+Helpful scripts to run after patches to quickly find common patterns that dqxclarity uses.
+
+### find_names.py
+
+Searches for patterns configured for the `npc_monster_pattern` pattern. Writes the previous 49 bytes of the found string to a file to be used when figuring out the pattern.
+
+Usage:
+
+```
+python -m venv venv
+.\venv\Scripts\activate
+pip install -r requirements.txt
+python find_names.py --help
+```
