 # Core ML Models Repository
 
-Thanks to Apple engineers, we can now run Stable Diffusion on Apple Silicon using Core ML!<br>
-However its hard to find compatible models and converting models isn't the easiest thing to do.<br>
-By organizing Core ML models in one place, hopefully it will be easier to find them and for everyone to benefit.
+Thanks to Apple engineers, we can now run Stable Diffusion on Apple Silicon using Core ML!\
+However, it is hard to find compatible models, and converting models isn't the easiest thing to do.\

 ## Conversion Flags
 
-The models were converted using the following flags:<br>
-`--convert-vae-decoder --convert-unet --convert-text-encoder --bundle-resources-for-swift-cli --attention-implementation {SPLIT_EINSUM or ORIGINAL}`

 ## `split_einsum` vs `original` Models
 
-Depending on what compute unit you select, you will need to use the correct model version.<br>
-Some model versions may also generate other image sizes and are named as such.
+Depending on what compute unit you select, you will need to use the correct model version:
+- `split_einsum` is compatible with all compute unit
+- `original` is only compatible with CPU & GPU
 
-`split_einsum` version is compatible with all compute unit options including Neural Engine.<br>
-`original` version is only compatible with CPU & GPU option.
+# Contributing
 
-## Contributing
+We encourage you to have at least one model converted (that this community doesn't already have) under your account that you would be able to contribute before joining. This will help us see those who can actually contribute back to the community.\
+We also encourage you to follow [models](#models-name) and [repo](#repo-name) naming schemes accordingly.

+**Attention**: Apple introduced Image-to-image capabilities in the [ml-stable-diffusion 0.2.0 release](https://github.com/apple/ml-stable-diffusion/releases/tag/0.2.0). All the models that do not have a VAE encoder (hence, not will be able to use Image-to-image), will have a `no-i2i` suffix right after the model name.\
+For example: `stable-diffusion-2-1_no-i2i_original`.\
+From now on, only models with a VAE encoder will be accepted.
 
-### Models Name
+[Contact us on Discord if you are interested in helping out](https://discord.gg/x2kartzxGv).
 
-Models have the following naming scheme: original model name, model version (`split-einsum` or `original`), model size (only if different from `512x512`), vae name (only if different from the original vae).<br>
-Each label is separated by an underscore `_`, and all capitalization from the original name are preserved.<br>
+## Models Name
+
+Models have the following naming scheme:
+1. Original model name
+1. Model version (`split-einsum` or `original`)
+1. Model size (only if different from `512x512`)
+1. VAE name (only if different from the original VAE)
+
+Each label is separated by an underscore `_`, and all capitalization from the original name is preserved.\
 For example: `stable-diffusion-2-1_original_512x768_ema-vae`.
 
-### Repo Name
+## Repo Name
 
-Repos are named with the original diffusers Hugging Face repo name prefixed by `coreml-`.<br>
-All capitalization from the original name are preserved.<br>
+Repos are named with the original diffusers Hugging Face / Civitai repo name prefixed by `coreml-`.\
 For example: `coreml-stable-diffusion-2-1`.
