You can download the latest release for macOS.


You'll need Node.js (which comes with npm) installed on your computer in order to build this application.

Clone method

# Clone the repository
git clone
# Go into the repository
cd vade-mecum-shelf
# Install dependencies
npm install
# Run the application
npm start

Note: to use the clone method, the core tool git must also be installed.

Download method

If you don't wish to clone, you can download the source code, unZip it, then directly run the following commands from a Terminal opened at the resulting vade-mecum-shelf-master folder location:

# Install dependencies
npm install
# Run the application
npm start


Several scripts are also defined in the package.json file to build OS-specific bundles of the application, using the simple yet powerful Electron Packager Node module.
For instance, running the following command (once the dependencies are installed) will create a Vade Mecum version for macOS:

# Build macOS (Darwin) application
npm run build-darwin
