@leolara, How best would you fill these fields:

    keywords: ["Reputation", "Identity"],
    themes: ["build"],
    types: ["Infrastructure/protocol"],
    builtWith: ["ethereum attestation service", "halo2", "ethers.rs"],

[leolara]

Check others, and propose what would be the fields in your opinion for chiquito, then we discuss.

[Utilitycoder]

Alright. Look at this draft: https://github.com/Utilitycoder/website-v2/blob/chiquito/data/projects/chiquito.ts
