+# Skia for Aseprite and laf
+
+**Pre-built binaries of Skia** in the [releases page](https://github.com/aseprite/skia/releases).
+
+Skia is a 2D graphic library developed by Google Inc., you can find
+the official website in [skia.org](https://skia.org).
+
+This fork is used to compile Skia automatically for
+[laf](https://github.com/aseprite/laf) and
+[Aseprite](https://github.com/aseprite/aseprite) using GitHub Actions.
+
+# Building 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](https://github.com/aseprite/aseprite) and
+[laf](https://github.com/aseprite/laf) use the **`aseprite-m81`** branch.
+So remember to checkout that specific branch.
+
+These are the platform-specific steps to compile Skia:
+
+* [Skia on Windows](#skia-on-windows)
+* [Skia on macOS](#skia-on-macos)
+* [Skia on Linux](#skia-on-linux)
+
+After this you should have all Skia libraries compiled. After that,
+when you compile laf or Aseprite remember to add
+`-DSKIA_DIR=$HOME/deps/skia` parameter to your `cmake` call and all
+other parameters.
+
+## 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/9.0.0/LLVM-9.0.0-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-m81 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-x64 --args="is_debug=false is_official_build=true skia_use_system_expat=false skia_use_system_icu=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false skia_use_sfntly=false skia_use_freetype=true skia_use_harfbuzz=true skia_pdf_subset_harfbuzz=true skia_use_system_freetype2=false skia_use_system_harfbuzz=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"" extra_cflags=[""-MT""]"
+    ninja -C out/Release-x64 skia modules
+
+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-x64 --args="is_debug=false is_official_build=true skia_use_system_expat=false skia_use_system_icu=false skia_use_system_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false skia_use_sfntly=false skia_use_freetype=true skia_use_harfbuzz=true skia_pdf_subset_harfbuzz=true skia_use_system_freetype2=false skia_use_system_harfbuzz=false target_cpu=""x64"" win_vc=""C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC"" extra_cflags=[""-MT""]"
+    ninja -C out/Release-x64 skia modules
+
+## 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 $HOME/deps
+    git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
+    git clone -b aseprite-m81 https://github.com/aseprite/skia.git
+    export PATH="${PWD}/depot_tools:${PATH}"
+    cd skia
+    python tools/git-sync-deps
+    gn gen out/Release-x64 --args="is_official_build=true skia_use_system_expat=false skia_use_system_icu=false skia_use_libjpeg_turbo=false skia_use_system_libpng=false skia_use_system_libwebp=false skia_use_system_zlib=false extra_cflags_cc=[\"-frtti\"]"
+    ninja -C out/Release-x64 skia modules
+
+## Skia on Linux
+
+These steps will create a `deps` folder in your home directory with a
+couple of subdirectories needed to build Skia (you can change the
+`$HOME/deps` with other directory). Some of these commands will take
+several minutes to finish:
