-[![Build Status](https://travis-ci.org/Microsoft/kindscript-microbit.svg?branch=master)](https://travis-ci.org/Microsoft/kindscript-microbit)
+* [Try it live](https://codethemicrobit.com)
 
-# Getting started
+[![Build Status](https://travis-ci.org/Microsoft/pxt-microbit.svg?branch=master)](https://travis-ci.org/Microsoft/pxt-microbit)
 
-> If you're making changes to kindscript repository itself, proceed to **Local installation** below.
+## Local server
 
-* Clone this repo and run
+The local server allows to run the editor and the documentation from your computer.
 
+### Setup
+
+The following commands are a 1-time setup after synching the repo on your machine.
+
+* if not yet installed, install [Node.js 4.4.5 or higher](https://nodejs.org/en/download/)
+* [clone this repo](https://help.github.com/articles/cloning-a-repository/) to your computer and go in the project folder
+```
+git clone https://github.com/microsoft/pxt-microbit
+cd pxt-microbit
+```
+* install the PXT command line (add ``sudo`` for Mac/Linux shells).
+```
+npm install -g pxt
+```
+* install the dependencies
 ```
 npm install
 ```
 
-* Install the `KindScript` tool and launch the local server:
+### Running
 
+Run this command to open a local web server (add ``sudo`` for Mac/Linux shells)
 ```
-npm install -g kindscript-cli
-kind serve
+pxt serve
 ```
-To re-build the `built/target.json` file, re-run `kind serve`.
+If the local server opens in the wrong browser, make sure to copy the URL containing the local token. 
+Otherwise, the editor will not be able to load the projects.
 
+If you need modify the `.cpp` files, turn on yotta compilation with the ``-yt`` flag (add ``sudo`` for Mac/Linux shells):
+```
+pxt serve -yt
+```
 
-## Local installation
+## Updates
 
-* Clone and build [KindScript](https://github.com/Microsoft/kindscript) in a `kindscript` folder.
-* Clone this repo  in a `kindscript-microbit` folder next to `kindscript`
+To update your PXT version and make sure you're running the latest tools, run (add ``sudo`` for Mac/Linux shells)
+```
+pxt update
+```
 
-```
-npm install
-```
-* To build and deploy new changes
+More instructions at https://github.com/Microsoft/pxt#running-a-target-from-localhost 
 
-```
-npm install -g kindscript-cli
-cd ../kindscript
-jake
-cd ../kindscript-microbit
-npm link ../kindscript
-```
-* run this command to build and launch a local editor
+## Universal Windows App
 
-```
-kind serve
-```
-* open `localhost:3232` to try your editor!
+The Windows 10 app is a [Universal Windows Hosted Web App](https://microsoftedge.github.io/WebAppsDocs/en-US/win10/CreateHWA.htm)
+that wraps ``codethemicrobit.com`` and provides additional features.
+
+### Building
+
+* Install Visual Studio 2015 Update 2 or higher. Make sure the Windows 10 templates are installed.
+* open the ``win10/app.sln`` solution and launch the ``codethemicrobit`` project.
+
+## Testing
+
+The build automatically runs the following:
+
+* make sure the built-in packages compile
+* `pxt run` in `libs/lang-test*` - this will run the test in command line runner; 
+  there is a number of asserts in both of these
+* `pxt testdir` in `tests` - this makes sure all the files compile and generates .hex files
+* run the TD->TS converter on a number of test scripts from `microbit.co.uk` and make sure the results compile
+
+To test something on the device:
+
+* do a `pxt deploy` in `libs/lang-test*` - they should show `1` or `2` on the screen (and not unhappy face)
+* run `pxt testdir` in `tests` and deploy some of the hex files from `tests/built`
+
+The `lang-test0` source comes from the `pxt-core` package. It's also tested with `pxt run` there.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+# 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.

+# 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".
