The mcopy desktop app can be either [installed from a binary (on macOS)](https://github.com/sixteenmillimeter/mcopy/releases) or built from source on any platform that supports node.js and [Electron apps](https://electronjs.org/).
See this helpful document from the [node.js Foundation](https://nodejs.org/en/download/package-manager/) about installing node.js from different package managers.
This will provide more detailed instructions about distro-specific dependencies for node.js and the different packages available.
Use a more current version of node, if available.
At the time of this writing, development is taking place on node.js version `9.7.1`.
#### Arduino firmware
It's recommended that on linux distributions, you have the Arduino IDE installed for debugging and to ensure that your system serial permissions are configured to communicate with the Arduino devices.
#### Binary installation
When installing from the pre-built .deb package, you may have to locate the package after installation using the following command:
```
dpkg -L mcopy-app
```
In the output, you should see an item like `/usr/lib/mcopy-app/mcopy` which is the binary that contains the desktop app. I will improve the Linux build process, but will also accept any PRs which improve it as well.
