+By default `nexe` will attempt to download a pre-built executable. These are listed on the [releases page](https://github.com/nexe/nexe/releases/tag/v3.3.3). The exact version you want may be unavailable or you may want to customize what is built. See `nexe --help` for a list of options available when passing the [`--build`](#build-boolean) option. You will also need to ensure your environment is setup to [build node](https://github.com/nodejs/node/blob/master/BUILDING.md). Note: the `python` binary in your path should be an acceptable version of python 3; you can create a [symlink](https://github.com/nexe/nexe/issues/354#issuecomment-319874486) or use the `--python` parameter (e.g. `nexe --build --python=$(which python3)`).

You will also need to ensure your environment is setup to [build node](https://github.com/nodejs/node/blob/master/BUILDING.md).

+
+### Linux and macOS
+[Prerequisites & details](https://github.com/nodejs/node/blob/master/BUILDING.md#unix-and-macos)
+
+### Windows
+
+The fastest and most reliable way to get started is simply to run the commands below. If you'd rather read the details or perform a manual install of the prerequisites, [you can find that here](https://github.com/nodejs/node/blob/master/BUILDING.md#windows).
+
+The instructions below are the fastest and most reliable method.
+Run the following sets of commands with PowerShell (running as Administrator).
+
+**Install all required build tools (and dependencies):**
+```
+Set-ExecutionPolicy Unrestricted -Force
+iex ((New-Object System.Net.WebClient).DownloadString('https://boxstarter.org/bootstrapper.ps1'))
+get-boxstarter -Force
+Install-BoxstarterPackage https://raw.githubusercontent.com/nodejs/node/master/tools/bootstrap/windows_boxstarter -DisableReboots
+```
+
+**Set config:**
+```
+npm config set msvs_version 2019
+npm config set python python3.8
+```
+Where `2019` is the version of Visual Studio you have (if you have it).
+
+**Notes:**
+- Python 3 and Python 2 can coexist and `nexe` will still work, considering the `set config` area above
+- Don't use `npm install windows-build-tools` unless you're having some type of issue, because the above commands configures and installs the latest/preferred too.
