 In the Cygwin shell: 
 ```

 This will build the release configuration under `./build/windows-x86_64-server-release/`.
 
+#### Enable optional NVDA screen reader support
+If you want to add support of a11y announcing via [NVDA screen reader](https://www.nvaccess.org/about-nvda/),
+you will need to bundle the NVDA Controller Client library.
+You can do it with the following steps:
+1. Download the NVDA Controller Client library. You can find the link in its official README [here](https://github.com/nvaccess/nvda/blob/master/extras/controllerClient/readme.md)
+2. Pass the path to the unpacked package to `configure` via an additional flag `--with-nvdacontrollerclient=<path>`.
+   The build system will search the required library files under `<path>/<target-arch>`.
+
+#### Disable optional JAWS screen reader support
+JBR is built with built-in support of JAWS screen reader.
+If you want to disable it, run `configure` with the additional flag `--disable-jaws-client`.
+
 ### macOS
 Install the following:
-* Xcode command line developer tools and `autoconf` via [Homebrew](getDpiInfo).
+* Xcode command line developer tools and `autoconf` via [Homebrew](https://brew.sh/).
 * Java 16 (for instance, from [AdoptOpenJDK](https://adoptopenjdk.net/installation.html?variant=openjdk16&jvmVariant=hotspot#)).
 
 From the command line:
 ```
 $ cd JetBrainsRuntime
-$ git checkout master17
+$ git checkout jbr17
 $ 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.

Currently, the only supported such layers are Cygwin, Windows Subsystem for Linux (WSL), and MSYS2. (MSYS is no longer supported due to an outdated bash; While OpenJDK can be built with MSYS2, support for it is still experimental, so build failures and unusual errors are not uncommon.)</p>
 <p>Internally in the build system, all paths are represented as Unix-style paths, e.g. <code>/cygdrive/c/git/jdk/Makefile</code> rather than <code>C:\git\jdk\Makefile</code>. This rule also applies to input to the build system, e.g. in arguments to <code>configure</code>. So, use <code>--with-msvcr-dll=/cygdrive/c/msvcr100.dll</code> rather than <code>--with-msvcr-dll=c:\msvcr100.dll</code>. For details on this conversion, see the section on <a href="#fixpath">Fixpath</a>.</p>

Note that adding this entitlement makes the build invalid for notarization, so it is only added when signing in <code>debug</code> mode.

To speed up subsequent test runs with no source code changes, <code>test-only</code> can be used instead, which do not depend on the source and test image build.</p>
 <p>For some common top-level tests, direct make targets have been generated. This includes all JTReg test groups, the hotspot gtest, and custom tests (if present). This means that <code>make test-tier1</code> is equivalent to <code>make test TEST=&quot;tier1&quot;</code>, but the latter is more tab-completion friendly. For more complex test runs, the <code>test TEST=&quot;x&quot;</code> solution needs to be used.</p>
 <p>The test specifications given in <code>TEST</code> is parsed into fully qualified test descriptors, which clearly and unambigously show which tests will be run. As an example, <code>:tier1</code> will expand to <code>jtreg:$(TOPDIR)/test/hotspot/jtreg:tier1 jtreg:$(TOPDIR)/test/jdk:tier1 jtreg:$(TOPDIR)/test/langtools:tier1 jtreg:$(TOPDIR)/test/nashorn:tier1 jtreg:$(TOPDIR)/test/jaxp:tier1</code>. You can always submit a list of fully qualified test descriptors in the <code>TEST</code> variable if you want to shortcut the parser.</p>

+<p>Ideally, all tests are run for every change but this may not be practical due to the limited testing resources, the scope of the change, etc.</p>
+<p>The source tree currently defines a few common test groups in the relevant <code>TEST.groups</code> files. There are test groups that cover a specific component, for example <code>hotspot_gc</code>. It is a good idea to look into <code>TEST.groups</code> files to get a sense what tests are relevant to a particular JDK component.</p>
+<p>Component-specific tests may miss some unintended consequences of a change, so other tests should also be run. Again, it might be impractical to run all tests, and therefore <em>tiered</em> test groups exist. Tiered test groups are not component-specific, but rather cover the significant parts of the entire JDK.</p>
+<p>Multiple tiers allow balancing test coverage and testing costs. Lower test tiers are supposed to contain the simpler, quicker and more stable tests. Higher tiers are supposed to contain progressively more thorough, slower, and sometimes less stable tests, or the tests that require special configuration.</p>
+<p>Contributors are expected to run the tests for the areas that are changed, and the first N tiers they can afford to run, but at least tier1.</p>
+<p>A brief description of the tiered test groups:</p>
+<ul>
+<li><p><code>tier1</code>: This is the lowest test tier. Multiple developers run these tests every day. Because of the widespread use, the tests in <code>tier1</code> are carefully selected and optimized to run fast, and to run in the most stable manner. The test failures in <code>tier1</code> are usually followed up on quickly, either with fixes, or adding relevant tests to problem list. GitHub Actions workflows, if enabled, run <code>tier1</code> tests.</p></li>
+<li><p><code>tier2</code>: This test group covers even more ground. These contain, among other things, tests that either run for too long to be at <code>tier1</code>, or may require special configuration, or tests that are less stable, or cover the broader range of non-core JVM and JDK features/components (for example, XML).</p></li>
+<li><p><code>tier3</code>: This test group includes more stressful tests, the tests for corner cases not covered by previous tiers, plus the tests that require GUIs. As such, this suite should either be run with low concurrency (<code>TEST_JOBS=1</code>), or without headful tests (<code>JTREG_KEYWORDS=\!headful</code>), or both.</p></li>
+<li><p><code>tier4</code>: This test group includes every other test not covered by previous tiers. It includes, for example, <code>vmTestbase</code> suites for Hotspot, which run for many hours even on large machines. It also runs GUI tests, so the same <code>TEST_JOBS</code> and <code>JTREG_KEYWORDS</code> caveats apply.</p></li>

 <p>JTReg tests can be selected either by picking a JTReg test group, or a selection of files or directories containing JTReg tests.</p>
 <p>JTReg test groups can be specified either without a test root, e.g. <code>:tier1</code> (or <code>tier1</code>, the initial colon is optional), or with, e.g. <code>hotspot:tier1</code>, <code>test/jdk:jdk_util</code> or <code>$(TOPDIR)/test/hotspot/jtreg:hotspot_all</code>. The test root can be specified either as an absolute path, or a path relative to the JDK top directory, or the <code>test</code> directory. For simplicity, the hotspot JTReg test root, which really is <code>hotspot/jtreg</code> can be abbreviated as just <code>hotspot</code>.</p>
