 # CICD 2022
 
-Bienvenue à cette fabuleuse formation.
+## TP1
 
-Je t'invite à forker le repo et à cloner ton fork sur ta machine.
+Pour lancer l'application python:
 
-## Le sujet du tp
+```bash
+pip install -r requirements.txt
+uvicorn calculator.server:app --reload
+```
 
-Le sujet du tp est de proprifier et tester le code d'une calculatrice en ligne. Une simple page web où on peut entrer une expression mathématique et qui nous donne le résultat.
+## Le Linting
 
-## Pour commencer les tps
+Lorsqu'on travaille en équipe, c'est souvent pratique de garder un code propre. Pour cela, on utilise des outils de linting. Ces outils vont vérifier que le code respecte certaines règles de style. Par exemple, on peut vérifier que les variables sont nommées en snake_case, que les fonctions sont nommées en camelCase, que les fonctions ne font pas plus de 10 lignes, etc.
 
-Les branches `tp1`, `tp2`, `tp3` contiennent les fichiers de base pour chaque tp.
-La correction sont dans les branches `tp1-correction`, `tp2-correction`.
+Un outil qui permet de vérifier le linting de nos application python, c'est pylint. Pour l'installer, on peut utiliser pip:
+
+```bash
+pip install pylint
+```
+
+Pour lancer pylint, on peut utiliser la commande suivante:
+
+```bash
+pylint calculator
+```
+
+Une option intéressante de pylint est le `--fail-on=warning`. Cette option permet de renvoyer une erreur si pylint détecte une erreur. On peut donc l'ajouter à la commande précédente:
+
+```bash
+
+Alors on pourrait fixer les erreurs maintenant, mais on va d'abord vérifier une pipeline avec GitLab.
