-🤗 Diffusers provides pretrained diffusion models across multiple modalities, such as vision and audio, and serves
-as a modular toolbox for inference and training of diffusion models.
-
-More precisely, 🤗 Diffusers offers:
-
-- State-of-the-art diffusion pipelines that can be run in inference with just a couple of lines of code (see [src/diffusers/pipelines](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines)). Check [this overview](https://github.com/huggingface/diffusers/tree/main/src/diffusers/pipelines/README.md#pipelines-summary) to see all supported pipelines and their corresponding official papers.
-- Various noise schedulers that can be used interchangeably for the preferred speed vs. quality trade-off in inference (see [src/diffusers/schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers)).
-- Multiple types of models, such as UNet, can be used as building blocks in an end-to-end diffusion system (see [src/diffusers/models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models)).
-- Training examples to show how to train the most popular diffusion model tasks (see [examples](https://github.com/huggingface/diffusers/tree/main/examples), *e.g.* [unconditional-image-generation](https://github.com/huggingface/diffusers/tree/main/examples/unconditional_image_generation)).
+**Diffusers** 是一个值得首选用于**生成图像、音频甚至 3D 分子结构**的，最先进的预训练扩散模型库。无论您是在寻找简单的推理解决方案，还是想训练自己的扩散模型，**Diffusers** 这一模块化工具箱都能对其提供支持。本库的设计更偏重于**可用而非高性能**、**简明而非简单**以及**易用而非抽象**。
+
+这个库包含三个主要组件：
+
+1.  **最先进的扩散管道 (diffusion pipelines)**：只需几行代码即可进行推理。
+2.  **可交替使用的各种噪声调度器 (noise schedulers)**：用于平衡生成速度和质量。
+3.  **预训练模型 (models)**：可作为构建模块，并与调度程序结合使用，来创建您自己的端到端扩散系统。

 ## **New** Stable Diffusion is now fully compatible with `diffusers`!  
 
 Stable Diffusion is a text-to-image latent diffusion model created by the researchers and engineers from [CompVis](https://github.com/CompVis), [Stability AI](https://stability.ai/) and [LAION](https://laion.ai/). It's trained on 512x512 images from a subset of the [LAION-5B](https://laion.ai/blog/laion-5b/) database. This model uses a frozen CLIP ViT-L/14 text encoder to condition the model on text prompts. With its 860M UNet and 123M text encoder, the model is relatively lightweight and runs on a GPU with at least 10GB VRAM.

-## Philosophy
-
-- Readability and clarity is preferred over highly optimized code. A strong importance is put on providing readable, intuitive and elementary code design. *E.g.*, the provided [schedulers](https://github.com/huggingface/diffusers/tree/main/src/diffusers/schedulers) are separated from the provided [models](https://github.com/huggingface/diffusers/tree/main/src/diffusers/models) and provide well-commented code that can be read alongside the original paper.
-- Diffusers is **modality independent** and focuses on providing pretrained models and tools to build systems that generate **continuous outputs**, *e.g.* vision and audio.
-- Diffusion models and schedulers are provided as concise, elementary building blocks. In contrast, diffusion pipelines are a collection of end-to-end diffusion systems that can be used out-of-the-box, should stay as close as possible to their original implementation and can include components of another library, such as text-encoders. Examples for diffusion pipelines are [Glide](https://github.com/openai/glide-text2im) and [Latent Diffusion](https://github.com/CompVis/latent-diffusion).
-
-## In the works
-
-For the first release, 🤗 Diffusers focuses on text-to-image diffusion techniques. However, diffusers can be used for much more than that! Over the upcoming releases, we'll be focusing on:
-
-- Diffusers for audio
-- Diffusers for reinforcement learning (initial work happening in https://github.com/huggingface/diffusers/pull/105).
-- Diffusers for video generation
-- Diffusers for molecule generation (initial work happening in https://github.com/huggingface/diffusers/pull/54)
-
-A few pipeline components are already being worked on, namely:
-
-- BDDMPipeline for spectrogram-to-sound vocoding
-- GLIDEPipeline to support OpenAI's GLIDE model
-- Grad-TTS for text to audio generation / conditional audio generation
-
-We want diffusers to be a toolbox useful for diffusers models in general; if you find yourself limited in any way by the current API, or would like to see additional models, schedulers, or techniques, please open a [GitHub issue](https://github.com/huggingface/diffusers/issues) mentioning what you would like to see.
