+# Getting Started with N1 on Windows
+
+## Dependencies
+1. **Visual Studio**: You must have Visual Studio installed to build native
+extensions. See the notes about Visual Studio below if you encounter compilation
+errors.
+1. **Node**: Node 0.10, 0.11, 0.12, and 4.x supported
+1. **Python 2.7**: The `python` command must be on your `PATH` and must point to
+Python 2.7 (not 3.x)
+1. **Git**: The `git` command must be on your `PATH`
+
+## Building
+
+        git clone https://github.com/nylas/N1.git
+        cd N1
+        script\bootstrap.cmd
+
+## Running
+
+        electron\electron.exe . --dev
+
+# Common Issues:
+While `script\bootstrap.cmd` is designed to work out of the box, we have to
+compile a few native extensions via node-gyp and expect certain programs to be
+available on your `PATH`. If `script\bootstrap.cmd` fails due to a compilation
+error, it is likely due to a Visual Studio problem.
+
+## Visual Studio:
+There are now several versions of Visual Studio. Node-gyp is designed to detect
+the current version installed on your system. If you are using Visual Studio 2015,
+you must be using a newer version of Node.
+
+If during compilation, node-gyp looks in the wrong place for headers, you can
+explicitly set the version of Visual Studio you want it to use by setting the
+`GYP_MSVS_VERSION` environment variable to the year of your Visual Studio version.
+Valid values are `2015`, `2013`, `2013e`, `2012`, etc. (`e` stands for "express").
+The full set of values are [here](https://github.com/nodejs/node/blob/v4.2.1/tools/gyp/pylib/gyp/MSVSVersion.py#L411)
+
+## Node & Npm:
+We only use your system's Node to bootstrap `apm`. Once we have `apm` installed,
+your system's Node no longer matters and we install remaining packages with `apm`.
+
+However, since bootstrapping this requires native extensions to be built, we need
+a version of `node` and `node-gyp` that is compatible with your current Visual Studio
+setup.
+
+There is a small chance that depending on where you setup N1, you will get an
+error about file paths being too long. If this happens, you will need to manually
+install npm 3.x (npm 2.x comes shipped with most Node installations).
+
+Instead of running the whole `script\bootstrap.cmd` script to test this, you can
+`cd` into the `\build` folder, and from there run `npm install`. Only the
+`build\package.json` modules need your system's Node.
+
+## Python:
+The `python` executable must be on your `PATH`. Depending on how you installed Python,
+you may need to ensure the `python.exe` can be found.
