To begin with, let's explore the steps involved in starting a new React Native project.

# Theory
#### 1. Create Project Folder
Begin by creating an empty folder on your machine where you prefer to store your React Native app.
#### 2. Open Folder in IDE
Open this folder in your preferred Integrated Development Environment (IDE). 
#### 3. Run Command to Create Project
Use the following command to initiate a new React Native project:

<!DOCTYPE html>

  <head>
    <meta charset="UTF-8" />
    <link
      rel="stylesheet"

    <div class="text-widget">
      
      <input type="text" class="text-field" id="widget1-text" value="npx create-expo-app ./" />
      <button class="copy-button" onclick="handleClick('widget1-text', 'widget1-notify')">

#### 4. Preview Your App
To see the initial appearance of your app, run the following command in the terminal:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <link
      rel="stylesheet"

#### 5. Choose Viewing Method
- You'll be prompted to choose where to preview your app based on the programs installed on your machine (Xcode or Android Studio);
- Additionally, you can install the Expo app on your smartphone and use the QR code to view the app;
- Another option is to open the app in the browser, but this requires installing additional packages (suggested by the terminal).

In this course, we will use the Xcode Simulator. To open it, we type `i` in the terminal.
