Add "hello world" instructions

Pls add minimal install instructions including standalone hbase setup:

1) Set hostname (if it's not already set)
on hbase/zookeeper quorum server:
$hostname -f
if it returns "localhost" set hostname to e.g. "myhostname.example.com"
$hostname myhostname.example.com

2) Update /etc/hosts on hbase/zookeeper quorum server
$vi /etc/hosts
<zookeeper ip> myhostname.example.com myhostname

3) Update /etc/hosts on client host (if you run phoenix client on a separate machine):
$vi /etc/hosts
<zookeeper ip> myhostname.example.com myhostname

4) set JAVA_HOME:
e.g. on Mac OSX Lion:
$export JAVA_HOME=`/usr/libexec/java_home -v 1.7`

5) get hbase:
Note: For latest Hbase release see: http://hbase.apache.org/
$wget http://apache.spinellicreations.com/hbase/stable/hbase-0.98.5-hadoop2-bin.tar.gz
$tar xvzf hbase-0.98.5-hadoop2-bin.tar.gz

6) get phoenix:
$git clone -b 4.0 https://github.com/apache/phoenix.git

7) build phoenix:
$cd phoenix
$mvn package -DskipTests -Dhadoop.profile=2
Note: also see http://phoenix.apache.org/building.html

8) copy phoenix core jar to hbase lib directory:
$cp phoenix-core/target/phoenix-core-4.1.0-SNAPSHOT.jar ../hbase-0.98.5-hadoop2/lib/

9) Start hbase in standalone mode:
$cd ../hbase-0.98.5-hadoop2/
$bin/start-hbase.sh
check if running: http://localhost:60010
create a table using hbase shell:
$hbase shell
hbase> create 'demo', 'cf'

10) Create a table in phoenix using sqlline:
$cd ../phoenix
$bin/sqlline.py localhost
phoenix>CREATE TABLE test.orders ( id BIGINT not null primary key, name VARCHAR);
phoenix>UPSERT INTO TEST.ORDERS(ID,NAME) VALUES(123,'foo’);
phoenix>SELECT * FROM test.orders;
