 ### Compiling
 
-You can compile on both Windows (MinGW) or native Linux system thanks to CMake, you only need to adjust your dependencies on Windows or use Conan packages manager (https://conan.io).
-libpng16-dev distrib package can be used on debian/ubuntu.
-
-To compile, just clone and launch cmake: 
+I've a preference for compiling libraries by hand, mainly for backward compatibility, but I recommend using Conan packages manager (https://conan.io) for simplicity.
 
 ```shell
-cmake .
-make
-make install
-```
-
-On Windows system, I can suggest you to use Conan support to help you with dependencies:
-
-```shell
-mkdir build
+conan install -of build . --build=missing -pr:b=default -pr:h=default
 cd build
-conan install .. --build=missing
-cmake .. -G "MinGW Makefiles"
-make
-```
-
-If you want to do it manually without Conan support, you will probably need to specify the dependency flags for CMake. Ex:
-
-`cmake.exe -D"ZLIB_INCLUDE_DIR=zlib/1.2.12/include" -D"ZLIB_LIBRARY=zlib/1.2.12/lib/libzlib.dll.a" -D"PNG_PNG_INCLUDE_DIR=libpng/1.6.37/include" -D"PNG_LIBRARY=libpng/1.6.37/lib/libpng.dll.a" . -G "MinGW Makefiles"`
-
-We can also use cross-compilation (after installing `mingw64` and `cmake` packages on your distrib):
-
-```shell
-mkdir build && cd build
-cmake -DGNU_HOST=x86_64-w64-mingw32 \
-	-DCMAKE_TOOLCHAIN_FILE=../mingw_cross_toolchain.cmake \
-	-D"ZLIB_INCLUDE_DIR=zlib/1.2.12/include" \
-	-D"ZLIB_LIBRARY=zlib/1.2.12/lib/libzlib.dll.a" \
-	-D"PNG_PNG_INCLUDE_DIR=libpng/1.6.37/include" \
-	-D"PNG_LIBRARY=libpng/1.6.37/lib/libpng.dll.a" \
-	..
+cmake .. -DCMAKE_TOOLCHAIN_FILE=conan_toolchain.cmake -DCMAKE_BUILD_TYPE=Release -G "Unix Makefiles"
 cmake --build .
 ```
+
+On Windows environment, you can use MinGW `-G "MinGW Makefiles"` or Ninja `-G "Ninja"` as CMake generator.
+
+### Compiling (HARDCORE)
+
+If you want to do it manually without Conan, you will probably need to specify the dependency flags for CMake. Ex:
+
+`cmake.exe -D"ZLIB_INCLUDE_DIR=zlib/1.2.13/include" -D"ZLIB_LIBRARY=zlib/1.2.13/lib/libzlib.dll.a" -D"PNG_PNG_INCLUDE_DIR=libpng/1.6.40/include" -D"PNG_LIBRARY=libpng/1.6.40/lib/libpng.dll.a" . -G "MinGW Makefiles"`
+
+I've tested cross-compilation too, but since I want to check that Conan is working properly at each release, I've integrated it into the Jenkins flow using Conan for the cross-abstraction.
