 - 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... ?
+Since almost all types are arrays and **C** doesn't allow returning arrays, so **cglm** doesn't support this feature. In the future *cglm* may use **struct** for some types for this purpose.
 
-**cglm** supports both *ARRAY API* and *STRUCT API*, so you can return structs if you utilize struct api (`glms_`).
+#### Other APIs like Vulkan, Metal, Dx?
+Currently *cglm* uses default clip space configuration (-1, 1) for camera functions (perspective, extract corners...), in the future other clip space configurations will be supported

-### Struct API
+## Build
-
-The struct API works as follows, note the `s` suffix on types, the `glms_` prefix on functions and the `GLMS_` prefix on constants:
-
-```C
-#include <cglm/struct.h>
-
-mat4s mat = GLMS_MAT4_IDENTITY_INIT;
-mat4s inv = glms_mat4_inv(mat);
-```
-
-Struct functions generally take their parameters as *values* and *return* their results, rather than taking pointers and writing to out parameters. That means your parameters can usually be `const`, if you're into that.
-
-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.

-## 🔨 Build
-
-### CMake (All platforms)
-```bash
-$ mkdir build
-$ cd build
-$ cmake .. # [Optional] -DCGLM_SHARED=ON
-$ make
-$ sudo make install # [Optional]
-```
-
-##### Cmake options with Defaults:
-
-```CMake
-option(CGLM_SHARED "Shared build" ON)
-option(CGLM_STATIC "Static build" OFF)
-option(CGLM_USE_C99 "" OFF) # C11 
-option(CGLM_USE_TEST "Enable Tests" OFF) # for make check - make test
-```
-
-#### Use as header-only library with your CMake project
-
-This requires no building or installation of cglm.
-
-* Example:
-
-``` cmake
-cmake_minimum_required(VERSION 3.8.2)
-
-project(<Your Project Name>)
-
-add_executable(${PROJECT_NAME} src/main.c)
-target_link_libraries(${LIBRARY_NAME} PRIVATE
-  cglm_headers)
-
-add_subdirectory(external/cglm/ EXCLUDE_FROM_ALL)
-```
-
-#### Use with your CMake project
-* Example:
-```cmake
-cmake_minimum_required(VERSION 3.8.2)
-

-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.

-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.
-
 SSE and SSE2 Shuffle Option
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 **_mm_shuffle_ps** generates **shufps** instruction even if registers are same.
 You can force it to generate **pshufd** instruction by defining
 **CGLM_USE_INT_DOMAIN** macro. As default it is not defined.
-
-SSE3 and SSE4 Dot Product Options
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-You have to extra options for dot product: **CGLM_SSE4_DOT** and **CGLM_SSE3_DOT**.
-
-- If **SSE4** is enabled then you can define **CGLM_SSE4_DOT** to force cglm to use **_mm_dp_ps** instruction.
-- If **SSE3** is enabled then you can define **CGLM_SSE3_DOT** to force cglm to use **_mm_hadd_ps** instructions.
-
-otherwise cglm will use custom cglm's hadd functions which are optimized too.
-
-Print Options
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-1. **CGLM_DEFINE_PRINTS**
-2. **CGLM_NO_PRINTS_NOOP** (use CGLM_DEFINE_PRINTS)
-
-Inline prints are only enabled in **DEBUG** mode or if **CGLM_DEFINE_PRINTS** is defined.
-**glmc_** versions will always print too.
-
-Because **cglm** tried to enable print functions in debug mode and disable them in
-release/production mode to eliminate printing costs when we do not need them.
-
-**cglm** checks **DEBUG** or **_DEBUG** macros to test debug mode, if these are not working for you then you can use 
-**CGLM_DEFINE_PRINTS** to force enable, or create a PR to introduce new macro to test against debugging mode.
-
-If DEBUG mode is not enabled then print functions will be emptied to eliminate print function calls.
-You can disable this feature too by defining **CGLM_DEFINE_PRINTS** macro top of cglm header 
-or in project/build settings...
-
-3. **CGLM_PRINT_PRECISION**    5
-
-precision.
-
-4. **CGLM_PRINT_MAX_TO_SHORT** 1e5
-
-if a number is greater than this value then %g will be used, since this is shorten print you won't be able to see high precision.
-
-5. **CGLM_PRINT_COLOR**        "\033[36m"
-6. **CGLM_PRINT_COLOR_RESET**  "\033[0m"
-
-You can disable colorful print output by defining **CGLM_PRINT_COLOR** and **CGLM_PRINT_COLOR_RESET** as empty macro.
-Because some terminals may not support colors.
