+#### 📌 Note for experienced developers:
 - Since I'm testing this library in my projects, sometimes bugs occurs; finding that bug[s] and making improvements would be more easy with multiple developer/contributor and their projects or knowledge. Consider to make some tests if you suspect something is wrong and any feedbacks, contributions and bug reports are always welcome.
 
-#### Allocations?
+#### 📌 Allocations?
 `cglm` doesn't alloc any memory on heap. So it doesn't provide any allocator. You should alloc memory for **out** parameters too if you pass pointer of memory location. Don't forget that **vec4** (also quat/**versor**) and **mat4** must be aligned (16-bytes), because *cglm* uses SIMD instructions to optimize most operations if available.
 
-#### Returning vector or matrix... ?
+#### 📌 Returning vector or matrix... ?
 
 **cglm** supports both *ARRAY API* and *STRUCT API*, so you can return structs if you utilize struct api (`glms_`).

 The types used are actually unions that allow access to the same data multiple ways. One of those ways involves anonymous structures, available since C11. MSVC also supports it for earlier C versions out of the box and GCC/Clang do if you enable `-fms-extensions`. To explicitly enable these anonymous structures, `#define CGLM_USE_ANONYMOUS_STRUCT` to `1`, to disable them, to `0`. For backward compatibility, you can also `#define CGLM_NO_ANONYMOUS_STRUCT` (value is irrelevant) to disable them. If you don't specify explicitly, cglm will do a best guess based on your compiler and the C version you're using.

+Clipspace Option[s]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By starting **v0.8.3** cglm provides options to switch between clipspace configurations.
+
+Clipspace related files are located at `include/cglm/[struct]/clipspace.h` but 
+these are included in related files like `cam.h`. If you don't want to change your existing 
+clipspace configuration and want to use different clipspace function like `glm_lookat_zo` or `glm_lookat_lh_zo`...
+then you can include individual headers or just define `CGLM_CLIPSPACE_INCLUDE_ALL` which will iclude all headers for you.
+
+1. **CGLM_CLIPSPACE_INCLUDE_ALL**
+2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
+3. **CGLM_FORCE_LEFT_HANDED**
+
+
+1. **CGLM_CLIPSPACE_INCLUDE_ALL**:
+
+By defining this macro, **cglm** will include all clipspace functions for you by just using
+`#include cglm/cglm.h` or `#include cglm/struct.h` or `#include cglm/call.h`
+
+Otherwise you need to include header you want manually e.g. `#include cglm/clipspace/view_rh_zo.h`
+
+2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
+
+This is similar to **GLM**'s **GLM_FORCE_DEPTH_ZERO_TO_ONE** option. 
+This will set clip space between 0 to 1 which makes **cglm** Vulkan, Metal friendly. 
+
+You can use functions like `glm_lookat_lh_zo()` individually. By setting **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
+functions in cam.h for instance will use `_zo` versions.
+
+3. **CGLM_FORCE_LEFT_HANDED**
+
+Force **cglm** to use the left handed coordinate system by default, currently **cglm** uses right handed coordinate system as default,
+you can change this behavior with this option.
+
+**VERY VERY IMPORTANT:**
+
+Be careful if you include **cglm** in multiple projects.
