+visit https://golang.org/ or load doc/install-source.html
+in your web browser.
+
 Our canonical Git repository is located at https://go.googlesource.com/go.
 There is a mirror of the repository at https://github.com/golang/go.

-### Download and Install
-
-#### Binary Distributions
-
-Official binary distributions are available at https://golang.org/dl/.
-
-After downloading a binary release, visit https://golang.org/doc/install
-or load doc/install.html in your web browser for installation
-instructions.
-
-#### Install From Source
-
-If a binary distribution is not available for your combination of
-operating system and architecture, visit
-https://golang.org/doc/install/source or load doc/install-source.html
-in your web browser for source installation instructions.
-
-### Contributing
-
 Go is the work of hundreds of contributors. We appreciate your help!

 To contribute, please read the contribution guidelines:
 	https://golang.org/doc/contribute.html

-Note that the Go project does not use GitHub pull requests, and that
-we use the issue tracker for bug reports and proposals only. See
-https://golang.org/wiki/Questions for a list of places to ask
-questions about the Go language.

+
+## Binary Distribution Notes
+
+If you have just untarred a binary Go distribution, you need to set
+the environment variable $GOROOT to the full path of the go
+directory (the one containing this file).  You can omit the
+variable if you unpack it into /usr/local/go, or if you rebuild
+from sources by running all.bash (see doc/install-source.html).
+You should also add the Go binary directory $GOROOT/bin
+to your shell's path.
+
+For example, if you extracted the tar file into $HOME/go, you might
+put the following in your .profile:
+
+	export GOROOT=$HOME/go
+	export PATH=$PATH:$GOROOT/bin
+
+See https://golang.org/doc/install or doc/install.html for more details.

-Does Go have a runtime?</h3>

-Go does have an extensive library, called the <em>runtime</em>,
-that is part of every Go program.
-The runtime library implements garbage collection, concurrency,
-stack management, and other critical features of the Go language.
-Although it is more central to the language, Go's runtime is analogous
-to <code>libc</code>, the C library.
-</p>
-
-<p>
-It is important to understand, however, that Go's runtime does not
-include a virtual machine, such as is provided by the Java runtime.
-Go programs are compiled ahead of time to native machine code.
-Thus, although the term is often used to describe the virtual
-environment in which a program runs, in Go the word &ldquo;runtime&rdquo;

-// The bug happened like this:
-// 1) The main binary adds an itab for *json.UnsupportedValueError / error
-//    (concrete type / interface type).  This itab goes in hash bucket 0x111.
-// 2) The plugin adds that same itab again.  That makes a cycle in the itab
-//    chain rooted at hash bucket 0x111.
-// 3) The main binary then asks for the itab for *dynamodbstreamsevt.Event /
-//    json.Unmarshaler.  This itab happens to also live in bucket 0x111.
-//    The lookup code goes into an infinite loop searching for this itab.
-// The code is carefully crafted so that the two itabs are both from the
-// same bucket, and so that the second itab doesn't exist in
-// the itab hashmap yet (so the entire linked list must be searched).
