# Brand guidelines

Ersilia's brand guidelines were developed by [Forma.co](https://forma.co). You can find an explanation in [this blog post](https://medium.com/ersiliaio/ersilia-open-source-initiative-brand-guidelines-130fe53104f5). The initial thinking on the brand design is summarized in [this presentation](https://drive.google.com/file/d/1EgNbwWsLH9YrZcr-lz1TC12Ns4vvQFUb/view?usp=sharing).
