-## Getting Sources
-### macOS, Linux
-```
-git config --global core.autocrlf input
-git clone git@github.com:JetBrains/JetBrainsRuntime.git
-```
-
-### Windows
-<a name="sources-windows"></a>
-```
-git config --global core.autocrlf false
-git clone git@github.com:JetBrains/JetBrainsRuntime.git
-```
-
-## Configuring the Build Environment
-Here are quick per-platform instructions for those who can't wait to get started. 
-Please refer to [OpenJDK build docs](https://openjdk.java.net/groups/build/doc/building.html) for in-depth
-coverage of all the details.
-
-> **_TIP:_**  To get a preliminary report of what's missing, run `./configure` and check its output. 
-> It would usually have a meaningful advice on how to solve the problem.
-
-### Linux (Docker)
-Create a container:
-```
-$ cd jb/project/docker
-$ docker build .
-...
-Successfully built 942ea9900054
-```
-Run these commands in the new container:
-```
-$ docker run -v `pwd`../../../../:/JetBrainsRuntime -it 942ea9900054
-# cd /JetBrainsRuntime
-# git checkout master17
-# sh ./configure
-# make images CONF=linux-x86_64-normal-server-release
-```
-
-### Ubuntu Linux
-Install the necessary tools, libraries, and headers with:
-```
-$ sudo apt-get install autoconf make build-essential libx11-dev libxext-dev libxrender-dev libxtst-dev \
-       libxt-dev libxrandr-dev libcups2-dev libfontconfig1-dev libasound2-dev \
-       java-16-amazon-corretto-jdk
-```
-Then run the following:
-```
-$ cd JetBrainsRuntime
-$ git checkout master17
-$ sh ./configure
-$ make images
-```
-This will build the release configuration under `./build/linux-x86_64-server-release/`.
-
-### Windows
-<a name="build-windows"></a>
-Install the following:
-* [Cygwin x64](http://www.cygwin.com/).
-  Required packages: `autoconf`, `binutils`, `cpio`, `diffutils`, `file`, `gawk`, `gcc-core`, `make`, `m4`, `unzip`, `zip`.  
-  Install those together with Cygwin.
-* [Visual Studio compiler toolset](https://visualstudio.microsoft.com/downloads/).
-  Install with the desktop development kit, which includes Windows SDK and compilers.
-  Visual Studio 2019 is supported by default.
-* Java 16 (for instance, from [AdoptOpenJDK](https://adoptopenjdk.net/installation.html?variant=openjdk16&jvmVariant=hotspot#)).
-  If you have problems while configuring, read [Java tips on Cygwin](http://horstmann.com/articles/cygwin-tips.html).
-
-From the command line: 
-```
-"C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat" amd64
-"c:\Program_Files\cygwin64\bin\mintty.exe" /bin/bash -l
-```
-The first command sets up environment variables, the second starts a Cygwin shell with the proper environment.  
-
-In the Cygwin shell: 
-```
-$ cd JetBrainsRuntime
-$ git checkout master17
-$ bash configure --with-toolchain-version=2019
-$ make images
-```
-This will build the release configuration under `./build/windows-x86_64-server-release/`.
-
-### macOS
-Install the following:
-* Xcode command line developer tools and `autoconf` via [Homebrew](getDpiInfo).
-* Java 16 (for instance, from [AdoptOpenJDK](https://adoptopenjdk.net/installation.html?variant=openjdk16&jvmVariant=hotspot#)).
-
-From the command line:
-```
-$ cd JetBrainsRuntime
-$ git checkout master17
-$ sh ./configure
-$ make images
-```
-This will build the release configuration under `./build/macosx-x86_64-server-release/`.
-
-## Developing
-You can use  [CLion](https://www.jetbrains.com/clion/) to develop native parts of the JetBrains Runtime and
-[IntelliJ IDEA](https://www.jetbrains.com/idea/) for the parts written in Java.
-Both require projects to be created.
-
-### CLion
-Run
-```
-$ make compile-commands
-```
-in the git root and open the resulting `build/.../compile_commands.json` file as a project.
-Then use `Tools | Compilation Database | Change Project Root` to point to git root of this repository.
-
-See also this detailed step-by-step tutorial for all platforms:
-[How to develop OpenJDK with CLion](https://blog.jetbrains.com/clion/2020/03/openjdk-with-clion/).
-
-### IDEA
-Run
-```
-$ sh ./bin/idea.sh
-```
-in the git root to generate project files (add `--help` for options). If you have multiple
-configurations (for example, `release` and `fastdebug`), supply the `--conf <conf_name>` argument.
-Then open the git root directory as a project in IDEA.

 <p>On Windows, it is important that you pay attention to the instructions in the <a href="#special-considerations">Special Considerations</a>.</p>
 <p>Windows is the only non-POSIX OS supported by the JDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. Currently, the only supported such layers are Cygwin and Windows Subsystem for Linux (WSL). (Msys is no longer supported due to a too old bash; msys2 would likely be possible to support in a future version but that would require effort to implement.)</p>
