+# Send To Negative
+
+## Purpose
+
+This extension allows the use of negative weights in the prompt and moves them to the negative prompt. This allows useful tricks when using a wildcard extension since you can add negative parts from the positive prompt. It will process recursive weights (one inside of another), but won't calculate the multiplied weights.
+
+The extension must be loaded after the wildcard extension. With the "Dynamic Prompts" extension this happens by default due to both extensions default folder names.
