+- What is Nashorn?
+
+Nashorn is a runtime environment for programs written in ECMAScript 5.1
+that runs on top of JVM.
+
+- How to find out more about ECMAScript 5.1?
+
+The specification can be found at
+
+    http://www.ecma-international.org/publications/standards/Ecma-262.htm
+
+- How to checkout sources of Nashorn project?
+
+Nashorn project uses Mercurial source code control system. You can
+download Mercurial from http://mercurial.selenic.com/wiki/Download
+
+Information about the forest extension can be found at
+
+    http://mercurial.selenic.com/wiki/ForestExtension
+
+and downlaoded using
+
+    hg clone https://bitbucket.org/gxti/hgforest
+
+You can clone Nashorn Mercurial forest using this command:
+
+    hg fclone http://hg.openjdk.java.net/nashorn/jdk8 nashorn~jdk8
+    
+To update your copy of the forest (fwith the latest code:
+
+    (cd nashorn~jdk8 ; hg fpull)
+    
+Or just the nashorn subdirectory with
+
+    (cd nashorn~jdk8/nashorn ; hg pull -u)
+    
+To learn about Mercurial in detail, please visit http://hgbook.red-bean.com.
+
+- How to build?
+
+To build Nashorn, you need to install JDK 8. You may use the Nashorn
+forest build (recommended) or down load from java.net.  You will need to
+set JAVA_HOME environmental variable to point to your JDK installation
+directory.
+
+    cd nashorn~jdk8/nashorn/make
+    ant clean; ant
+
+- How to run?
+
+Use the jjs script (see RELESE_README):
+
+    cd nashorn~jdk8/nashorn
+    sh bin/jjs <your .js file>
+
+Nashorn supports javax.script API. It is possible to drop nashorn.jar in
+class path and request for "nashorn" script engine from
+javax.script.ScriptEngineManager. 
+
+Look for samples under the directory test/src/jdk/nashorn/api/scripting/.
+
+- Documentation
+
+Comprehensive development documentation is found in the Nashorn JavaDoc. You can
+build it using:
+
+    cd nashorn~jdk8/nashorn/make
+    ant javadoc
+    
+after which you can view the generated documentation at dist/javadoc/index.html.
+
+- Running tests
+
+Nashorn tests are TestNG based. Running tests requires downloading the
+TestNG library and placing its jar file into the lib subdirectory:
+
+    # download and install TestNG
+    wget http://testng.org/testng-x.y.z.zip
+    unzip testng-x.y.z.zip
+    cp testng-x.y.z/testng-x.y.z.jar test/lib/testng.jar
+    
+After that, you can run the tests using:
+    cd make
+    ant clean test
+    
+You can also run the ECMA-262 test suite with Nashorn. In order to do
+that, you will need to get a copy of it and put it in
+test/script/external/test262 directory. A convenient way to do it is:
+
+   git clone https://github.com/tc39/test262 test/script/external/test262
+    
+Alternatively, you can check it out elsewhere and make
+test/script/external/test262 a symbolic link to that directory. After
+you've done this, you can run the ECMA-262 tests using:
+
+    cd nashorn~jdk8/nashorn/make
+    ant test262
+
+Ant target to get/update external test suites:
+
+    ant externals
+    ant update-externals
+    
+These tests take time, so we have a parallelized runner for them that
+takes advantage of all processor cores on the computer:
+
+    cd nashorn~jdk8/nashorn/make
+    ant test262parallel
+    
+- How to write your own test?
+
+Nashorn uses it's own simple test framework. Any .js file dropped under
+nashorn/test directory is considered as a test. A test file can
+optionally have .js.EXPECTED (foo.js.EXPECTED for foo.js) associated
+with it. The .EXPECTED file, if exists, should contain the output
+expected from compiling and/or running the test file.
+
+The test runner crawls these directories for .js files and looks for
+JTReg-style @foo comments to identify tests.
+
+    * @test - A test is tagged with @test.
+
+    * @test/fail - Tests that are supposed to fail (compiling, see @run/fail
+      for runtime) are tagged with @test/fail.
+
+    * @test/compile-error - Test expects compilation to fail, compares
+      output.
+
+    * @test/warning - Test expects compiler warnings, compares output.
+
+    * @test/nocompare - Test expects to compile [and/or run?]
+      successfully(may be warnings), does not compare output.
+
+    * @subtest - denotes necessary file for a main test file; itself is not
+      a test.
+
+    * @run - A test that should be run is also tagged with @run (otherwise
+      the test runner only compiles the test).
+
+    * @run/fail - A test that should compile but fail with a runtime error.
+
+    * @run/ignore-std-error - script may produce output on stderr, ignore
+      this output.
+
+    * @argument - pass an argument to script.
+
+    * @option \ - pass option to engine, sample.
+
+/**
+ * @option --dump-ir-graph
+ * @test
