– Double-click on a component to open its event editor and write code for events like button clicks.
– Write the main program logic in the code editor. Use Pascal language syntax.

3. **Compiling and Running:**
– Click the green “Run” arrow or press `F9` to compile and run your application.
– Lazarus will compile your code using the Free Pascal compiler and execute the application.

4. **Debugging:**
– Use the integrated debugger to identify and fix issues in your code.
– Set breakpoints by clicking on the left margin in the code editor.

### Additional Features:

1. **Object Inspector:**
– The Object Inspector displays the properties of selected components.
– Modify properties visually or through the Object Inspector.

2. **Component Palette:**
– The Component Palette provides a wide range of components like buttons, labels, edit boxes, etc.
– Customize your UI by dragging components onto the form.

3. **Project Options:**
– Configure project options under “Project” in the menu bar.
– Set compiler options, version information, and other project-specific settings.

4. **Version Control:**
– Lazarus supports version control systems like Git. Integrate your project with version control through the “Project” menu.
