+* Export **nif** shapes to ***obj**
+* Transfer *vertex/normal/texture* coordinates from **obj** to **nif**
+
+## Usage
+```
+$ nifhacks --help
+Janky tool that (sometimes) get things done for your nif-needs
+
+Usage: build/bin/nifhacks [OPTIONS] INPUT OUTPUT
+
+Positionals:
+  INPUT     *.nif *.obj       
+  OUTPUT    *.obj *.nif       
+
+Options:
+  -h,--help                   Print this help message and exit

+```
+
+To export skinned shape (highpoly head)
+```bash
+$ nifhacks -s head.nif head.obj
+```
+
+To import changes back to **nif**. (Your **.nif** file will not be overwritten by default, expect changes in **.nif.nif** file)
+```
+$ nifhacks -s eyes.obj head.nif
+```
+
+## Building
+Aside from c++ build tools you'll need [CMake](https://cmake.org) and [Conan](https://conan.io)
+```bash
+$ git clone --depth 1 https://github.com/Elvyria/nifhacks
+$ cd nifhacks
+$ mkdir build && cd build
+$ conan install .. -s build_type=Release --build=missing
+$ cmake -DCMAKE_BUILD_TYPE=Release ..
+$ cmake --build .
+```
