+# Password Strength Checker
+
+This is a simple Python script that evaluates the strength of a password based on complexity and security. It checks for various criteria like length, presence of uppercase letters, lowercase letters, digits, and special characters.
+
+## How to Use
+
+1. Run the `password_strength_checker.py` script in your Python environment.
+2. You will be prompted to enter a password for evaluation.
+3. The script will check the password against the following criteria:
+   - At least 8 characters in length.
+   - Contains at least one uppercase letter.
+   - Contains at least one lowercase letter.
+   - Contains at least one digit.
+   - Contains at least one special character (e.g., '@', '_', '!', '#', '$', '%', '^', '&', '*', '(', ')', '<', '>', '?', '/', '|', '}', '{', '~', ':').
+4. Based on the criteria, the script will provide feedback on whether the password is strong or weak.
+
+## Criteria for a Strong Password
+
+To be considered a strong password, the password must meet all of the following conditions:
+1. Be at least 8 characters in length.
+2. Contain at least one uppercase letter.
+3. Contain at least one lowercase letter.
+4. Contain at least one digit.
+5. Contain at least one special character.
+
