# Customization

### <mark style="color:blue;">Customization</mark>

After the first time you run Fooocus, a config file will be generated at `Fooocus\config.txt`. This file can be edited to change the model path or default parameters.

For example, an edited `Fooocus\config.txt` (this file will be generated after the first launch) may look like this:

```
{
    "path_checkpoints": "D:\\Fooocus\\models\\checkpoints",
    "path_loras": "D:\\Fooocus\\models\\loras",
    "path_embeddings": "D:\\Fooocus\\models\\embeddings",
    "path_vae_approx": "D:\\Fooocus\\models\\vae_approx",
    "path_upscale_models": "D:\\Fooocus\\models\\upscale_models",
    "path_inpaint": "D:\\Fooocus\\models\\inpaint",
    "path_controlnet": "D:\\Fooocus\\models\\controlnet",
    "path_clip_vision": "D:\\Fooocus\\models\\clip_vision",
    "path_fooocus_expansion": "D:\\Fooocus\\models\\prompt_expansion\\fooocus_expansion",
    "path_outputs": "D:\\Fooocus\\outputs",
    "default_model": "realisticStockPhoto_v10.safetensors",
    "default_refiner": "",
    "default_loras": [["lora_filename_1.safetensors", 0.5], ["lora_filename_2.safetensors", 0.5]],
    "default_cfg_scale": 3.0,
    "default_sampler": "dpmpp_2m",
    "default_scheduler": "karras",
    "default_negative_prompt": "low quality",
    "default_positive_prompt": "",
    "default_styles": [
        "Fooocus V2",
        "Fooocus Photograph",
        "Fooocus Negative"
    ]
}
```

Many other keys, formats, and examples are in `Fooocus\config_modification_tutorial.txt` (this file will be generated after the first launch).

Consider twice before you really change the config. If you find yourself breaking things, just delete `Fooocus\config.txt`. Fooocus will go back to default.

A safer way is just to try "run\_anime.bat" or "run\_realistic.bat" - they should already be good enough for different tasks.
