-Welcome to ZooKeeper!
+For the latest information about ZooKeeper, please visit our website at:
 
--------------------
-Documentation
+   http://hadoop.apache.org/zookeeper/
 
-See docs/index.html
+and our wiki, at:
 
-New Users -- see the overview, getting started, and programmer guides
-Existing Users -- if you are upgrading to 3.0 review the releasenotes and 
upgrade guide
+   http://wiki.apache.org/hadoop/ZooKeeper
 
--------------------
-Quick Start
-
-Run "ant" command in this directory to build the server/client. 
"zookeeper-dev.jar" will be output to this directory on a successful build.
-
--------------------
-Starting the server:
-
-1) in the conf directory make a copy of zoo_sample.cfg (ie zoo.cfg) and edit 
as necessary. Default values will support a "standalone" instance.
-
-2) start the server with the following comand line:
-
-java -cp conf:zookeeper-dev.jar:src/java/lib/log4j-1.2.15.jar 
org.apache.zookeeper.server.quorum.QuorumPeerMain conf/zoo.cfg
-
-Notice that the server is picking up the log4j.properties file from the conf 
directory (default).
-
-
------------------------
-Starting a client shell
-
-1) run the following command
-
-java -cp conf:zookeeper-dev.jar:src/java/lib/log4j-1.2.15.jar 
org.apache.zookeeper.ZooKeeperMain <server>:<port>
-
-where server and port correspond to the ZooKeeper configuration.
-
-Notice that the client is picking up the log4j.properties file from the conf 
directory (default).

 INSTALLATION
 
-If you're building the client from a check-out from Source Forge repository, 
you
-need to follow the steps outlined below. If you're building from a project 
source package 
-downloaded from Source Forge please skip to step 3.
-1) do a "ant compile_jute" from the zookeeper top level directory 
(.../trunk/zookeeper).
-   This will create a directory named "generated" under zookeeper/c. 
-2) change directory to the zookeeper/c and do a "autoreconf -i" to bootstrap 
-   autoconf, automake and libtool. Please make sure you have autoconf version 
2.59
-   or greater installed. Skip to step 4.
-3) unzip/untar the source tarball and cd to the zookeeper-x.x.x/ directory
-4) do a "./configure [OPTIONS]" to generate the makefile. See INSTALL for 
general 
-   information about running configure. Additionally, the configure supports 
-   the following options:
-   --enable-debug     enables optimization and enables debug info compiler 
options,
-                      disabled by default
-   --without-syncapi  disables Sync API support; zookeeper_mt library won't be 
built,
-                      enabled by default

    --disable-static   do not build static libraries, enabled by default
    --disable-shared   do not build shared libraries, enabled by default
 5) do a "make" or "make install" to build the libraries and install them. 
-   Alternatively, you can also build and run a unit test suite (and you 
probably should). 
-   Please make sure you have cppunit-1.10.x or higher installed before you 
execute step 4. 
-   Once ./configure has finished, do a "make run-check". It will build the 
libraries, 
-   build the tests and run them.
-6) to generate doxygen documentation do a "make doxygen-doc". All 
documentations will be 
-   placed to a new subfolder named docs. By default only HTML documentation is 
generated.
-   For information on other document formats please use "./configure --help"
