-# Build scrcpy
-
-Here are the instructions to build _scrcpy_ (client and server).
-
-You may want to build only the client: the server binary, which will be pushed
-to the Android device, does not depend on your system and architecture. In that
-case, use the [prebuilt server] (so you will not need Java or the Android SDK).
-
-[prebuilt server]: #prebuilt-server
-
-
-## Requirements
-
-You need [adb]. It is available in the [Android SDK platform
-tools][platform-tools], or packaged in your distribution (`android-adb-tools`).
-
-On Windows, download the [platform-tools][platform-tools-windows] and extract
-the following files to a directory accessible from your `PATH`:
- - `adb.exe`
- - `AdbWinApi.dll`
- - `AdbWinUsbApi.dll`
-
-The client requires [FFmpeg] and [LibSDL2]. Just follow the instructions.

-[LibSDL2]: https://en.wikipedia.org/wiki/Simple_DirectMedia_Layer
-
-
-
-## System-specific steps
-
-### Linux
-
-Install the required packages from your package manager.
-
-#### Debian/Ubuntu
-
-```bash
-# runtime dependencies
-sudo apt install ffmpeg libsdl2-2.0.0
-
-# client build dependencies
-sudo apt install make gcc pkg-config meson \
-                 libavcodec-dev libavformat-dev libavutil-dev \
-                 libsdl2-dev
-
-# server build dependencies
-sudo apt install openjdk-8-jdk
-```
-
-#### Fedora
-
-```bash
-# enable RPM fusion free
-sudo dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
-
-# client build dependencies
-sudo dnf install SDL2-devel ffms2-devel meson gcc make
-
-# server build dependencies
-sudo dnf install java
-```
-
-
-
-### Windows
-
-#### Cross-compile from Linux
-
-This is the preferred method (and the way the release is built).
-
-From _Debian_, install _mingw_:
-
-```bash
-sudo apt install mingw-w64 mingw-w64-tools
-```
-
-You also need the JDK to build the server:
-
-```bash
-sudo apt install openjdk-8-jdk
-```
-
-Then generate the releases:
-
-```bash
-make -f Makefile.CrossWindows
-```
-
-It will generate win32 and win64 releases into `dist/`.
-
-
-#### In MSYS2
-
-From Windows, you need [MSYS2] to build the project. From an MSYS2 terminal,
-install the required packages:
-
-[MSYS2]: http://www.msys2.org/
-
-```bash
-# runtime dependencies
-pacman -S mingw-w64-x86_64-SDL2 \
-          mingw-w64-x86_64-ffmpeg
-
-# client build dependencies
-pacman -S mingw-w64-x86_64-make \
-          mingw-w64-x86_64-gcc \
-          mingw-w64-x86_64-pkg-config \
-          mingw-w64-x86_64-meson
-```
-
-For a 32 bits version, replace `x86_64` by `i686`:
-
-```bash
-# runtime dependencies
-pacman -S mingw-w64-i686-SDL2 \
-          mingw-w64-i686-ffmpeg
-
-# client build dependencies
-pacman -S mingw-w64-i686-make \
-          mingw-w64-i686-gcc \
-          mingw-w64-i686-pkg-config \
-          mingw-w64-i686-meson
-```
-
-Java (>= 7) is not available in MSYS2, so if you plan to build the server,
-install it manually and make it available from the `PATH`:
-
-```bash
-export PATH="$JAVA_HOME/bin:$PATH"
-```
-
-### Mac OS
-
-Install the packages with [Homebrew]:
-
-[Homebrew]: https://brew.sh/
-
-```bash
-# runtime dependencies
-brew install sdl2 ffmpeg
-
-# client build dependencies
-brew install pkg-config meson
-```
-
-Additionally, if you want to build the server, install Java 8 from Caskroom, and
-make it avaliable from the `PATH`:
-
-```bash
-brew tap caskroom/versions
-brew cask install java8
-export JAVA_HOME="$(/usr/libexec/java_home --version 1.8)"
-export PATH="$JAVA_HOME/bin:$PATH"
-```
-
-### Docker
-
-See [pierlon/scrcpy-docker](https://github.com/pierlon/scrcpy-docker).
-
-
-## Common steps
-
-If you want to build the server, install the [Android SDK] (_Android Studio_),
-and set `ANDROID_HOME` to its directory. For example:
-
-[Android SDK]: https://developer.android.com/studio/index.html
-
-```bash
-export ANDROID_HOME=~/android/sdk
-```
-
-If you don't want to build the server, use the [prebuilt server].
-
-Clone the project:
-
-```bash
-git clone https://github.com/Genymobile/scrcpy
-cd scrcpy
-```
-
-Then, build:
-
-```bash
-meson x --buildtype release --strip -Db_lto=true
-cd x
-ninja
-```
-
-### Run
-
-To run without installing:
-
-```bash
-./run x [options]
-```
-
-
-### Install
-
-After a successful build, you can install _scrcpy_ on the system:
-
-```bash
-sudo ninja install    # without sudo on Windows
-```
-
-This installs two files:
-
- - `/usr/local/bin/scrcpy`
- - `/usr/local/share/scrcpy/scrcpy-server.jar`
-
-Just remove them to "uninstall" the application.
-
-You can then [run](README.md#run) _scrcpy_.
-
-
-## Prebuilt server
-
- - [`scrcpy-server-v1.3.jar`][direct-scrcpy-server].  
-   _(SHA-256: 0f9a5a217f33f0ed7a1498ceb3c0cccf31c53533893aa952e674c1571d2740c1)_
-
-[direct-scrcpy-server]: https://github.com/Genymobile/scrcpy/releases/download/v1.3/scrcpy-server-v1.3.jar
-
-Download the prebuilt server somewhere, and specify its path during the Meson
-configuration:
-
-```bash
-meson x --buildtype release --strip -Db_lto=true \
-    -Dprebuilt_server=/path/to/scrcpy-server.jar
-cd x
-ninja
-sudo ninja install
-```
