+@section compatibility Compatibility with various OpenGL editions
+
+If any class, function or part of code depends on particular OpenGL edition
+(e.g. only for desktop), use conditional compilation to avoid erors on other
+platforms (see @ref portability-target for more information). Put related
+documentation also into the conditional compilation block and don't forget to
+appropriately mark the class/function (@ref documentation-commands-requires "see below").
+Example:
+@code
+#ifndef MAGNUM_TARGET_GLES
+//
+// @brief Set polygon mode
+//
+// @requires_gl Polygon mode is not available in OpenGL ES.
+//
+void setPolygonMode(PolygonMode mode);
+#endif
