+## s.stream
+__object s.stream( )__
+
+Returns a Sling stream.
+
+Example stream usage using Sling XHR API:
+
+```javascript
+s.get('https://jsonplaceholder.typicode.com/posts').then(xhrResp => {
+	let postArr = JSON.parse(xhrResp.response);
+	let postStream = s.stream().from(postArr).transform(function(arr) {
+		return arr.filter(v => v.userId === 1);
+	}).transform(function(arr) {
+		return arr.filter(v => v.body.includes('quo'));
+	});
+});
+```
+
+Equivalent stream usage using preexisting stream object and Sling XHR API:
+
+```javascript
+let postStream2 = s.stream();
+postStream2.transform(function(arr) {
+	return arr.filter(v => v.userId === 1);
+}).transform(function(arr) {
+	return arr.filter(v => v.body.includes('quo'));
+});
+
+s.get('https://jsonplaceholder.typicode.com/posts').then(xhrResp => {
+	let postArr = JSON.parse(xhrResp.response);
+	postArr.forEach(post => {
+		postStream2.push(post);
+	});
+});
+```
+
+## Stream Functions
+
+## push
+__object push( value )__
+
+Push a value onto a stream. All transformers automatically called. Transformers are only applied on new data. Returns the stream.
+
+## transform
+__object transform ( function(arrayData) { } )__
+
+Add a new transformer to stream. Is automatically applied to all existing and new data. Returns the stream.
+
+## call
+__object call ( function(arrayData) { } )__
+
+Call a function which operates on the stream's data. Returns the stream.
+
+## getData
+__[] getData( )__
+
+Returns a copy of stream array data.
+
+## clearTransformers
+__object clearTransformers( )__
+
+Clears all transformers acting on the stream. Data will remain in state of last transformation. Returns the stream.
+
+## from
+__object from ( newArray )__
+
