdef blocks
+- separate files
+- separate directories
+- separate repositories
+
+# Bestof
+
+The most useful sections are currently:
+
+- [c/c.c](c/c.c): C cheatsheet.
+- [c/cpp.cpp](c/cpp.cpp): C++ cheatsheet.
+- `makefile.*`: makefiles that take care of a ton of possibilities.
+
+Other reasonably useful cheats can be found under:
+
+- [opengl/](opengl/)
+- [kde/](kde/)
+
+# Cheatsheets
+
+Everything that can be checked in an assertion will be checked, and will not get printed.
+
+For exemple, a C addition operator `+` test should be done as:
+
+    assert(1 + 1 == 2);
+
+and *never*:
+
+    printf("%d\n", 1 + 1);
+
+so that all can be verified automatically.
+
+Features which yield unpredictable outputs can print results to stdout. For example, `time(NULL)`
+
+    printf("%d\n", 1 + 1);
+
+Features that:
+
+- require user input such as C `scanf`
+- make programs wait for perceptible amounts of time
+
+shall be put inside a block analogous to a `if (0){ ... }` to be turned on only when users want to test those specific features.
+
+Cheat source comments are writen in markdown *indented by headers* and commented out.
+
+Every important keyword that one might search for in the feature has a hash before it, e.g. `#function`, `#include`, `#printf`, etc.
+
+# Contributing
+
+If you find any factual error, or want to include new information, you are more than welcome to send a PR!
