 Inside of the functions, you can see that we are using `digital_write(led, HIGH)`. This is a function that will enable a pin on the board, and write it high (or low). Since we configured it at the top as `'LED_BUILTIN'`, we will control that LED on the board.
 
 At the bottom of the program, we have something called `start()`. This function will launch the program and concurrently run the `loop()` function.

+## Common Examples
+
+Arduino Runtime was created to simplify the code creation when programming in MicroPython, providing a more user-friendly syntax that allows you to understand the programs you create a bit better.
+
+Now that we have everything installed, and our basic example tested out, let's take a look at some of the more common examples. 
+
+***A list of commands are listed [later in this article](). You can also view the [source code on Github]() for further understanding.***
+
+### Pin Mode
+
+- `pin_mode(pin, mode)`
+
+Configures a pin as an input or an output.
+
+### Analog Read
+
+- `analog_read(pin)`
+
+Analog read is a classic example where you read the voltage from an analog pin.
+
+```python
+pin = "A0"
+
+def setup():
+  print("Analog Read Example")
+
+def loop():
+  value = analog_read(pin)
+  print(value)
+
+start(setup, loop)
+```
+
+### Analog Write (PWM)
+
+- `analog_write(pin, duty_cycle)`
+
+To write an analog signal (using PWM), we can use the `analog_write()` method. This function takes a `pin` and the `duty_cycle` (0-255) as input.
+
+The example below sets the pin to "half capacity", and if you connect an LED to this pin, it will shine at half brightness.
+
+```python
+pin = "D6"
+brightness = 127 #half brightness
+
+def setup():
+    print("Analog Write Example")
+
+def loop():
+    analog_write(pin, brightness)
+
+start(setup, loop)
+```
+
+### Digital Read
+
+- `digital_read(pin)`
+
+Reads a digital pin and returns a HIGH (1) or LOW (0) value.
+
+```python
+def setup():
+    print("Digital Read Example")
+
+def loop():
+    value = digital_read("D2")
+    print(value)
+
+start(setup, loop)
+```
+
+### Digital Write
+
+- `digital_write(pin)`
+
+Writes a HIGH (1) or LOW (0) value to a digital pin.
+
+```python
+def setup():
+    print("Digital Write Example")
+
+def loop():
+    digital_write("D2")
+    
+
+start(setup, loop)
+```
+
+### Delay
+
+- `delay(time)`
+
+Freezes the program for the duration specified in *microseconds*.
+
+Below is a demonstration of the classic blink example:
+
+```python
+led = "D13"
+
+def setup():
+    print("Delay Example")
+    pin_mode(led, OUTPUT)
+
+def loop():
+    digital_write(led, HIGH)
+    delay(1000)
+    digital_write(led, LOW)
+    delay(1000)
+    
+start(setup, loop)
+```
+
+## Runtime Specific Examples
+
+Below are some methods that are introduced with the runtime package.
+
+### Start
+
+- `start(setup, loop, cleanup)`
+
+Starts the program, first by running the `setup()` function, the `loop()` function and finally the `cleanup()` function. 
+
+The `cleanup()` function is optional.
+
+### Cleanup
+
