-AI image generators work by reading your text and using it to create an image. The text you input is called a ‘[prompt](/write-an-image-generation-prompt)’, and it guides the model towards the type of image that you describe.
-Each AI image generator works slightly differently, but the basic idea is the same: text ➡️ image.
+Note: Midjourney is no longer free as it was in this video demo.
 
 
-**2. Choosing an AI Image Generator**
+## How AI Image Generation Works
 
 AI image generators are tools that utilize trained AI models to create new images. The models are trained on databases of existing artwork. The [most popular AI image generators](/the-best-ai-image-generators) are Midjourney, DALLE-2, and StableDiffusion.

+### Generating Your First AI Image
 
 The exact process will vary depending on the generator you're using, but generally, you can follow the following steps:
-1.	Navigate to the generator’s interface.
-2.	Write a short description of the image you want

+2. Write a short description of the image you want
 (optional: include a [negative prompt](/use-negative-prompting) (specifying what you DON’T want in the image)

-**4. Practice and Refine Your Skills**
+### Practice makes perfect
 
 The more you experiment, the better you'll understand how different inputs affect your results. Try new things and make mistakes – it's all part of the learning process!
