 # embedDIP
 
-**embedDIP** is a portable, embedded digital image processing library written in C/C++ for use on microcontrollers. It provides foundational and advanced image processing functionality with support for various peripherals.
+Source repository: https://github.com/embeddip/embedDIP
 
----
+embedDIP is a portable digital image processing library for embedded systems. It is written in C and C++ and is intended for microcontroller projects that need image data structures, image processing routines, and board-specific peripheral support.
 
-## License
+The library is used by the example projects for the book *Embedded Digital Image Processing with Microcontrollers*.
 
-This project is licensed under the MIT License. See [LICENSE](LICENSE) for details.
+## Contents
 
----
+- `core/`: core image, error, and memory management interfaces.
+- `imgproc/`: image processing modules, including filtering, thresholding, morphology, color conversion, histograms, segmentation, drawing, compression, and FFT support.
+- `device/`: common camera, display, and serial interfaces.
+- `board/`: board profiles for supported targets.
+- `arch/`: architecture-specific implementations.
+- `wrapper/`: C++ wrapper classes.
+- `docs/`: documentation configuration and support files.
 
-## Author
+## Build
+
+embedDIP is built with CMake. Select the target board, architecture, and CPU through CMake cache variables.
+
+Example for STM32F7:
+
+```bash
+cmake -S . -B build -DEMBEDDIP_TARGET_BOARD=STM32F7 -DEMBEDDIP_ARCH=ARM -DEMBEDDIP_CPU=CORTEX_M7
+cmake --build build
+```
+
+Example for ESP32:
 
-Developed and maintained by [Ozan Durgut](https://github.com/ozan956) for embedded systems and digital image processing research.
+```bash
+cmake -S . -B build -DEMBEDDIP_TARGET_BOARD=ESP32 -DEMBEDDIP_ARCH=XTENSA -DEMBEDDIP_CPU=LX6
+cmake --build build
+```
 
-Feel free to fork, contribute, or suggest enhancements via [issues](https://github.com/EmbedDIP/embedDIP/issues).
+The library can also be included from another CMake project with `add_subdirectory(embedDIP)`.
