-## 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](http://hg.openjdk.java.net/jdk/jdk11/raw-file/tip/doc/building.html) for in-depth
-coverage of all the details.
+# Configure local build environment
+[OpenJDK build docs](http://hg.openjdk.java.net/jdk/jdk11/raw-file/tip/doc/building.html)  
+Tip for all platforms: run `./configure` and check output.  
+Usually, it has meaningful advice how to solve your problem.
 
-> **_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:
+## Linux (Docker)
 ```
 $ 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 \
-       openjdk-11-jdk
-```
-Then run the following:
+## Linux (Ubuntu 18.10 desktop)
 ```
+$ 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 
+
 $ cd JetBrainsRuntime
 $ sh ./configure --disable-warnings-as-errors
 $ make images
 ```
 
-### 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 2015 is supported by default.
-* [Java 11](https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/downloads-list.html). 
-  If you have problems while configuring, read [Java tips on Cygwin](http://horstmann.com/articles/cygwin-tips.html).

-## 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). Then open the git root directory
-as a project in IDEA.

-Subject: [PATCH 28/30] JBR-3459: Fix race condition in
- ClassLoaderDataGraph::classes_do
-
-InstanceKlass in ClassLoaderData can be uninitialized when
-ClassLoaderDataGraph::classes_do is called. Using
-ClassLoaderDataGraph::dictionary_classes_do is safe but problem is still
-persisting with anonymous classes.

-Subject: [PATCH 29/30] JBR-3867 - update keys of jvmti TAG map after
- redefinition
-
-jdwp keeps relation class_ptr->class_ref in jvmti tag. class_ptr is used
-as a tag key, tag value is refnode. There are new class_ptrs after
-redefinition, therefore jdwp redefinition method update all affected
-keys in the tag map.

+# Vanessa Ogle, The Global Transformation of Time, 1870-1950 (2015), p 33,
+# writes "In 1919, the Gold Coast (Ghana as of 1957) made Greenwich
+# time its legal time and simultaneously legalized a summer time of
+# UTC - 00:20 minutes from March to October."; a footnote lists
+# the ordinance as being dated 1919-11-24.
+# The Crown Colonist, Volume 12 (1942), p 176, says "the Government
+# intend advancing Gold Coast time half an hour ahead of G.M.T.
+# The actual date of the alteration has not yet been announced."
+# These sources are incomplete and contradictory.  Possibly what is
+# now Ghana observed different DST regimes in different years.  For
+# lack of better info, use Shanks except treat the minus sign as a

-# Several of the midnight transitions mentioned above are ambiguous;
-# are they 00:00, 00:00s, 24:00, or 24:00s?  When resolving these ambiguities,

-# Commentary from previous versions is included below, to help explain this.

-# From Tim Parenti (2020-12-05):
-# Although L.N. 31/2017 reads that it "shall come into operation at 2:00 a.m.
-# on 11th March 2018", a precise interpretation here poses some problems.  The
-# order states that "the standard time to be observed throughout the Turks and
-# Caicos Islands shall be the same time zone as the Eastern United States of
-# America" and further clarifies "[f]or the avoidance of doubt" that it
-# "applies to the Eastern Standard Time as well as any changes thereto for
-# Daylight Saving Time."  However, as clocks in Turks and Caicos approached
-# 02:00 -04, and thus the declared implementation time, it was still 01:00 EST
-# (-05), as DST in the Eastern US would not start until an hour later.
-#
-# Since it is unlikely that those on the islands switched their clocks twice in
-# the span of an hour, we assume instead that the adoption of EDT actually took
-# effect once clocks in the Eastern US had sprung forward, from 03:00 -04.
-# This discrepancy only affects the time zone abbreviation and DST flag for the
-# intervening hour, not wall clock times, as -04 was maintained throughout.
