+### Use base prompt
+
+You can use a base prompt to apply the prompt to all areas. You can set a base prompt by adding `ADDBASE` at the end. Base prompts can also be combined with common prompts, but the base prompt must be specified first.

 ### Negative prompt
 
 Negative prompts are equally effective across all regions, but it is possible to set region-specific prompts for negative prompts as well. The number of BREAKs must be the same as the number of prompts. If the number of prompts does not match, the negative prompts will be used without being divided into regions.

 ### Optional Parameters
 
 - `save_mask`: In `Prompt` mode, choose whether to output the generated mask along with the image. The default is `False`.
+- `base_ratio`: Used with `ADDBASE`. Sets the ratio of the base prompt; if base ratio is set to 0.2, then resulting images will consist of `20%*BASE_PROMPT + 80%*REGION_PROMPT`
 
 The Pipeline supports `compel` syntax. Input prompts using the `compel` structure will be automatically applied and processed.
