I have removed all of the installation and getting started stuff from the readme and pointed them to the wiki which is easier to update.

-## INTRODUCTION
+*For installation and other getting started information, see [Getting started with v4](https://theantlrguy.atlassian.net/wiki/display/ANTLR4/Getting+Started+with+ANTLR+v4).*
-
-Hi and welcome to the Honey Badger 4.2.1 release (March 25, 2014) of ANTLR!
-
-## INSTALLATION
-
-### UNIX
-
-0. [Install Java](http://www.oracle.com/technetwork/java/javase/downloads/index.html) (version 1.6 or higher)
-
-1. Download
-   ```sh
-   $ cd /usr/local/lib
-   $ curl -O http://www.antlr4.org/download/antlr-4.2.1-complete.jar
-   ```
-   Or just [download in browser](http://www.antlr.org/download/antlr-4.2.1-complete.jar) and put it somewhere rational like `/usr/local/lib`.
-
-2. Add `antlr-4.2.1-complete.jar` to your `CLASSPATH`:
-   ```sh
-   $ export CLASSPATH=".:/usr/local/lib/antlr-4.2.1-complete.jar:$CLASSPATH"
-   ```
-   Is also a good idea to put this in your .bash_profile or whatever your
-   startup script is.
-
-3. Create aliases for the ANTLR Tool, and TestRig.
-   ```sh
-   $ alias antlr4='java -jar /usr/local/lib/antlr-4.2.1-complete.jar'
-   $ alias grun='java org.antlr.v4.runtime.misc.TestRig'
-   ```
-
-### Windows (Thanks to Graham Wideman)
-
-0. [Install Java](http://www.oracle.com/technetwork/java/javase/downloads/index.html) (version 1.6 or higher)
-
-1. Download [antlr-4.2.1-complete.jar](http://www.antlr.org/download/antlr-4.2.1-complete.jar)
-   Save to your directory for 3rd party Java libraries, say `C:\Javalib`
-
-2. Add `antlr-4.2.1-complete.jar` to `CLASSPATH`, either:
-
- * Permanently: Using System Properties dialog > Environment variables >
-   Create or append to `CLASSPATH` variable
-
- * Temporarily, at command line:
-   `SET CLASSPATH=C:\Javalib\antlr-4.2.1-complete.jar;%CLASSPATH%`
-
-3. Create short convenient commands for the ANTLR Tool, and TestRig,
-   using batch files or doskey commands:
-
- * Batch files (in directory in system `PATH`)
-   ```
-   antlr4.bat: java org.antlr.v4.Tool %*
-   run.bat:   java org.antlr.v4.runtime.misc.TestRig %*
-   ```
-
- * Or, use doskey commands:
-   ```bat
-   doskey antlr4=java org.antlr.v4.Tool $*
-   doskey grun  =java org.antlr.v4.runtime.misc.TestRig $*
-   ```
-
-## Testing installation
-
-Either launch `org.antlr.v4.Tool` directly:
-```sh
-$ java org.antlr.v4.Tool
-ANTLR Parser Generator Version 4.2.1
-    -o ___              specify output directory where all output is generated
-    -lib ___            specify location of .tokens files
-...
-```
-or use `-jar` option on java:
-```sh
-$ java -jar /usr/local/lib/antlr-4.2-complete.jar.1
-ANTLR Parser Generator Version 4.2.1
-    -o ___              specify output directory where all output is generated
-    -lib ___            specify location of .tokens files
-...
-```
-
-## Example
-
-In a temporary directory, put the following grammar inside file `Hello.g4`:
-```g
-// Define a grammar called Hello
-// match keyword hello followed by an identifier
-// match lower-case identifiers
-grammar Hello;
-r : 'hello' ID ;
-ID : [a-z]+ ;
-WS : [ \t\r\n]+ -> skip ; // skip spaces, tabs, newlines
-```
-Then run ANTLR the tool on it:
-```sh
-$ cd /tmp
-$ antlr4 Hello.g4
-$ javac Hello*.java
-```
-Now test it:
-```sh
-$ grun Hello r -tree
-hello parrt
-^D
-(r hello parrt)
-```
-(That `^D` means `EOF` on unix; it's `^Z` in Windows.) The `-tree` option prints the parse tree in LISP notation.
