 [standalone SD Prompt Reader](https://github.com/receyuki/stable-diffusion-prompt-reader). 
 It uses the Image Data Reader from the 
 [standalone SD Prompt Reader](https://github.com/receyuki/stable-diffusion-prompt-reader), 
 allowing it to support the same formats and receive updates along with the

+### Prompt Saver Node
+- The `Prompt Saver` Node and The `Parameter Generator` Node are designed to be used together.  
+- The `Prompt Saver` Node will write additional metadata in the A1111 format to the output images 
 to be compatible with any tools that support the A1111 format, 
 including SD Prompt Reader and Civitai. 
 Due to custom nodes and complex workflows potentially causing issues with SD Prompt Reader's ability 
 to read image metadata correctly, it is recommended to embed this node within the workflow 
 to ensure maximum compatibility.   
-- Since it's not possible to directly extract metadata from KSampler, it is necessary to 
-use the Parameter Generator Node to generate parameters and simultaneously output them to both 
-the Prompt Saver Node and KSampler.
+- Since it's not possible to directly extract metadata from `KSampler`, it is necessary to 
+use the `Parameter Generator` Node to generate parameters and simultaneously output them to both 
+the `Prompt Saver` Node and `KSampler`.

+## Parameter Generator Node
+- Since it's not possible to directly extract metadata from `KSampler`, it is necessary to 
+use the `Parameter Generator` Node to generate parameters and simultaneously output them to both 
+the `Prompt Saver` Node and `KSampler`.
+- The `model_version` and `aspect_ratio` are used only for calculating the optimal resolution of the selected model version 
+under the chosen aspect ratio. The calculation method is based on the 
+[Stability AI development documentation](https://platform.stability.ai/docs/features/api-parameters#about-dimensions) 
+and the [StableSwarmUI source code](https://github.com/Stability-AI/StableSwarmUI) (developed by Stability AI).
+- `refiner_start` refers to the proportion of steps completed when the refiner starts running, 
+i.e., the proportion of base steps to total steps. This is used to calculate the `start_at_step` (`REFINER_START_STEP`)
+required by the refiner `KSampler` under the selected step ratio.

 ### Prompt Merger Node & Type Converter Node
 - Since the A1111 format cannot store `text_g` and `text_l` separately, SDXL users need to use 
-the Prompt Merger Node to combine `text_g` and `text_l` into a single prompt.
-- In some cases, inputs like `model_name`, `sampler_name`, and `scheduler` may conflict with other custom nodes. 
-You can use the SD Type Converter to convert them into `STRING` type and then 
-input them into `model_name_str`, `sampler_name_str`, and `scheduler_str`. Please note that inputs of type `STRING` 
-have higher priority, so do not connect `STRING` inputs unless necessary, as the Prompt Saver will prioritize reading 
-`STRING` inputs over regular ones.

+- Since `model_name`, `sampler_name`, and `scheduler` are special types 
+that cannot be directly used by some other nodes,
+You can use the `Type Converter` Node to convert them into `STRING` type.
