+# 📌 Model Card: LEGIT-BART Series
+
+## 🏛️ Model Overview
+The **LEGIT-BART** models are a family of **pre-trained transformer-based models** for **Italian legal text processing**. 
+They build upon **BART-IT** ([`morenolq/bart-it`](https://huggingface.co/morenolq/bart-it)) and are further pre-trained on **Italian legal corpora**.
+
+💡 Key features:
+  - **Extended context length** with **Local-Sparse-Global (LSG) Attention** (up to **16,384 tokens**) 📜
+  - **Trained on legal documents** such as **statutes, case law, and contracts** 📑
+  - **Not fine-tuned for specific tasks** (requires further adaptation)
+

+## 🛠️ Model Details
+
+🔹 **Architecture**
+  - Base Model: [`morenolq/bart-it`](https://huggingface.co/morenolq/bart-it)
+  - Transformer Encoder-Decoder
+  - **LSG Attention** for long documents
+  - Specific tokenizers for models trained from scratch (underperforming continual pre-training in our experiments).
+
+🔹 **Training Data**
+  - Dataset: [`joelniklaus/Multi_Legal_Pile`](https://huggingface.co/datasets/joelniklaus/Multi_Legal_Pile)
+  - Types of legal texts used:
+    - **Legislation** (laws, codes, amendments)
+    - **Case law** (judicial decisions)
+    - **Contracts** (public legal agreements)
+

+
+## 🚀 How to Use
+
+```python
+from transformers import BartForConditionalGeneration, AutoTokenizer
+
+# Load tokenizer and model
+model_name = "morenolq/LEGIT-BART"
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+model = BartForConditionalGeneration.from_pretrained(model_name)
+
+# Example input
+input_text = "<mask> 1234: Il contratto si intende concluso quando..."
+inputs = tokenizer(input_text, return_tensors="pt", max_length=4096, truncation=True)
+
+# Generate summary
+summary_ids = model.generate(inputs.input_ids, max_length=150, num_beams=4, early_stopping=True)
+summary = tokenizer.decode(summary_ids[0], skip_special_tokens=True)
+print("📝 Summary:", summary)
+```

+
+⚠️ Limitations & Ethical Considerations
+- **Not fine-tuned for specific tasks**: The models are pre-trained on legal texts and may require further adaptation for specific legal NLP tasks (e.g., summarization, question-answering).
+- **Bias and fairness**: Legal texts may contain biases present in the legal system. Care should be taken to ensure fairness and ethical use of the models.
+- **Legal advice**: The models are not a substitute for professional legal advice. Always consult a qualified legal professional for legal matters.
