-# Contributing Code
-
-PXT accepts bug fix pull requests. For a bug fix PR to be accepted, it must first have a tracking issue that has been marked approved. Your PR should link to the bug you are fixing. If you've submitted a PR for a bug, please post a comment in the bug to avoid duplication of effort.
-
-PXT also accepts new feature pull requests. For a feature-level PR to be accepted, it first needs to have design discussion. Design discussion can take one of two forms a) a feature request in the issue tracker that has been marked as approved or b) the PR must be accompanied by a full design spec and this spec is later approved in the open design discussion. Features are evaluated against their complexity, impact on other features, roadmap alignment, and maintainability.
-
-These two blogs posts on contributing code to open source projects are a good reference: [Open Source Contribution Etiquette](http://tirania.org/blog/archive/2010/Dec-31.html) by Miguel de Icaza and [Don't "Push" Your Pull Requests](https://www.igvita.com/2011/12/19/dont-push-your-pull-requests/) by Ilya Grigorik.
-
-## Security
-
-If you believe you have found a security issue in PXT, please share it with us privately following the guidance at the Microsoft [Security TechCenter](https://technet.microsoft.com/en-us/security/ff852094). Reporting it via this channel helps minimize risk to projects built with PXT.
-
-## Legal
-
-You will need to complete a Contributor License Agreement (CLA) before your pull request can be accepted. This agreement testifies that you are granting us permission to use the source code you are submitting, and that this work is being submitted under appropriate license that we can use it.
-
-You can complete the CLA by going through the steps at https://cla.microsoft.com. Once we have received the signed CLA, we'll review the request. You will only need to do this once.
-
-## Housekeeping
-
-Your pull request should:
-* Include a description of what your change intends to do
-* Be a child commit of a reasonably recent commit in the master branch
-* Pass all unit tests
-* Have a clear commit message
-* Include adequate tests

+# microbit-chrome
+Prototype chrome addon that exposes the micro:bit's serial output to webpages. 
+* watch the [demo video](https://vimeo.com/146207766)
+
+# Installation
+See [developer.chrome.com](https://developer.chrome.com/extensions/getstarted#unpacked)
+for instructions on how to install the local version into your chrome browser.
+
+# Requirements
+* Chrome 48 or later.
+
+# Sample page
+The `demo.html` webpage goes along with the
+https://github.com/Microsoft/microbit-touchdevelop/blob/master/examples/tcs34725.cpp
+program. Run `http-server` from this directory, then visit
+http://localhost:8080/demo.html
+(keep in mind that pages served from `file://` cannot open ports).
+
+# Building
+
+Open a command prompt and run the following commands.
+
+````
+npm install
+typings update
+````

+# About
+
+### @description A Blocks / Javascript code editor for the micro:bit, a pocket-size computer with 5x5 display, sensors and Bluetooth.
+
+The [BBC micro:bit](https://www.microbit.co.uk) is a [pocket-size computer](/device) with a 5x5 display of 25 LEDs, Bluetooth and sensors that can be programmed by anyone.
+The BBC micro:bit was made possible by many [partners](https://www.microbit.co.uk/partners).
+
+The micro:bit provides an easy and fun introduction to programming and making – switch on, program it to do something fun – wear it, customize it.
+Just like Arduino, the micro:bit can be connected to and interact with sensors, displays, and other devices. 
+
+* [Read the docs](/docs)
+
+## [Hardware: The Device](/device)
+
+The BBC micro:bit is packaged with sensors, radio and other goodies. Learn about the [hardware components](/device) of the micro:bit to make the most of it!
+
+## Programming: [Blocks](/blocks) or [JavaScript](/javascript)
+
+You can program the micro:bit using [Blocks](/blocks) or [JavaScript](/javascript) in your web browser via the [micro:bit APIs](/reference):
+
+```block
+input.onButtonPressed(Button.A, () => {
+    basic.showString("Hi!");
+})
+```
+```typescript
+input.onButtonPressed(Button.A, () => {
+    basic.showString("Hi!");
+})
+```
+
+The editor work in [most modern browsers](/browsers), work [offline](/offline) once loaded and do not require any installation. 
+
+## [Compile and Flash: Your Program!](/device/usb)
+
+When you have your code ready, you connect your micro:bit to a computer via a USB cable, so it appears as a mounted drive (named MICROBIT). 
+
+Compilation to ARM thumb machine code from [Blocks](/blocks) or [JavaScript](/javascript) happens in the browser. You save the ARM binary 
+program to a file, which you then copy to the micro:bit drive, which flashes the micro:bit device with the new program.
+
+## Simulator: Test Your Code
+
+You can run your code using the micro:bit simulator, all within the confines of a web browser. 
+The simulator has support for the LED screen, buttons, as well as compass, accelerometer, and digital I/O pins.
+
+```sim
+basic.forever(() => {
+  basic.showString("Hi!");
+})
+input.onButtonPressed(Button.A, () => {
+    led.stopAnimation();
+    basic.showLeds(`
+. . . . .
+. # . # .
+. . . . .
+# . . . #
+. # # # .`);
+});
+input.onButtonPressed(Button.B, () => {
+    led.stopAnimation();
+    basic.showLeds(`
+. # . # .
+# . # . #
+# . . . #
+. # . # .
+. . # . .`);
+});
+```
+
+## C++ Runtime
+
+The [C++ micro:bit runtime](http://lancaster-university.github.io/microbit-docs/), created at [Lancaster University](http://www.lancaster.ac.uk/), provides access to the hardware functions of the micro:bit, 
+as well as a set of helper functions (such as displaying a number/image/string on the LED screen). 
+
+The [micro:bit library](/reference) mirrors the functions of the C++ library. 
+When code is compiled to ARM machine code, the calls to JavaScript micro:bit functions are replaced with calls to the corresponding C++ functions.
+
+## [Command Line Tools](/cli)
+
+Looking to use codethemicrobit.com in your favorite editor? Install the [command line tools](/cli) and get rolling!
+
+## [Packages](/packages)
+
+Create, edit and distribute your own blocks and JavaScript using [packages](/packages). Packages are hosted on GitHub and may be written
+using C++, JavaScript and/or ARM thumb.
+
+## [Open Source](/open-source)
+
+The code for the micro:bit is [open source](/open-source) on GitHub. Contributors are welcome!

+# Boolean
+
+true or false.
+
+A Boolean has one of two possible values: `true`; `false`.  Boolean (logical) operators (*and*, *or*, *not*) take Boolean inputs and yields a Boolean value. Comparison operators on other types ([numbers](/reference/types/number), [strings](/reference/types/string) yields a Boolean value.
+
+The following blocks represent the true and false Boolean values, which can be plugged in anywhere a Boolean value is expected:
+
+```blocks
+true;
+false;
+```
+
+The next three blocks represent the three Boolean (logic) operators:
+
+```blocks
+true && false;
+true || false;
+!true;
+```
+
+The next six blocks represent comparison operators that yield a Boolean value. Most comparisons you will do involve [numbers](/reference/types/number):
+
+```blocks
+42 == 0;
+42 != 0;
+42 < 0;
+42 > 0;
+42 <= 0;
+42 >= 0;
+```
+
+Boolean values and operators are often used with an [if](/blocks/logic/if) or [while](/blocks/loops/while) statement to determine which code will execute next. For example:
+
+### Functions that return a Boolean
+
+Some functions return a Boolean value, which you can store in a Boolean variable. For example, the following code gets the on/off state of `point (1, 2)` and stores this in the Boolean variable named `on`. Then the code clears the screen if `on` is `true`:
+
+### Boolean operators
+
+Boolean operators take Boolean inputs and evaluate to a Boolean output:
+
+### Conjunction: `A and B`
+
+`A and B` evaluates to `true` if-and-only-if both A and B are true:
+
+```blocks
+false && false == false;
+false && true == false;
+true && false == false;
+true && true == true;
+```
+
+### Disjunction: `A or B`
+
+`A or B` evaluates to `true` if-and-only-if either A is true or B is true:
+
+```blocks
+false || false == false;
+false || true == true;
+true || false == true;
+true || true == true;
+```
+
+### Negation: `not A`
+
+`not A` evaluates to the opposite (negation) of A:
+
+```blocks
+!false == true;
+!true == false;
+```
+
+### Example
+
+This example turns on LED `3 , 3`, if LEDs `1 , 1` and `2 , 2` are both on:
+
+```blocks
+if (led.point(1,1) && led.point(2,2)) {
+   led.plot(3,3)
+}
+```
+
+### Comparisons of numbers and strings
+
+When you compare two Numbers, you get a Boolean value, such as the comparison `x < 5` in the code below:
+
+```blocks
+let x = Math.random(5)
+if(x < 5) {
+   basic.showString("low");
+} else { 
+   basic.showString("high");
+} 
+```
+
+See the documentation on [Numbers](/reference/types/number) for more information on comparing two Numbers. You can also [compare strings](/reference/types/string-functions) using the `equals` function.

+# While
+
+Repeat code while a [Boolean](/blocks/logic/boolean) `condition` is true.
+
+```blocks
+while(true) {

+```
+
+The while loop has a *condition* that evaluates to a [Boolean](/blocks/logic/boolean) value. After the `do` keyword, add the code that you want to run while the `condition` is `true`. The while loop concludes with `end while`.
+
+The condition is tested before any code runs. Which means that if the condition is false, the code inside the loop doesn't execute.
+
+### Example: diagonal line
+
+The following example uses a while loop to make a diagonal line on the LED screen (points `0, 0`, `1, 1`, `2, 2`, `3, 3`, `4, 4`).

+# Local Variables
+
+How to define and use local variables.
+
+### @parent language
+
+A variable is a place where you can store and retrieve data. Variables have a name, a [type](/reference/types), and value:
+
+* *name* is how you'll refer to the variable
+* *type* refers to the kind of data a variable can store
+* *value* refers to what's stored in the variable
+
+### Var statement
+
+Use the Block Editor variable statement to create a variable 
+and the [assignment operator](/blocks/variables/assign) 
+to store something in the variable.
+
+For example, this code stores the number `2` in the `x` variable:
+
+```blocks
+let x = 2;
+```
+Here's how to define a variable in the Block Editor:
+
+1. Click `variables`.
+
+2. Change the default variable name if you like.
+
+3. Drag a block type on the right-side of the [assignment operator](/blocks/variables/assign) and click the down arrow to change the variable name.
+
+A variable is created for the number returned by the [brightness](/reference/led/brightness) function.
+
+```blocks
+let b = led.brightness();
+```
+
+### Using variables
+
+Once you've defined a variable, just use the variable's name whenever you need what's stored in the variable. For example, the following code shows the value stored in `counter` on the LED screen:
+
+```blocks
+let counter = 1;
+basic.showNumber(counter);
+```
+
+To change the contents of a variable use the assignment operator. The following code sets `counter` to 1 and then increments `counter` by 10:
+
+```blocks
+let counter = 1;
+counter = counter + 10;
+basic.showNumber(counter);
+```
+
+### Why use variables?
+
+If you want to remember and modify data, you'll need a variable. 
+A counter is a great example:
+
+```blocks
+let counter = 0;
+input.onButtonPressed(Button.A, () => { 
+  counter = counter + 1;
+  basic.showNumber(counter);
+});
+```
+
+### Local variables
+
+Local variables exist only within the function or block of code where they're defined. For example:
+
+```blocks
+// x does NOT exist here.
+if (led.brightness() > 128) {
+  // x exists here
+  let x = 0;
+}
+```
+
+#### Notes
+
+* You can use the default variable names if you'd like, however, it's best to use descriptive variable names. To change a variable name in the editor, select the down arrow next to the variable and then click "new variable".
