+# jmespath.js
+
+[![Build Status](https://travis-ci.org/jmespath/jmespath.js.png?branch=master)](https://travis-ci.org/jmespath/jmespath.js)
+
+jmespath.js is a javascript implementation of JMESPath,
+which is a query language for JSON.  It will take a JSON
+document and transform it into another JSON document
+through a JMESPath expression.
+
+Using jmespath.js is really easy.  There's a single function
+you use, `jmespath.search`:
+
+
+```
+> var jmespath = require('jmespath');
+> jmespath.search({foo: {bar: {baz: [0, 1, 2, 3, 4]}}}, "foo.bar.baz[2]")
+2
+```
+
+In the example we gave the ``search`` function input data of
+`{foo: {bar: {baz: [0, 1, 2, 3, 4]}}}` as well as the JMESPath
+expression `foo.bar.baz[2]`, and the `search` function evaluated
+the expression against the input data to produce the result ``2``.
+
+The JMESPath language can do a lot more than select an element
+from a list.  Here are a few more examples:
+
+```
+> jmespath.search({foo: {bar: {baz: [0, 1, 2, 3, 4]}}}, "foo.bar")
+{ baz: [ 0, 1, 2, 3, 4 ] }
+
+> jmespath.search({"foo": [{"first": "a", "last": "b"},
+                           {"first": "c", "last": "d"}]},
+                  "foo[*].first")
+[ 'a', 'c' ]
+
+> jmespath.search({"foo": [{"age": 20}, {"age": 25},
+                           {"age": 30}, {"age": 35},
+                           {"age": 40}]},
+                  "foo[?age > `30`]")
+[ { age: 35 }, { age: 40 } ]
+```

+The example above only show a small amount of what
+a JMESPath expression can do.  If you want to take a
+tour of the language, the *best* place to go is the
+[JMESPath Tutorial](http://jmespath.org/tutorial.html).
+
+One of the best things about JMESPath is that it is
+implemented in many different programming languages including
+python, ruby, php, lua, etc.  To see a complete list of libraries,
+check out the [JMESPath libraries page](http://jmespath.org/libraries.html).
