+### Intro
+
+### Préparation des images
+
+- Utiliser le script [scripts/images.py]
+- Entrer les images dans [scripts/sismondi.py]
+
+### Création d'un contrat NFT
+
+Localement sur la chaîne de développement:
+
+```bash
+./brownie.sh run sismondi.py deploy
+```
+
+Avec un `--network sepolia` à la fin, c'est plus sérieux: on va se mettre sur la chaîne de test.
+
+### Minter un NFT
+
+Localement sur la chaîne de développement:
+
+```bash
+./brownie.sh run sismondi.py deploy_mint
+```
+
+Ou sur la chaîne de test:
+
+```bash
+./brownie.sh run sismondi.py mint 0xcontract_id_in_hex --network sepolia

+
+## Installation locale
+
+Pour l'installation locale, il faut commencer à installer docker:
+
+[Commencer avec Docker](https://www.docker.com/get-started/)
+
+Puis on peut préparer l'image avec:
+
+```
+docker compose build
