-## Tutorial and Examples
+## Why fork?
+C3 development got kinda stack in time. As Etersoft uses c3 for its projects we decided to fork it and improve it by outselves. All releases from origin will be merged as soon as they are out.
 
-+ [Getting Started](http://c3js.org/gettingstarted.html)
-+ [Examples](http://c3js.org/examples.html)
+## How is this differ?
 
-Additional samples can be found in this repository:
-+ [https://github.com/masayuki0812/c3/tree/master/htdocs/samples](https://github.com/masayuki0812/c3/tree/master/htdocs/samples)
+Our current improvments
 
-You can run these samples as:
-```
-$ cd c3/htdocs
-$ python -m SimpleHTTPServer 8080
-```
+#### Working with data
+
+*chart.loadColumns([[id, values...], [...]])*

+Append given values to sequence
 
-## Using the issue queue
-The [issue queue](https://github.com/masayuki0812/c3/issues) is to be used for reporting defects and problems with C3.js, in addition to feature requests and ideas. It is **not** a catch-all support forum. **For general support enquiries, please use the [Google Group](https://groups.google.com/forum/#!forum/c3js) at https://groups.google.com/forum/#!forum/c3js.** All questions involving the interplay between C3.js and any other library (such as AngularJS) should be posted there first!
+Usage:
+```js
+    // Say data was [0, 50]
+    chart.appendToColumn(['data', 100, 200]);
+    // Now data is [0, 50, 100, 200]
+```
 
-Before reporting an issue, please do the following:
-1. [Search for existing issues](https://github.com/masayuki0812/c3/issues) to ensure you're not posting a duplicate.
+*chart.popFromColumn(id, amount)*
 
-1.  [Search the Google Group](https://groups.google.com/forum/#!forum/c3js) to ensure it hasn't been addressed there already.
+Pops given amount from sequence
 
-1. Create a JSFiddle or Plunkr highlighting the issue. Please don't include any unnecessary dependencies so we can isolate that the issue is in fact with C3. *Please be advised that custom CSS can modify C3.js output!*
+Usage:
+```js
+    // Say data was [0, 100, 200, 300]
+    chart.popFromColumn('data', 2);
+    // Now data is [0, 100]
+```
 
-1. When posting the issue, please use a descriptive title and include the version of C3 (or, if cloning from Git, the commit hash — C3 is under active development and the master branch contains the latest dev commits!), along with any platform/browser/OS information that may be relevant.
+*chart.setValue(id, index, value)*
 
-## Pull requests
-Pull requests are welcome, though please post an issue first to see whether such a change is desirable.
-If you choose to submit a pull request, please do not bump the version number unless asked to, and please include test cases for any new features!
+Sets value for given sequence and index. If no value is presented in index, new value is appended to sequence.
+```js
+    // Say data was [0, 100, 200, 300]
+    chart.setValue('data', 2, 400);
+    // Now data is [0, 100, 400, 300]
 
-## Playground
-Please fork this fiddle:
-+ [http://jsfiddle.net/masayuki0812/7kYJu/](http://jsfiddle.net/masayuki0812/7kYJu/)
+    // Set non-existing value
+    chart.setValue('data', 10, 20);
+    // Now data is [0, 100, 400, 300, 20]
+```
 
-## Dependency
-+ [D3.js](https://github.com/mbostock/d3) `<=3.5.0`
+*chart.getValue(id, index)*

+Gets value for given sequence and index.
+```js
