+### Method 2: Using the Direct Executable Installer
+> ⚠️ **Note:** Standard `.exe` direct installers are deprecated starting from Python 3.15. For newer versions, please use Method 1.
+
+1. Navigate to the official [Python Downloads page](https://python.org/downloads/).
+2. Select the latest release, or download the [recommended Python 3.13 version](https://www.python.org/downloads/release/python-313/).
+3. Download the **Windows installer** executable (`.exe`).
+4. Double-click the downloaded file to run the installer.
+5. **Crucial:** Ensure you check the box that says **"Add Python to PATH"** before clicking install, then follow the remaining prompts.
+
+---
+
+## macOS Installation
+
+1. **Download the Installer:** Visit the official [Python Downloads page](https://python.org/downloads/) and download the macOS installer package (`.pkg`). The [recommended version is 3.13](https://www.python.org/downloads/release/python-313/).
+2. **Run the Installer:** Open the downloaded `.pkg` file and follow the on-screen installation steps. You will be prompted to enter your Mac's administrator password.
+3. **Install Certificates:** 
+   - Once complete, open your `Applications` folder and locate the newly created `Python 3.x` directory.
+   - Double-click the `Install Certificates.command` file. *This step is required to ensure Python can securely connect to the internet.*
+
+---
+
+## Linux Installation (using pyenv)
+
+For Linux distributions, we recommend using `pyenv`, a robust Python environment manager that functions similarly to Windows' Install Manager.
+
+### 1. Install Dependencies
+Open your terminal and run the appropriate command for your package manager to install the required build dependencies:
+
+* **Ubuntu / Debian / Mint:**
+  ```bash
+  sudo apt update
+  sudo apt install -y git make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev```
+
+
+* **Fedora / RHEL / CentOS:**
+   ```bash
+   sudo dnf groupinstall "Development Tools"
+   sudo dnf install git openssl-devel bzip2-devel libffi-devel readline-devel sqlite-devel xz-devel tk-devel```
+
+* **Arch Linux:**
+   ```bash
+   sudo pacman -S --needed base-devel
+   sudo pacman -S git openssl zlib bzip2 readline sqlite3 libffi xz tk
+   ```
+### 2. Install and Configure pyenv
+ 1. Run the automatic installer script:
+   ```bash
+   curl [https://pyenv.run](https://pyenv.run) | bash
+   ```
+2. Follow the instructions printed in the terminal to add pyenv to your shell profile configurations (e.g., .bashrc or .zshrc).
+3. Restart your terminal or source your profile to apply the changes.
+
+### 3. Install Python
+Install your desired version using pyenv. We recommend version 3.13:
+```bash
+pyenv install 3.13
+pyenv global 3.13
+```
+
+## Visual Studio Code Installation
+Get your development environment ready by installing Visual Studio Code for your platform:
+ * **Windows:** Download via the Microsoft Store Link.
+ * **macOS:** Follow the official macOS Setup Guide.
+ * **Linux:** Follow the official Linux Setup Guide for .deb, .rpm, or Snap packages.
