 The initial sponsor of the project is the Faculty of Informatics and Information Technologies (FIIT) of the Slovak University of Technology (STU) in Bratislava, Slovakia. [FIIT](https://www.fiit.stuba.sk/en.html?page_id=749)'s contribution has enabled us to layout the groundwork for the course. [Tweede golf](https://tweedegolf.nl/en) and [Rust Edu](https://rust-edu.org/) have also contributed substantially to the creation of Rust 101.
 
 In addition, lead developer Henk has received a grant from the [Rust Foundation](https://foundation.rust-lang.org/).
