+# Build instructions (Windows)
+
+## Prerequisites
+
+* Windows 7 or later
+* Visual Studio 2010 Express or higher
+* [Python 2.7](http://www.python.org/download/releases/2.7/)
+* [node.js](http://nodejs.org/)
+* [git](http://git-scm.com)
+
+The instructions bellow are executed under [cygwin](http://www.cygwin.com),
+but it's not a requirement, you can also build atom-shell under Windows's
+console or other terminals.
+
+The building of atom-shell is done entirely with command line scripts, so you
+can use any editor you like to develop atom-shell, but it also means you can
+not use Visual Studio for the development. Support of building with Visual
+Studio will come in future.
+
+**Note:** Even though Visual Studio is not used for building, it's still
+**required because we need the build toolchains it provided.
+
+## Getting the code
+
+```bash
+$ git clone https://github.com/atom/atom-shell.git
+```
+
+## Bootstrapping
+
+The bootstrap script will download all necessary build dependencies and create
+build project files. Notice that we're using `ninja` to build atom-shell so
+there is no Visual Studio project generated.
+
+```bash
+$ cd atom-shell
+$ python script/bootstrap.py
+```
+
+## Building
+
+Build both Release and Debug targets:
+
+```bash
+$ python script/build.py
+```
+
+You can also only build the Debug target:
+
+```bash
+$ python script/build.py -c Debug
+```
+
+After building is done, you can find `atom.exe` under `out\Debug`.
+
+## Tests
+
+```bash
+$ python script/test.py
+```
