+Single-header file picker library for ImGui.   
+
+Currently, this library is Windows-only. Support for Linux is planned.
+
+# How to use
+
+  This library exposes three functions:  
+
+```
+void renderFilePicker(char* userPath, bool* windowOpen, bool* memoryFreed, int windowFlags);
+```
+
+  Call this function within the render loop providing a pre-allocated buffer of MAX_PATH characters in `userPath`, which will be filled with a UTF-8 string. `windowOpen` must be initially set to `true`, and will set itself to `false` when execution is done. If succesful, your buffer will contain a valid path. `memoryFreed` will be set to `true`, and must be checked once the window is closed to free memory resources acquired by this library.  You can provide `windowFlags` to customize its appearance.
+
+### Window customization flags
+```
+	fp::WindowFlags::FULLSCREEN : Render window in full screen, without decorations.
+```
+
+```
+void freeMemory(bool* memoryFreed);
+```
+
+  Memory resources will be deallocated alongside miscellaneous internal tasks, and `memoryFreed` will be set to `true`.
+
+```
+void setDebugInfo(int debugVerbosity);
+```
+
+  When `FPDEBUG` is enabled, this allows you to configure debug granularity.
+
+### Debug flags
+
+```
+	fp::DebugVerbosity::DIRECTORY 
+	fp::DebugVerbosity::VOLUME 
+	fp::DebugVerbosity::EXTENSION 
+```
+
+# Library dependencies
+
+  - **C++ STL**: This library uses `vector`, `fill` and `w\string`.
+
+# Demo build instructions
+
+## Build requirements
+
+  - [**GLFW v3**](https://github.com/glfw/glfw/releases): used as rendering backend. Executable in releases is compiled with version [`3.3.9`](https://github.com/glfw/glfw/releases/tag/3.3.9).
+  - Developed and tested with `clang` using [**llvm-mingw 20220906**](https://github.com/mstorsjo/llvm-mingw/releases/tag/20220906). Any `MinGW`-backed `clang` compiler should work, but your mileage may vary.
+
+## How to compile
+
+   Download GLFW and pick your libraries according to your toolchain. Then, call your compiler directly specifying both libs needed and your paths to the necessary header and lib files:
+   
+   ```
+   clang++ demo/main.cpp -o demo/demo.exe -L C:/pathtollvmmingw/x86_64-w64-mingw32/bin -I C:\pathtollvmmingw\include -L C:/pathtoglfw/lib-mingw-w64 -I C:\pathtoglfw\include -lglfw3 -l libc++
+   ```
+
+   If you want to statically link:
+   
+   ```
+	clang++ demo/main.cpp -o demo/demo.exe -L C:/pathtoglfw/lib-mingw-w64 -L C:/pathtollvmmingw/x86_64-w64-mingw32/lib -I C:\pathtollvmmingw\include -I C:\pathtoglfw\include -std=c++17 -stdlib=libc++ -rtlib=compiler-rt -static -l glfw3 -l gdi32 -l opengl32 -l user32 -l kernel32 -static-libstdc++
+   ```
+   
+# To-Dos
+
+  - Implement a file watcher to check for changes on the current directory.
+  - Add Linux support.
+  - Allow users to provide their own memory allocations as an option.
