-# Building Skia dependency
-
-When you compile Aseprite with [Skia](https://skia.org) as back-end on
-Windows or macOS, you need to compile a specific version of Skia. In
-the following sections you will find straightforward steps to compile
-Skia.
-
-You can always check the
-[official Skia instructions](https://skia.org/user/build) and select
-the OS you are building for. Aseprite uses the `aseprite-m71` Skia
-branch from `https://github.com/aseprite/skia`.
-
-## Skia on Windows
-
-Download
-[Google depot tools](https://storage.googleapis.com/chrome-infra/depot_tools.zip)
-and uncompress it in some place like `C:\deps\depot_tools`.
-
-[It's recommended to compile Skia with Clang](https://github.com/google/skia/blob/master/site/user/build.md#a-note-on-software-backend-performance)
-to get better performance. So you will need to [download Clang](http://releases.llvm.org/8.0.0/LLVM-8.0.0-win64.exe),
-and install it on a folder like `C:\deps\llvm` (a folder without whitespaces).
-
-Open a [developer command prompt](https://docs.microsoft.com/en-us/dotnet/framework/tools/developer-command-prompt-for-vs)
-or command line (`cmd.exe`) and call:
-
-    call "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\Tools\VsDevCmd.bat" -arch=x64
-
-Then:
-
-    set PATH=C:\deps\depot_tools;%PATH%
-    cd C:\deps\depot_tools
-    gclient sync
-
-(The `gclient` command might print an error like
-`Error: client not configured; see 'gclient config'`.
-Just ignore it.)
-
-    cd C:\deps
-    git clone -b aseprite-m71 https://github.com/aseprite/skia.git
-    cd skia
-    set GIT_EXECUTABLE=git.bat
-    python tools/git-sync-deps
-
-(The `tools/git-sync-deps` will take some minutes because it downloads
-a lot of packages, please wait and re-run the same command in case it
-fails.)
-
-Finally, if you've downloaded Clang, use this command:
-
-    set PATH=C:\deps\llvm\bin;%PATH%
-    gn gen out/Release --args="is_official_build=true skia_use_system_expat=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false target_cpu=""x64"" cc=""clang"" cxx=""clang++"" clang_win=""c:\deps\llvm"" win_vc=""C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC"""
-    ninja -C out/Release skia
-
-If you haven't installed Clang, and want to compile Skia with MSVC
-(anyway it's not recommended because the performance penalty is too
-big), you can use the following commands instead:
-
-    gn gen out/Release --args="is_official_build=true skia_use_system_expat=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false target_cpu=""x64"" win_vc=""C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC"""
-    ninja -C out/Release skia
-
-More information about these steps in the
-[official Skia documentation](https://skia.org/user/build).
-
-## Skia on macOS
-
-These steps will create a `deps` folder in your home directory with a
-couple of subdirectories needed to build Skia (you can change the
-`$HOME/deps` with other directory). Some of these commands will take
-several minutes to finish:
-
-    mkdir $HOME/deps
-    cd $HOME/deps
-    git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
-    git clone -b aseprite-m71 https://github.com/aseprite/skia.git
-    export PATH="${PWD}/depot_tools:${PATH}"
-    cd skia
-    python tools/git-sync-deps
-    gn gen out/Release --args="is_official_build=true skia_use_system_expat=false skia_use_system_icu=false skia_use_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false extra_cflags_cc=[\"-frtti\"]"
-    ninja -C out/Release skia
-
-After this you should have all Skia libraries compiled.  When you
-[compile Aseprite](#compiling), remember to add
-`-DSKIA_DIR=$HOME/deps/skia` parameter to your `cmake` call as
-described in the [macOS details](#macos-details) section.
