+### 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 python2.7
+```
+Where `2019` is the version of Visual Studio you have (if you have it).
+
+**Notes:**
+- The above works and has been tested with node.js `14.5.4` and `15.8.0`
+- 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.

 ## Native Modules
 
-TODO
+In order to use native modules, the native binaries must be shipped alongside the binary generated by nexe.
 
-- [ ] Implement support for `node-pre-gyp#find`.
+## Troubleshooting
+
+`Error: Entry file "" not found!` means you need to provide `nexe` with input. Either use `-i` or pipe data to it.

+`Error: https://github.com/nexe/nexe/releases/download/v3.3.3/windows-x64-15.8.0 is not available, create it using the --build flag` or similar message means that it either:
+- You are having networking issues such as the download being blocked
+- You should specify the target so `nexe` knows what version of the executable to use.
+	- See the [releases page](https://github.com/nexe/nexe/releases) to find the executable's version number
+	- Example
+		- `nexe -i "app.js" -r "public/**/*.html" -o "dist/myApp.exe" -t x64-14.15.3`
+		- where `-i` specifies the input, `-r` specifies resources to embed, `-o` specifies the output, `-t` specifies the target.
+	- Alternatively you can compile the executable yourself, see that section for details
