+
+Anime image generation + LoRA training setup.
+
+## Stack
+
+- **ComfyUI** — image generation UI
+- **NoobAI-XL** — base anime model (SDXL-based, SFW+NSFW)
+- **kohya_ss** — LoRA training
+
+## Requirements
+
+- Python 3.10+ installed and in PATH
+- Git installed
+- NVIDIA GPU with CUDA (4070 recommended)
+- ~20GB free disk space for models
+
+## Setup
+
+Run once to install everything:
+
+```powershell
+.\setup.ps1
+```
+
+This will:
+1. Clone ComfyUI and install dependencies
+2. Clone kohya_ss and install dependencies
+3. Install ComfyUI custom nodes (AnimateDiff, ControlNet, etc.)
+4. Download the NoobAI-XL base model + VAE
+
+## Launch
+
+```powershell
+# Start image generation UI (opens browser at localhost:8188)
+.\launch_comfyui.ps1
+
+# Start LoRA training UI (opens browser at localhost:7860)
+.\launch_kohya.ps1
+```
+
+## LoRA Training
+
+1. Put your training images in `training_data/<your_lora_name>/img/10_<trigger_word>/`
+2. Copy `training/example_lora_config.toml` and edit it
+3. Launch kohya and use the GUI, or run `.\train_lora.ps1 <config_file>`
+

+## Model Downloads
+
+Base model (NoobAI-XL Vpred):
+- https://civitai.com/models/833294
+
+Good NSFW VAE:
+- Already baked into NoobAI, but sdxl_vae.safetensors from stabilityai works too
