+
+This module extends the **Contract** module to enforce a minimum
+contract duration.
+
+It adds a ``min_contract_end_date`` field to contracts. If a user
+attempts to set an end date (e.g., via termination) that is earlier than
+this minimum date, the system automatically extends the end date to the
+minimum required date, ensuring the customer is invoiced for the full
+minimum period.

+
+Usage
+=====
+
+To use this module:
+
+1. Go to **Accounting > Customers > Contracts**.
+2. Open or create a contract.
+3. In the **Dates** section (or wherever the field is placed), set the
+   **Minimum End Date**.
+4. If you try to terminate the contract or set a **Date End** that is
+   **before** this minimum date, the system will automatically correct
+   the **Date End** to match the **Minimum End Date**.
