How to Use I2I?

Thank you guys for your work!I'm new to comfyui and I'm wondering how to use mistoline in i2i, in the traditional process one can build a latent in the form of an image + vae encoder instead of an empty latent passed into the K-sampler to form a graph generated graph, but I'm not sure how to do it in mistoline.Can anyone give any help on this?Much appreciated!
