 **Goal:** Build portable/modern framework for web-based BCI applications
 
+Deploying BCI applications in a more portable language such as JavaScript can be difficult as many BCI specific methods have yet to be implemented. WebBCI aims to help bridge this gap by implementing BCI specific methods, building on existing libraries such as Math.js and Numeric Javascript. It also implements MATLAB specific methods, such as colon notation for array subscripting, to make data manipulation in JavaScript easier.
+
+## Dev
+
+This is the dev branch of webbci. Documentation may be lacking and the API can change at any time.
+
 ## Installation
 
 ```bash
-npm install webbci
+npm install webbci@dev
 ```
 
 ## Getting Started
 
+### Signal Processing
+

+### Machine Learning
 
-More examples can be found in the [examples](examples/) directory
+```javascript
+var bci = require('webbci');
+
+// Training set
+var class1 = [
+	[0, 0],
+	[1, 2],
+	[2, 2],
+	[1.5, 0.5]
+];
+var class2 = [

+	return Math.sign(bci.ldaProject(ldaParams, point))
+});
+
+console.log(predictions); // [ -1, -1, -1, 1, 1, 1 ]
+```
+
+### Data Manipulation and Feature Extraction
+
+```javascript
+var bci = require('webbci');
+
+// Some random numbers
+var data = [3, 2, 3, 0, 4, 0, 0, 5, 4, 0];
+
+// Partition into training and testing sets
+var [training, testing] = bci.partition(data, 0.6, 0.4);
+

+console.log(testing); // [0, 5, 4, 0]
+
+// Traverse the data array with windows of size 3 and a step of 2 (overlap of 1 item per window)
+bci.windowApply(data, window => console.log(window), 3, 2);
+/*
+[ 3, 2, 3 ]
+[ 3, 0, 4 ]
+[ 4, 0, 0 ]
+[ 0, 5, 4 ]
+*/
+
+// Find the log of the variance of these windows (feature extraction)
+var features = bci.windowApply(data, bci.features.logvar, 3, 2);
+console.log(features); // [-1.099, 1.466, 1.674, 1.946]
+
+// Colon notation for array subscripting
+var arr = [
+  [1, 2, 3],
+  [4, 5, 6],
+  [7, 8, 9]
+];
+var subarr = bci.subscript(arr, '1 3', '2:3'); // rows 1 and 3, columns 2 through 3
+console.log(subarr);
+/*
+[[2, 3],
+ [8, 9]]
+*/
+```
+
+## Usage in the web
+
+```bash
+npm run dist
+```
+
+This will generate `dist/bci.js` and `dist/bci.min.js`. WebBCI methods can be accessed via the global object *bci*.
+
+OSC methods will not work in the web.

+| step | <code>number</code> |  | The start of the window is incremented by this amount every iteration |
+| tail | <code>boolean</code> | <code>false</code> | If false, windows which begin near the end of the array which cannot reach length 'length' will be ignored |
+
+**Example**  
+```js
+var bci = require('webbci');
+bci.windowApply([1, 2, 3, 4, 5], window => console.log(window), 3, 1);
+// [1, 2, 3]
