+improvements and bugfixes.
 
-See <https://openjdk.java.net/> for more information about
-the OpenJDK Community and the JDK.
+> **_NOTE_**: This is a **development** branch that is periodically synchronized with 
+> the [OpenJDK master](https://github.com/openjdk/jdk/tree/master) branch.
+> 
+ Release builds are based on these branches:
+ * [jbr11](https://github.com/JetBrains/JetBrainsRuntime/tree/jbr11) (JDK 11)

+
+## 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 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
+# 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
+```
+Get Java 18 (for instance, [Azul Zulu Builds of OpenJDK 18](https://www.azul.com/downloads/?version=java-18-sts&os=linux&package=jdk)).
+
+Then run the following:
+```
+$ cd JetBrainsRuntime
+$ git checkout jbr-dev
+$ 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 18 (for instance, [Azul Zulu Builds of OpenJDK 18](https://www.azul.com/downloads/?version=java-18-sts&os=windows&package=jdk)).
+  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 jbr-dev
+$ 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](https://brew.sh/).
+* Java 18 (for instance, [Azul Zulu Builds of OpenJDK 18](https://www.azul.com/downloads/?version=java-18-sts&os=macos&package=jdk)).
+
+From the command line:
+```
+$ cd JetBrainsRuntime
+$ git checkout jbr-dev
+$ 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.

-/**
- * This class is used to wrap the IntelliJ ant logger in order to provide more meaningful
- * output when building langtools. The basic ant output in IntelliJ can be quite cumbersome to
- * work with, as it provides two separate views: (i) a tree view, which is good to display build task
- * in a hierarchical fashion as they are processed; and a (ii) plain text view, which gives you
- * the full ant output. The main problem is that javac-related messages are buried into the
- * ant output (which is made very verbose by IntelliJ in order to support the tree view). It is
- * not easy to figure out which node to expand in order to see the error message; switching
- * to plain text doesn't help either, as now the output is totally flat.
- *
- * This logger class removes a lot of verbosity from the IntelliJ ant logger by not propagating
- * all the events to the IntelliJ's logger. In addition, certain events are handled in a custom
- * fashion, to generate better output during the build.

+ * </p>
+ * This directory must contain one file with pattern <code>*{openjdk}*.{res}</code> which is considered as a container

+ * <p>
+ * If any of score is less than corresponding reference value by 5% then exit code <code>1</code> is returned otherwise
+ * exit code <code>0</code> is returned.
+ * <p>
+ * Standard output will contain scores in format required for TeamCity charts.

+-----------------------------------------------------------------------
+Introduction
+-----------------------------------------------------------------------
+
+RenderPerfTest is a set of on-screen rendering microbenchmarks  to
+analyze the  performance of Java2D graphical primitives rendering
+
+-----------------------------------------------------------------------
+How To Compile
+-----------------------------------------------------------------------
+
+#> cd RenderPerfTest
+
+The benchmark can be compiled by using either ant:
+
+#> ant
+
+or gnumake (assuming there's 'javac' in the path):
+
+#> gnumake
+
+The jar files will be generated into RenderPerfTest/dist directory.
+
+-----------------------------------------------------------------------
+How To Run RenderPerfTest
+-----------------------------------------------------------------------
+Run all tests
+#> ant run
+  or
+#> java -jar dist/RenderPerfTest.jar
+
+Run particular test cases
+
+#> java -jar dist/RenderPerfTest.jar testWhiteTextBubblesGray ...
