 # Installing and running
 The model is natively supported in ComfyUI. The above image contains a workflow; you can open it in ComfyUI or drag-and-drop to get the workflow.
 
+## Generation settings
+- The preview version should be used at about 1MP resolution. E.g. 1024x1024, 896x1152, 1152x896, etc.
+- 30-50 steps, CFG 4-5.
+- A variety of samplers work. Some of my favorites:
+  - er_sde: neutral style, flat colors, sharp lines. I use this as a reasonable default.
+  - euler_a: Softer, thinner lines. Can sometimes tend towards a 2.5D look. CFG can be pushed a bit higher than other samplers without burning the image.
+  - dpmpp_2m_sde_gpu: similar in style to er_sde but can produce more variety and be more "creative". Depending on the prompt it can get too wild sometimes.
+
 # Prompting
 The model is trained on Danbooru-style tags, natural language captions, and combinations of tags and captions.

+## Natural language prompting tips
+- If using pure natural langauge, more descriptive is better. Aim for at least 2 sentences. Extremely short prompts can give unexpected results (this will be better in the final version).
+- You can mix tags and natural language in arbitrary order.
+- You can put quality / artist tags at the beginning of a natural language prompt.
+  - "masterpiece, best quality, @big chungus. An anime girl with medium-length blonde hair is..."
+- Name a character, then describe their basic appearance.
+  - "Digital artwork of Fern from Sousou no Frieren, with long purple hair and purple eyes, wearing a black coat over a white dress with puffy sleeves..."
+  - This is extra important when prompting for multiple characters. If you just list off character names with no description of appearance, the model can get confused.
+
 # Limitations
 - The model doesn't do realism well. This is intended. It is an anime / illustration / art focused model.
 - The model may generate undesired content, especially if the prompt is short or lacking details.
