2. a list of features with bullet points and bold text for the
  application names;
3. a usage section with instructions on how to run the scripts;

+# My PowerShell Scripts
+
+This project provides a collection of PowerShell scripts that students may find useful or life hacking for various applications and tasks.
+
+## Features
+
+Some of the features of the project are:
+
+-   **OneNote**: You can use scripts to automate the creation, editing, and organization of notes, notebooks, and sections in OneNote.
+-   **TheBrain**: You can use scripts to interact with theBrain, a powerful software for mind mapping and knowledge management.
+-   **Windows**: You can use scripts to customize windows settings, create shortcuts, manage updates, and more.
+-   **Bluestacks**: You can use scripts to perform tasks and actions in Bluestacks, an emulator that lets you run Android apps on PC.
+-   **And more**: You can use scripts for other purposes, such as web scraping, file management, text processing, etc.
+
+## Usage
+
+To use the scripts in this project, you need to have PowerShell 5.1 or later installed on your computer. The programs that you wish to use, like OneNote, theBrain, Bluestacks, etc., must also be installed on your PC.
+
+To run a script or function, you can either open PowerShell and type the name of the script or function, or you can right-click on the script file and select “Run with PowerShell”.
