+Before starting, **cglm** provides two kind of transform functions; pre and post. 
+
+Pre functions (`T' = Tnew * T`) are like `glm_translate`, `glm_rotate` which means it will translate the vector first and then apply the model transformation.
+Post functions (`T' = T * Tnew`) are like `glm_translated`, `glm_rotated` which means it will apply the model transformation first and then translate the vector.
+
+`glm_translate`, `glm_rotate` are pre functions and are similar to C++ **glm** which you are familiar with. 
+
+In new versions of **cglm** we added `glm_translated`, `glm_rotated`... which are post functions, 
+they are useful in some cases, e.g. append transform to existing transform (apply/append transform as last transfrom T' = T * Tnew).
+
+Post functions are named after pre functions with `ed` suffix, e.g. `glm_translate` -> `glm_translated`. So don't mix them up.
