-# MangoPasswordGenerator
\ No newline at end of file
+# Mango
+
+---
+
+A simple, easy to use password generator written in Python
+
+## Geting Started
+
+### Character Limits
+
+The first input field is where you specify how many characters you would like to make the password.
+**_We have hard limits of minimum 8 characters and maximum of 32 characters._**
+If you enter a value that is not within this range, you will see that the program does not let you generate a password.
+You are only allowed to enter numerical values into this field. (**0-9**)
+
+### Exclusions
+
+You may specify to the program certain characters you would like excluded from the final generated password.
+
+The current list of available characters that the program can generate are as follows:
+
+- All numbers **[0-9]**
+- Uppercase letters **[A-Z]**
+- Lowercase letters **[a-z]**
+- Various Symbols **[@[]^\_`{|}~:;<=>?/\\]**
+
+### Generating the password
+
+The program will output the password in a text field that will allow you to copy onto the clipboard.
+
+### License
+
+This software uses the GPL-3.0 license.
+You can read more about it [here](https://github.com/BlueberryTechnologies/Mango?tab=GPL-3.0-1-ov-file#).
