+# Modular Diffusers
+
+Modular Diffusers is a unified pipeline that simplifies how you work with diffusion models. There are two main advantages of using modular Diffusers:
+
+* Avoid rewriting an entire pipeline from scratch. Reuse existing blocks and only create new blocks for the functionalities you need.
+* Flexibility. Compose pipeline blocks for one workflow and mix and match them for another workflow where a specific block works better.
+
+The example below composes a pipeline with an [IP-Adapter](./loading_adapters#ip-adapter) to enable image prompting.
+
+Create a [`ComponentsManager`] to manage the components (text encoders, UNets, VAE, etc.) in the pipeline. Add the [stabilityai/stable-diffusion-xl-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0) weights with [`add_from_pretrained`], and load the image encoder and feature extractor for the IP-Adapter with [`add`].
+
+> [!TIP]
+> Reduce memory usage by automatically offloading unused components to the CPU and loading them back on the GPU when they're needed.
+
+```py
+import torch
+from transformers import CLIPVisionModelWithProjection, CLIPImageProcessor
+from diffusers import ModularPipeline, StableDiffusionXLAutoPipeline
+from diffusers.pipelines.components_manager import ComponentsManager
+from diffusers.utils import load_image
+
+components = ComponentsManager()
+components.add_from_pretrained("stabilityai/stable-diffusion-xl-base-1.0", torch_dtype=torch.float16)
+
+image_encoder = CLIPVisionModelWithProjection.from_pretrained("h94/IP-Adapter", subfolder="sdxl_models/image_encoder", torch_dtype=torch.float16)
+feature_extractor = CLIPImageProcessor(size=224, crop_size=224)
+
+components.add("image_encoder", image_encoder)
+components.add("feature_extractor", feature_extractor)
+components.enable_auto_cpu_offload(device="cuda:0")
+```
+
+Use [`from_block`] to load the [`StableDiffusionXLAutoPipeline`] block into [`ModularPipeline`], and use [`update_states`] to update it with the components in [`ComponentsManager`].
+
+```py
+auto_pipe = ModularPipeline.from_block(StableDiffusionXLAutoPipeline())
+auto_pipe.update_states(**components.components)
+auto_pipe.update_states(**components.get(["image_encoder", "feature_extractor"]))
+auto_pipe.to("cuda")
+```
+
+Load and set the IP-Adapter weights in the pipeline.
+
+```py
+auto_pipe.load_ip_adapter("h94/IP-Adapter", subfolder="sdxl_models", weight_name="ip-adapter_sdxl.bin")
+auto_pipe.set_ip_adapter_scale(0.6)
+```
+
+[`ModularPipeline`] automatically adapts to your input (text, image, mask image, IP-Adapter, etc.). You don't need to choose a specific pipeline for a task.
+
+```py
+ip_adapter_image = load_image("https://huggingface.co/datasets/YiYiXu/testing-images/resolve/main/style_ziggy/img5.png")
+output = auto_pipe(prompt="An astronaut eating a cake in space", ip_adapter_image=ip_adapter_image, output="images").images[0]
+output
+```
+
+## Pipeline blocks
+
+[`StableDiffusionXLAutoPipeline`] is a preset arrangement of pipeline blocks. It can be broken down into more modular blocks and rearranged.
+
+This example will show you how to recreate the same setup with [`StableDiffusionXLAutoPipeline`] in a more modular way.
