+## Embeddings
+
+Otherwise known as Textual Inversons, embeddings can help create specfiic results in an image. Place embeddings in the `embeddings` folder and use them in prompts with `embedding:<filename>`. The extension isn't required. Note the lack of space after the `:`. Embeddings don't have a GUI element or node because their placement in a prompt is important. An embedding is basically a "word" with special meaning.
+
+### Negative Embeddings
+
+While most embeddings are put in the prompt, negative ones are placed in a negative prompt to _avoid_ a result. They can be helpful in creating better compositions. Restults can vary by model and the weight of the embedding.

 ## Tips and Philosophy
 
 * ComfyUI has a philosophy of keep it simple. Don't try to create a "do it all" workflow, instead focus on a specific objective.
