-## ✅ Setup Environment
-```sh
-git clone https://github.com/HorizonRobotics/EmbodiedGen.git
-cd EmbodiedGen
-git checkout v0.1.6
-git submodule update --init --recursive --progress
-conda create -n embodiedgen python=3.10.13 -y # recommended to use a new env.
-conda activate embodiedgen
-bash install.sh basic
-```
-
-Please `huggingface-cli login` to ensure that the ckpts can be downloaded automatically afterwards.
-
-## ✅ Starting from Docker
-
-We provide a pre-built Docker image on [Docker Hub](https://hub.docker.com/repository/docker/wangxinjie/embodiedgen) with a configured environment for your convenience. For more details, please refer to [Docker documentation](https://github.com/HorizonRobotics/EmbodiedGen/tree/master/docker).
-
-> **Note:** Model checkpoints are not included in the image, they will be automatically downloaded on first run. You still need to set up the GPT Agent manually.
-
-```sh
-IMAGE=wangxinjie/embodiedgen:env_v0.1.x

-docker exec -it ${CONTAINER} bash
-```
-
-## ✅ Setup GPT Agent
-
-Update the API key in file: `embodied_gen/utils/gpt_config.yaml`.
-
-You can choose between two backends for the GPT agent:
-
-- **`gpt-4o`** (Recommended) – Use this if you have access to **Azure OpenAI**.
-- **`qwen2.5-vl`** – An alternative with free usage via OpenRouter, apply a free key [here](https://openrouter.ai/settings/keys) and update `api_key` in `embodied_gen/utils/gpt_config.yaml` (50 free requests per day)

-# 🏞️ Layout Generation — Interactive 3D Scenes
-
-Layout Generation enables the generation of diverse, physically realistic, and scalable **interactive 3D scenes** directly from natural language task descriptions, while also modeling the robot's pose and relationships with manipulable objects. Target objects are randomly placed within the robot's reachable range, making the scenes readily usable for downstream simulation and reinforcement learning tasks in any mainstream simulator.

-  <img src="../assets/Iscene_demo2.gif" alt="layout4" style="width: 400px; border-radius: 12px; display: block;">
-</div>
-
-!!! note "Model Requirement"
-    The text-to-image model is based on `SD3.5 Medium`. Usage requires agreement to the [model license](https://huggingface.co/stabilityai/stable-diffusion-3.5-medium).
-
----
-
-## Prerequisites — Prepare Background 3D Scenes
-
-Before running `layout-cli`, you need to prepare background 3D scenes.
-You can either **generate your own** using the [`scene3d-cli`](scene_gen.md), or **download pre-generated backgrounds** for convenience.
-
-Each scene takes approximately **30 minutes** to generate. For efficiency, we recommend pre-generating and listing them in `outputs/bg_scenes/scene_list.txt`.
-
-```bash
-# Option 1: Download pre-generated backgrounds (~4 GB)
-hf download xinjjj/scene3d-bg --repo-type dataset --local-dir outputs
-
-# Option 2: Download a larger background set (~14 GB)
-hf download xinjjj..RLv2-BG --repo-type dataset --local-dir outputs
-```
-
-## Generate Interactive Layout Scenes
-
-Use the `layout-cli` to create interactive 3D scenes based on task descriptions. Each layout generation takes approximately 30 minutes.
-
-```sh
-layout-cli \
-  --task_descs "Place the pen in the mug on the desk" \
-               "Put the fruit on the table on the plate" \
-  --bg_list "outputs/bg_scenes/scene_list.txt" \
-  --output_root "outputs/layouts_gen" \
-  --insert_robot
-```
-
-You will get the following results:
-<div align="center" style="display: flex; justify-content: center; align-items: flex-start; gap: 24px; margin: 20px auto; flex-wrap: wrap;">
-  <img src="../assets/Iscene_demo1.gif" alt="Iscene_demo1"
-       style="height: 200px; border-radius: 12px; display: block; width: auto;">
-  <img src="../assets/Iscene_demo2.gif" alt="Iscene_demo2"
-       style="height: 200px; border-radius: 12px; display: block; width: auto;">
-</div>
-
-
-
-### Batch Generation
-
-You can also run multiple tasks via a task list file in the backend.
-
-```sh
-CUDA_VISIBLE_DEVICES=0 nohup layout-cli \
-  --task_descs "apps/assets/example_layout/task_list.txt" \
-  --bg_list "outputs/bg_scenes/scene_list.txt" \
-  --output_root "outputs/layouts_gens" \
-  --insert_robot > layouts_gens.log &
-```
-
-> 💡 Remove `--insert_robot` if you don’t need robot pose consideration in layout generation.
-
-### Layout Randomization
-
-Using `compose_layout.py`, you can **recompose the layout** of the generated interactive 3D scenes.
-
-```sh
-python embodied_gen/scripts/compose_layout.py \
---layout_path "outputs/layouts_gens/task_0000/layout.json" \
---output_dir "outputs/layouts_gens/task_0000/recompose" \
---insert_robot
-```
-
-### Load Interactive 3D Scenes in Simulators
-
-We provide `sim-cli`, that allows users to easily load generated layouts into an interactive 3D simulation using the SAPIEN engine.
-
-```sh
-sim-cli --layout_path "outputs/layouts_gen/task_0000/layout.json" \
---output_dir "outputs/layouts_gen/task_0000/sapien_render" --insert_robot
-```
-
-!!! tip "Recommended Workflow"
-    1. Generate or download background scenes using `scene3d-cli`.
-    2. Create interactive layouts from task descriptions using `layout-cli`.
-    3. Optionally recompose them using `compose_layout.py`.
-    4. Load the final layouts into simulators with `sim-cli`.

-  --prompts "Art studio with easel and canvas" \
-  --output_dir outputs/bg_scenes/ \
-  --seed 0 \
-  --gs3d.max_steps 4000 \
-  --disable_pano_check
-```
-
-The generated results are organized as follows:
-```sh

-├── gs_model.ply
-├── gsplat_cfg.yml
-├── mesh_model.ply
-├── pano_image.png
-├── prompt.txt
-└── video.mp4
-```
-
-- `gs_model.ply` → Generated 3D scene in 3D Gaussian Splat representation.
-- `mesh_model.ply` → Color mesh representation of the generated scene.
-- `gsplat_cfg.yml` → Configuration file for 3DGS training and rendering parameters.
-- `pano_image.png` → Generated panoramic view image.
-- `prompt.txt` → Original scene generation prompt for traceability.
-- `video.mp4` → Preview RGB and depth preview of the generated 3D scene.
-
-!!! note "Usage Notes"
-    - `3D Scene Generation` produces background 3DGS scenes optimized for efficient rendering in simulation environments. We also provide hybrid rendering examples combining background 3DGS with foreground interactive assets, see the [example]()
-    for details.
-    - In Layout Generation, we further demonstrate task-desc-driven interactive 3D scene generation, building complete 3D scenes based on natural language task descriptions. See the [Layout Generation Guide](layout_gen.md).
