+# Building Apache Pig
+
+## Requirements:
+
+* Unix System
+* JDK 1.7+
+* Ant 1.8.1+
+* Findbugs 3.x+
+* Forrest 0.9 (for building the documentation)
+* Internet connection for first build (to fetch all dependencies)
+
+**Note**: Further down this document you can read about the _ready to run build environment_.
+
+## Building Pig
+
+To compile with Hadoop 1.x 
+
+    ant clean jar piggybank 
+
+To compile with Hadoop 2.x 
+
+    ant clean jar piggybank -Dhadoopversion=23
+
+Building and running the tests needed before submitting a patch.
+For more details https://cwiki.apache.org/confluence/display/PIG/HowToContribute
+    
+    ANT_OPTS='-Djavac.args="-Xlint -Xmaxwarns 1000" -Dhadoopversion=23'
+    ant ${ANT_OPTS} clean piggybank jar compile-test test-commit
+    cd contrib/piggybank/java && ant ${ANT_OPTS} test

+# Ready to run build environment
+The easiest way to get an environment with all the appropriate tools is by means
+of the provided Docker config.
+This requires a recent version of docker ( 1.4.1 and higher are known to work ).
+
+## How it works
+By using the mounted volumes feature of Docker this image will wrap itself around the directory
from which it is started.
+So the files within the docker environment are actually the same as outsite.
+
+A very valid way of working is by having your favourite IDE that has the project 
+open and a commandline into the docker that has the exact right tools to do the full build.
+
+## Using it on Linux:
+Install Docker and run this command:
+
+    $ ./start-build-env.sh
+
+## Using it on Mac:
+First make sure Homebrew has been installed ( http://brew.sh/ )
+    
+    $ brew install docker boot2docker
+    $ boot2docker init -m 4096
+    $ boot2docker start
+    $ $(boot2docker shellinit)
+    $ ./start-build-env.sh
+
+The prompt which is then presented is located at a mounted version of the source tree
+and all required tools for testing and building have been installed and configured.
+
+Note that from within this docker environment you ONLY have access to the source
+tree from where you started. 
+
+## Known issues:
+On Mac with Boot2Docker the performance on the mounted directory is currently extremely slow.
+This is a known problem related to boot2docker on the Mac.
+https://github.com/boot2docker/boot2docker/issues/593
+    This issue has been resolved as a duplicate, and they point to a new feature for utilizing
NFS mounts as the proposed solution:
+
+https://github.com/boot2docker/boot2docker/issues/64
+    An alternative solution to this problem is when you install Linux native inside a virtual
machine and run your IDE and Docker etc in side that VM.
