+GLM is a header-only library, and thus does not need to be compiled.  To use GLM, merely include the `<glm/glm.hpp>` header, which provides GLSL's mathematics functionality.

 Core GLM features can be included using individual headers to allow faster user program compilations.

-GLM is a header only library that makes a heavy usage of C++ templates.
+GLM makes heavy use of C++ templates, which may significantly increase the compile time for projects that use GLM.  Hence, source files should only include the GLM headers they actually use.
-This design may significantly increase the compile time for files that use GLM. Hence, it is important to limit GLM inclusion to header and source files that actually use it. Likewise, GLM extensions should be
-included only in program sources using them. 
 
-To further help compilation time, GLM 0.9.5 introduced &lt;glm/fwd.hpp&gt; that provides forward declarations of GLM types.
+To further reduce compilation time, include `<glm/fwd.hpp>`, which provides forward declarations of all types should their full definitions not be needed.

-When &lt;glm/glm.hpp&gt; is included, GLM provides all the GLSL features it implements in C++.
+The `<glm/glm.hpp>` header provides all standard GLSL features.
 
-There is no dependence with external libraries or external headers such as gl.h, [*glcorearb.h*](http://www.opengl.org/registry/api/GL/glcorearb.h), gl3.h, glu.h or windows.h. However, if &lt;boost/static\_assert.hpp&gt;

However, if `<boost/static_assert.hpp>` is included, then [`Boost.StaticAssert`](http://www.boost.org/doc/libs/release/libs/static_assert) will be used to provide compile-time errors.  Otherwise, if using a C++11 compiler, the standard `static_assert` will be used instead. If neither is available, GLM will use its own implementation of `static_assert`.
