-For security reasons, only certain options are allowed. Please refer to [preset.cpp](../common/preset.cpp) for the complete list of permitted options.
-
-Example usage:
-
-Assuming your repository `username/my-model-with-preset` contains a `preset.ini` with the configuration above:
-
-```sh
-llama-cli -hf username/my-model-with-preset
-
-# This is equivalent to:
-llama-cli -hf username/my-model-with-preset \
-  --hf-repo-draft username/my-draft-model-GGUF \
-  --temp 0.5 \
-  --top-k 20 \
-  --top-p 0.95
-```
-
-You can also override preset arguments by specifying them on the command line:
+The preset will be loaded similarly to the `--models-preset` option. Therefore, you can also override certain params via CLI arguments:
 
 ```sh
 # Force temp = 0.1, overriding the preset value
-llama-cli -hf username/my-model-with-preset --temp 0.1
-```
-
-If you want to define multiple preset configurations for one or more GGUF models, you can create a blank HF repo for each preset. Each HF repo should contain a `preset.ini` file that references the actual model(s):
-
-```ini
-hf-repo = user/my-model-main
-hf-repo-draft = user/my-model-draft
-temp = 0.8
-ctx-size = 1024
-; (and other configurations)
+llama-cli -hf username/my-preset --temp 0.1
 ```
