+
+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

-# micro:bit target for PXT
+# calliope target for PXT
 
-This target allow to program a [BBC micro:bit](https://www.microbit.co.uk/) using 
-[Microsoft Programming Experience Toolkit](https://github.com/Microsoft/pxt).
 
-* [Try it live](https://m.pxt.io)
 
-[![Build Status](https://travis-ci.org/Microsoft/pxt-microbit.svg?branch=master)](https://travis-ci.org/Microsoft/pxt-microbit)
+pxt-calliope is a [Microsoft Programming Experience Toolkit (PXT)](https://github.com/Microsoft/pxt) target that allows you to program a [Calliope mini](https://calliope.cc/en). 
 
-## Local server
 
-### Setup
+* [Try it live](https://makecode.calliope.cc/)
 
-The following commands are a 1-time setup after synching the repo on your machine.
+## Issue tracking
 
-* install the PXT command line
+Please add an issue if you discover an (unreported) bug.
+
+## Developing new extensions
+
+Authoring and testing of new extensions can be done directly from the web editor. See [our documentation](https://makecode.com/blog/github-packages) on how to get started. If you want to run the editor locally, keep reading.
+
+## Local server setup
+
+The local server lets you to run the editor and serve the documentation from your own computer. It is meant for a single developer used and not designed to serve the editor to a large amount of users.
+
+1. Install [Node.js](https://nodejs.org/) 8.9.4 or higher.
+2. Clone this repository.
+```
+git clone https://github.com/microsoft/pxt-calliope
+cd pxt-calliope
+```
+3. Install the PXT command line (add `sudo` for Mac/Linux shells).
 ```
 npm install -g pxt
 ```
-* install the dependencies
+4. Install the pxt-calliope dependencies.
 ```
 npm install
 ```
 
+Go to the **Running** section.
+
+### Developer Setup
+
+This is the typical setup used by the MakeCode team to work on the microbit.
+
+1. Install [Node.js](https://nodejs.org/) 8.9.4 or higher.
+2. Install [Docker](https://www.docker.com/get-started) if you plan to build ``.cpp`` files.
+3. Clone the pxt repository.
+```
+git clone https://github.com/microsoft/pxt
+cd pxt
+```
+4. Install the dependencies of pxt and build it
+```
+npm install
+npm run build
+cd ..
+```
+5. Clone the pxt-common-packages repository
+```
+git clone https://github.com/microsoft/pxt-common-packages
+cd pxt-common-packages
+npm install
+cd ..
+```
+6. Clone this repository.
+```
+git clone https://github.com/microsoft/pxt-calliope
+cd pxt-calliope
+```
+7. Install the PXT command line (add `sudo` for Mac/Linux shells).
+```
+npm install -g pxt
+```
+8. Install the pxt-calliope dependencies.
+```
+npm install
+```
+8. Link pxt-calliope back to base pxt repo (add `sudo` for Mac/Linux shells). 
+This step is only required if you intend to make changes to pxt and/or 
+pxt-common-packages repos. If all you want is serve a local Makecode, you can skip
+this step.
+```
+pxt link ../pxt

 ### Running
 
-Run this command to open a local web server:
+Run this command from inside pxt-calliope to open a local web server
 ```
 pxt serve
 ```
-To make sure you're running the latest tools, run
+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 to modify the `.cpp` files (and have installed yotta), enable yotta compilation using the `--localbuild` flag:
 ```
-npm update
+pxt serve --local
 ```
 
-More instructions at https://github.com/Microsoft/pxt#running-a-target-from-localhost 
+If you want to speed up the build, you can use the ``rebundle`` option, which skips building and simply refreshes the target information
+```
+pxt serve --rebundle
+```
 
-## Universal Windows App
+### Cleaning
 
-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.
+Sometimes, your built folder might be in a bad state, clean it and try again.
+```
+pxt clean
+```
 
-### Building
+### Updates
 
-* 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.
+Make sure to pull changes from all repos regularly. More instructions are at https://github.com/Microsoft/pxt#running-a-target-from-localhost
+
+## Update playlists in markdown
+
+Get a Google API key and store it in the ``GOOGLE_API_KEY`` environment variables (turn on data from the app).
+
+```
+pxt downloadplaylists
+```
+
+## Repos 
+
+The pxt-calliope target depends on several other repos. The main ones are:
+- https://github.com/Microsoft/pxt, the PXT framework
+- https://github.com/Microsoft/pxt-common-packages, common APIs accross various MakeCode editors
+- https://github.com/lancaster-university/microbit, basic wrapper around the DAL

+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# @boardname@ uploader for OS X
+
+![](Microbit Uploader/Assets.xcassets/AppIcon.appiconset/icon_256x256.png)
+
+This project is a clone of the [Windows
+uploader](https://makecode.microbit.org/uploader), but for OS X. Once launched,
+the app runs in your menu bar and will automatically deploy any HEX files to
+your `@boardname@`. Like the Windows version, it is compatible with any browser
+that can run @homeurl@.
+
+## Install the built version
+
+1. Download the latest `.zip` release from the `Release` directory
+2. Unzip it
+3. Drag `Microbit Uploader` to your Applications folder and launch it
+
+## Building
+
+To build the project you'll need a copy of OS X 10.11 or higher and Xcode 8 or
+higher (you may be able to build on earlier OSes or versions of Xcode, but this
+remains untested). Once you have a development environment set up, just build
+and run `Microbit Uploader.xcodeproj`.
+
+## Distributing
+
+1. Open the Xcode project
+2. Product > Archive
+3. Export:
+
+    ![Export](Graphics/export.png)
+
+4. You will then have the option of either signing or not-signing the
+   application:
+
+    a) If you have an Apple developer account, select 'Export a Developer
+       ID-signed Application'
+
+    b) If you don't have a developer ID, select 'Export as a macOS App'
+
+5. Zip the produced app and upload to CDN or equivalent

+    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.

+  <!-- 
+    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.

+
+The [Calliope mini](https://calliope.cc) is a [pocket-size computer]([/device](https://calliope.cc/en/calliope-mini/tech-facts)) with a 5x5 display of 25 LEDs, Bluetooth and sensors that can be programmed by anyone.
+
+The Calliope mini 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 Calliope mini can additionally be connected to and interact with sensors, displays, and other devices. 
+
+* [Read the docs](/docs)
+
+## [Hardware: The Device](/device)
+
+The Calliope mini is packaged with sensors, radio and other goodies. Learn about the [hardware components]([/device](https://calliope.cc/en/calliope-mini/tech-facts)) of the Calliope mini to make the most of it!

+
+## Programming: [Blocks](/blocks) or [JavaScript](/javascript)
+
+You can program the Calliope mini using [Blocks](/blocks) or [JavaScript](/javascript) in your web browser via the [Calliope mini APIs](/reference):
+
+```block
+input.onButtonEvent(Button.A, input.buttonEventValue(ButtonEvent.Down), () => {

+
+## [Compile and Flash: Your Program!](/device/usb)
+
+When you have your code ready, you connect your Calliope mini to a computer via a USB cable, so it appears as a mounted drive (named MINI). If you are using the Calliope mini REV2 you also see another drive (FLASH) that handels up to 25 additional programs.  
+
+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.
