### Manually

To manually install the nodes, you may alternatively do the following:

1. Download an archive of the nodes by cliking the "Download Latest" button at <https://registry.comfy.org/publishers/finegrain/nodes/comfyui-refiners>, or by running the following command:
```shell
curl -o comfyui-refiners.zip https://storage.googleapis.com/comfy-registry/finegrain/comfyui-refiners/1.0.4/node.tar.gz
```

2. Extract the archive to the `custom_nodes` directory:
```shell
unzip -d custom_nodes/comfyui-refiners comfyui-refiners.zip
```

3. Install the nodes' dependencies:
```shell
pip install -r custom_nodes/comfyui-refiners/requirements.txt
```

4. Remove the (now useless) downloaded archive:
```shell
rm comfyui-refiners.zip
```
