You can obtain a pre-compiled Rolens.app for macOS or installer for Windows from the [release page](https://github.com/garraflavatra/rolens/releases/latest).
Rolens is free and open-source software, which means that you can compile it from source on your own machine by cloning [the repository](https://github.com/garraflavatra/rolens).
If you have Node.js installed, just download the source from GitHub, and run `./build.js`. The install script will check that dependencies are present and build Rolens for you. If you want to build it yourself, please continue reading.
Please see the [advanced build documentation](https://garraflavatra.github.io/rolens/development/advanced-build/) for a more profound insight in the build procedure.
