OpenVeo requires and is tested on:

• Node.js (>16.3.0) - The server side of OpenVeo is written in Node.js
• Npm (>=7.15.1) - NPM will help you install all OpenVeo dependencies
• MongoDB (>=4.2.0) - OpenVeo stores all its datas inside a MongoDB database (users, roles, taxonomies etc.)

NB: Moreover, for a Windows installation, Visual Studio Express is required as some OpenVeo dependencies are written in C and need to be compiled. For Linux you may have to install the package libkrb5-dev.
