+```
+
+## Additional Dependencies
+### Skia
+If you distro ships this already (e.g. `skia-sharp` on Alpine), you can just install the package and skip this step.
+
+Install `gn` via your system's package manager.
+```sh
+git clone https://github.com/Mis012/skia.git -b with-patches-applied
+cd skia
+cp build/linux-self-hosted/DEPS DEPS
+python3 tools/git-sync-deps
+export arch=x64
+gn gen 'out/linux/$arch' --args='is_official_build=true skia_enable_tools=false target_os="linux" target_cpu="$arch" skia_use_icu=false skia_use_sfntly=false skia_use_piex=true skia_use_system_harfbuzz=true skia_use_system_expat=true skia_use_system_freetype2=true skia_use_system_libjpeg_turbo=true skia_use_system_libpng=true skia_use_system_libwebp=true skia_use_system_zlib=true skia_enable_gpu=true extra_cflags=[ "-DSKIA_C_DLL" ] linux_soname_version="99.9"'
+ninja -C 'out/linux/$arch' SkiaSharp
+sudo cp out/linux/$arch/libSkiaSharp.so.99.9 /usr/local/lib64/
+sudo ln -s /usr/local/lib64/libSkiaSharp.so.99.9 /usr/local/lib64/libSkiaSharp.so
+```
+Note:
+- You can also use [this nuget package](https://www.nuget.org/api/v2/package/SkiaSharp.NativeAssets.Linux/2.88.5) if it's compatible with your distro. It's an older upstream version before the ABI break which is fixed in our skia repository.
+- For `x86` or `aarch64`: set `arch` accordingly.
+- On alpine: add `-fpermissive` to `--args`.
+
+### wolfSSL
+If you distro ships wolfSSL with JNI enabled already, you can just install the package and skip this step.
+```sh
+git clone https://github.com/wolfSSL/wolfssl.git
+cd wolfssl
+git checkout v5.7.0-stable
+autoreconf -i
+./configure --enable-shared --disable-opensslall --disable-opensslextra --enable-aescbc-length-checks --enable-curve25519 --enable-ed25519 --enable-ed25519-stream --enable-oldtls --enable-base64encode --enable-tlsx --enable-scrypt --disable-examples --enable-crl --with-rsa --enable-certs --enable-session-certs --enable-encrypted-keys --enable-cert-gen --enable-cert-ext --enable-clr-monitor --enable-jni
+make
+sudo make install
+```
+
+### bionic_translation
+If you distro ships this already (e.g. `bionic_translation` on Alpine), you can just install the package and skip this step.
+```sh
+git clone https://gitlab.com/android_translation_layer/bionic_translation.git
+cd bionic_translation
+meson setup builddir
+cd builddir
+meson compile
+sudo meson install
+```
+
+### art_standalone
+If you distro ships this already (e.g. `art_standalone` on Alpine), you can just install the package and skip this step.
+```sh
+git clone https://gitlab.com/android_translation_layer/art_standalone.git
+cd art_standalone
+make ____LIBDIR=lib
+sudo make ____LIBDIR=lib install
+```
+Note: adjust `____LIBDIR` depending on your distro (e.g some distros use `lib32`,`lib` or `lib`,`lib64` for multilib).
+
+### libOpenSLES
+Optional (not required for Android Translation Layer itself but some apps depend on it).
+
+If you distro ships this already (e.g. `libopensles-standalone` on Alpine), you can just install the package and skip this step.
+```sh
+git clone https://gitlab.com/android_translation_layer/libopensles-standalone.git
+cd libopensles-standalone
+meson setup builddir
+cd builddir
+meson compile
+sudo meson install
+```
+
