_The documentation is not available anymore as the PR was closed or merged._<|||||>Hi @nickprock , I found these typos could you edit the file? Thanks!
- "benifici" --> "benefici"
- "stratergia" --> "strategia"
- "Addestranento" --> "Addestramento"
- "Le [Trainer] API supporta" --> "L'API [Trainer] supporta"
-  Here: "tutti gli iperparametri che puoi impostare" It doesn't seem so clear, I would maybe put it this way:  "tutti gli iperparametri che si possono calibrare". What do you think?
- "nonchè" --> "nonché"
- "funzione [accuratezza](https://huggingface.co/metrics/accuracy)" maybe I would keep the function names in English (i.e., with the original name)
- "maggiorni informazioni" --> "maggiori informazioni"
- "le Keras API" --> "l'API di Keras"
- "Sii sicuro" --> "Assicurati" (for gender neutrality)
- "sepecificare" --> "specificare"
- "Compila e fit" --> "Compilazione e adattamento"
- "Per gli utenti che preferiscono scrivere il loro personale ciclo di addestramento" --> "Per chi preferisse scrivere un proprio ciclo di addestramento personale"
- "pò di memoria" --> "po' di memoria"
- "perchè" --> "perché"
- "adesso sei pronto per addestrare!" --> "adesso possiamo addestrare!"  (for gender neutrality)<|||||>Thanks for the review @mfumanelli :pray:, I fixed them. <|||||>This issue has been automatically marked as stale because it has not had recent activity.
