+You can also run the imageToImage generation via the `Image to image` tab of the app.
+You specify the strength value (0.0 ... 0.9).
+
+The start image is bundled in the app to make the app simple.
+You can replace the image with your favorite one, or add a UI to take an image with a camera or get it from the photo library.

 Download and convert the SD2.1 PyTorch model to CoreML models.
 If you do this on a Mac/8GB memory, please close all running apps except Terminal,
 otherwise the converter will be killed due to memory issues.

 Use these options:
 - `--model-version stabilityai/stable-diffusion-2-base` ... model version
 - `--bundle-resources-for-swift-cli` ... compile and output `mlmodelc` files into `<output-dir>/Resources` folder. The Swift Package uses them.
 - `chunk-unet` ... split the Unet model into two chunks for iOS/iPadOS execution.
 - `--attention-implementation SPLIT_EINSUM` ... use SPLIT_EINSUM for Apple Neural Engine(ANE).
+- `--convert-vae-encoder` ... convert VAEEncode for the imageToImage generation

-How to add Core ML model files to Xcode project:
+Import CoreML model files into Xcode project:
 
 1. In Finder, make the directory, `CoreMLModels`, and put CoreML model files into the directory.
-    - `merges.txt, vacab.json, UnetChunk2.mlmodelc, UnetChunk1.mlmodelc, VAEDecoder.mlmodelc, TextEncoder.mlmodelc`
+    - `merges.txt, vacab.json, UnetChunk2.mlmodelc, UnetChunk1.mlmodelc, VAEDecoder.mlmodelc, VAEEncoder.mlmodelc, TextEncoder.mlmodelc`
     - when you make an app for only Mac, use the Unet.mlmodelc instead of UnetChunk1/2, which are for mobile devices.
-1. Remove the `CoreMLModels` group in the Xcode Project Navigator.
+1. Remove the `CoreMLModels` group in the Xcode Project Navigator if exists.
 1. Drag and drop the `CoreMLModels` directory in Finder into the Xcode Project Navigator, to add the files.
     - At `Choose options for adding these files` dialog, check the `[v] Copy items if needed` and `[v] Create folder references`, and `Add to targets: [v] imggensd2`
