+#### Use CMake to build for WebAssembly
+
+Since math functions like `sinf` is used, this can not be targeted at `wasm32-unknown-unknown`, one of [wasi-sdk](https://github.com/WebAssembly/wasi-sdk) or [emscripten](https://github.com/emscripten-core/emsdk) should be used.
+
+Should note that shared build is not yet supported for WebAssembly.
+
+For [simd128](https://github.com/WebAssembly/simd) support, add `-msimd128` to `CMAKE_C_FLAGS`, in command line `-DCMAKE_C_FLAGS="-msimd128"`.
+
+For tests, the cmake option `CGLM_USE_TEST` would still work, you'll need a wasi runtime for running tests, see our [ci config file](.github/workflows/cmake-wasm.yml) for a detailed example.
+
+##### Use CMake and WASI SDK to build for WebAssembly
+
+```bash
+$ cmake .. \
+  -DCMAKE_TOOLCHAIN_FILE=/path/to/wasi-sdk-19.0/share/cmake/wasi-sdk.cmake \
+  -DWASI_SDK_PREFIX=/path/to/wasi-sdk-19.0
+```
+
+Where `/path/to/wasi-sdk-19.0/` is the path to extracted [wasi sdk](https://github.com/WebAssembly/wasi-sdk).
+
+In this case it would by default make a static build.
+
+##### Use CMake and Emscripten SDK to build for WebAssembly
+
+```bash
+$ emcmake cmake .. \
+  -DCMAKE_EXE_LINKER_FLAGS="-s STANDALONE_WASM" \
+  -DCGLM_STATIC=ON
+```
+
+The `emcmake` here is the cmake wrapper for Emscripten from installed [emsdk](https://github.com/emscripten-core/emsdk).

+Call API
+================================
+
+Call API is pre-built API for making calls from library. It is built on top of the array api. **glmc_** is the namespace for the call api. 
+**c** stands for call. 
+
+You need to built cglm to use call api. See build instructions (:doc:`build`) for more details.
+
+The functions except namespace **glmc_** are same as inline api. See ( :doc:`api_inline_array` ) for more details.
+
+📌 In the future we can define option to forward inline functions or struct api to call api.

+Array API - Inline (Default)
+========================================
+
+This is the default API of *cglm*. All functions are forced to be inlined 
+and struct api, call api uses this inline api to share implementation.
+
+📌 Call api is also array api but it is not inlined. 
+In the future there may be option to forward struct api to call api instead of inline api to reduce binary size if needed.
+
+📌 **USE this API docs for similar functions in struct and call api** 
+
+📌 In struct api you can omit namespace e.g :code:`glms_vec3_dot` can be called as :code:`vec3_dot` in struct api, see :doc:`struct-api` to configure struct api for more details. 
+📌 In struct api functions can return struct/union

+Struct API 
+================================
+
+Struct API is alternative API to array api to use **cglm** with improved type safety and easy to use. 
+Since struct api is built top of array api, every struct API is not documented here. 
+See array api documentation for more information for individual functions.
+
+By default struct api adds `s` suffix to every type name e.g. vec3s, mat4s, versors etc. 
+Also struct api `s` suffix to namespace e.g. `glms_vec3_add`, `glms_mat4_mul` etc.
+
+By starting v0.9.0, struct api namespace is configurable. We can omit **glms_** namespace or 
+even change it with custom name to move existing api integrations to **cglm** more easliy...
+We can also add **s** to functin names if we want e.g. `glms_vec3_add()` -> `vec3_add()` or `vec3s_add()`.
+
+By including **cglm/struct.h** header you will include all struct api. It will also include **cglm/cglm.h** too. 
+Since struct apis are inline you don't need to build or link *cglm* against 
+your project unless if you want to use pre-built call-api too.
+
+Struct API is built top of array api. So you can mix them. 
+Use **.raw** union member to access raw array data to use it with array api. 
+
+Unlike array api ([0], [1], [0][0] ...), it is also possible to use struct api 
+with **.x**, **.y**, **.z**, **.w**, **.r**, **.g**, **.b**, **.a**, **.m00**, **m01**... 
+accessors to access individual elements/properties of vectors and matrices.
+

+- **CGLM_STRUCT_API_NAME_SUFFIX**:  define name suffix, DEFAULT is **empty** e.g defining it as #define CGLM_STRUCT_API_NAME_SUFFIX  s will add s suffix to mat4_mul -> mat4s_mul
