+# Password Validator
+
+This program validates passwords to match specific rules. A valid password is one that conforms to the following rules:
+- Minimum length is 6;
+- Maximum length is 12;
+- Contains at least an uppercase letter or a lowercase letter
+- Contains at least a number;
+- Contains at least a special character (such as @,+,£,$,%,*^,etc);
+- Doesn't contain space(s).
+
+# Prerequisites
+
+It requires no prerequisites, you only need to run the script. If you don't have Python installed, you can visit [here](https://www.python.org/downloads/) to download Python.
+
+# How to run the script
+
+Running the script is pretty easy, open a terminal in the folder where your script is located and run the following command :
+
+`python main.py`
+
+# Sample use of the script
