-The Windows 10 app is a [Universal Windows Hosted Web App](https://microsoftedge.github.io/WebAppsDocs/en-US/win10/CreateHWA.htm)
-that wraps ``m.pxt.io`` 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 ``m.pxt.io`` project.
+* 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
+            : 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.

 We will call this “passing control of execution” rather than “passing the ball”.  However, in the world of the micro:bit, the concurrently executing subprograms are not aware of each other, so they don’t actually pass control directly to one another.  Rather they pass control of execution back to the scheduler and the scheduler determines the subprogram to pass control to next.  The programmer inserts a call to the `pause` function to indicate a point in the subprogram where control of execution passes to the scheduler. Also, when a subprogram ends execution, control passes to the scheduler.

 The `forever` loop actually is a function that takes a subprogram (an *Action* in Touch Develop) as a parameter. The function uses the `control -> in background` function of the micro:bit runtime to queue a `while true` loop for execution by the scheduler. The while loop has two statements. The first statement runs the subprogram represented by the `body` parameter. The second statement passes control to the scheduler (requesting to “sleep” for 20 milliseconds).

 As a result, you can easily add a new capability to the micro:bit by just adding a new subprogram.

-### Keeping score
-
-#### ~avatar
-
-To keep track out of how many guesses you've won,
-add these blocks to your coin flipper:
-
-#### ~
-
-```blocks
-input.onButtonPressed(Button.A, () => {
-    game.addScore(1);
-});
-input.onButtonPressed(Button.AB, () => {
-    basic.showNumber(game.score());
-});
-```
-
-These blocks mean that if you press button `A`, you will add `1` to
-your score, and if you press `A` and `B` together, the micro:bit will
-show your score.
-
-When you're done, your coin flipping program should look like this:
-
-```blocks
-input.onButtonPressed(Button.B, () => {
-    if (Math.randomBoolean()) {
-        basic.showString("H");
-    } else {
-        basic.showString("T");
-    }
-});
-input.onButtonPressed(Button.A, () => {
-    game.addScore(1);
-});
-input.onButtonPressed(Button.AB, () => {
-    basic.showNumber(game.score());
-});
-```
-
-Flip until your thumbs get tired!

-## Let's play Rock Paper Scissors!
-
-### ~avatar avatar
-
-Build a Rock Paper Scissors game with the BBC micro:bit!  You can play
-the game with a friend who has it on a micro:bit.  You can also play
-it with friends who are just using their hands.  (The game is built
-like a coin flipper, but with three choices instead of two.)
-
-### ~
-
-## Step 1: Getting started
-
-We want the micro:bit to choose rock, paper, or scissors when you
-shake it.  Try creating an ``on shake`` block so when you shake the
-micro:bit, it will run part of a program.
-
-Clear up the blocks and add the blocks below.
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    
-})
-```
-
-Next, when you shake the micro:bit, it should pick a random number from `0` to `2`
-and store it in the variable `item`.
-
-Add a ``set`` block with a variable. Then add a ``pick random`` block,
-and store the random number in the variable,
-like this:
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-})
-
-```
-
-### ~hint
-No one can predict random numbers. That's what makes them great for Rock Paper Scissors!
-### ~
-
-Each possible number these blocks can make (`0`, `1`, or `2`) means a different picture.
-We will show the right picture for that number on the LED screen.
-
-
-## Step 2: Picking paper
-
-Put an ``if`` block after the ``let`` block that checks whether
-`item` is `0`. Make sure the ``if`` block has an ``else if`` part
-and an ``else`` part.
-
-Next, add a ``show leds`` block that shows a
-picture of a piece of paper:
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-    if (item == 0) {
-        basic.showLeds(`
-            # # # # #
-            # . . . #
-            # . . . #
-            # . . . #
-            # # # # #
-            `)
-    } else if (false) {
-
-    } else {
-
-    }
-})
-```
-
-## Step 3: A random rock
-
-Now we are going to add a new picture for the micro:bit to show
-when another random number comes up.
-
-Make the ``else if`` part check if the variable `item` is `1`.
-Then add a ``show leds`` block with a picture of a rock.
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-    if (item == 0) {
-        basic.showLeds(`
-            # # # # #
-            # . . . #
-            # . . . #
-            # . . . #
-            # # # # #
-            `)
-    } else if (item == 1) {
-        basic.showLeds(`
-            . . . . .
-            . # # # .
-            . # # # .
-            . # # # .
-            . . . . .
-            `)
-    } else {
-
-    }
-})
-```
-
-## Step 4: Suddenly scissors
-
-Add a ``show leds`` block with a picture of scissors to the ``else`` part:
-
-```blocks
-input.onGesture(Gesture.Shake, () => {
-    let item = Math.random(3)
-    if (item == 0) {
-        basic.showLeds(`
-            # # # # #
-            # . . . #
-            # . . . #
-            # . . . #
-            # # # # #
-            `)
-
-    } else if (item == 1) {
-        basic.showLeds(`
-            . . . . .
-            . # # # .
-            . # # # .
-            . # # # .
-            . . . . .
-            `)
-    } else {
-        basic.showLeds(`
-            # # . . #
-            # # . # .
-            . . # . .
-            # # . # .
-            # # . . #
-            `)
-    }
-})
-
-```
-
-### ~hint
-
-You don't need to check if `item` is `2` because `2` is the only number left out of `0`, `1`, and `2`.
-That's why you can use an ``else`` instead of an ``else if``.
-
-### ~
-
-Your game is ready!
-
-Click **Compile** to move your program to the BBC micro:bit!
-
-Have fun!
-
-## Step 5: Are you the greatest?
-
-Here is a way you can make your Rock Paper Scissors game better.
-When button ``A`` is pressed, 
-the micro:bit will add `1` to your score.
-
-Open the ``Game`` drawer, and then add the block ``change score by 1`` to your program,
-like this:
-
-```blocks
-input.onButtonPressed(Button.A, () => {
-    game.addScore(1)
-})
-
-```
-
-## Step 6: Prove you're the greatest!
-
-After your micro:bit can add `1` to the score, show how many wins you have.
-
-```blocks
-input.onButtonPressed(Button.A, () => {
-    game.addScore(1)
-    basic.showString("WINS:")
-    basic.showNumber(game.score())
-})
-```
-## Step 7: Staying honest
-
-Success! Your micro:bit can track wins!
-But what about losses? 
-Use the ``Game`` drawer to subtract `1` from your score when you press button `B`. 
-
-Here are all the blocks you will need:
-
-```shuffle
-input.onButtonPressed(Button.B, () => {
-    game.addScore(-1)
-    basic.showString("LOSSES:")
-    basic.showNumber(game.score())
-})
-```
-Click **Compile** to move your program to the BBC micro:bit!

+
+Buttons are great to build games!
+
+### ~
+
+This program will show the word **ANTEATER** on the LED
+screen when you press button `A`.
+
+```blocks
+input.onButtonPressed(Button.A, () => {
+    basic.showString("ANTEATER");
+});
+```
+
+#### ~hint
+
+The ``showString`` block can show letters, numbers, and punctuation
+on the micro:bit screen.
+
+#### ~
+
+Now try to unscramble these blocks in the editor so that the micro:bit
+shows **BANANA** when you press button `B`.
+
+```shuffle
+input.onButtonPressed(Button.B, () => {
+    basic.showString("BANANA");
+});
+```
+#### ~hint
+
+You can find the letter `B` by clicking the letter `A` on the
+``onButtonPressed`` block.
+
+#### ~
+
+Click **Download** to move your program to the BBC micro:bit!
+
+#### Your turn!
+
+Can you combine these blocks so your program shows your real name
+instead of **ANTEATER** when you press `A`, but _your secret agent
+name_ instead of **BANANA** when you press `B`?
+
+### Pins
+
+You can also use the pins as buttons.  (The pins are the holes in the
+metal stripe at the bottom of the micro:bit board.)  For example, hold
+the ``GND`` button with one hand and touch the ``0`` pin (called
+``P0``) with your other hand to tell the micro:bit you're pressing it.
+
+Unscramble the blocks in the editor to show a heart when you touch
+pin ``P0``.
+
+```shuffle
+input.onPinPressed(TouchPin.P0, () => {
+    basic.showLeds(`
+. # . # .
+# . # . #
+# . . . #
+. # . # .
+. . # . .`);
+});
+```
+Click **Download** to move your program to the BBC micro:bit!
+
+## ~hint
+
+Try this experiment: find a friend and hold hands. Touch the ``GND``
+pin while your friend presses the ``P0`` pin. You should see the
+heart! The electric current is going through your bodies and across
+your handshake to make it happen!
