 # String Essentials - Custom nodes for ComfyUI
 
-Easy to use string manipulation nodes for ComfyUI (strip/remove multiple text strings or search and replace text strings). Particularly useful for modifying text from LLM outputs (Ollama, Claude.ai, OpenAI ChatGPT), such as prompts or image-to-text description results. Nodes will be located under standard `Add Node` > `utils` menu. 
+Simple string manipulation nodes for ComfyUI (strip/remove text strings, search and replace text strings, preview modified string outputs). Particularly useful for modifying text from LLM outputs (Ollama, Claude.ai, OpenAI ChatGPT), such as prompts or image-to-text description results. No bloat/additional Python dependencies or external modules required. Nodes use a small amount of basic Python and Javascript code.

+Replaces text strings with new strings (replace/swap words etc.). Each line should contain a search and replace pair separated by the replacement_delimiter (default is double colon `::`). Example to replace dog with cat `dog::cat`. Supports mulitple string replacements, just add one replacement per line.
