+Add your openAI api key to `.env`
+
+_warning!_ By default wolverine uses GPT-4 and may make many repeated calls to the api.
 
 ## Example Usage
 
 To run with gpt-4 (the default, tested option):
 
-    python wolverine.py buggy_script.py "subtract" 20 3
+    python wolverine.py examples/buggy_script.py "subtract" 20 3
 
 You can also run with other models, but be warned they may not adhere to the edit format as well:
 
     python wolverine.py --model=gpt-3.5-turbo buggy_script.py "subtract" 20 3
 
+If you want to use GPT-3.5 by default instead of GPT-4 uncomment the default model line in `.env`:
+
+    DEFAULT_MODEL=gpt-3.5-turbo
+
+You can also use flag `--confirm=True` which will ask you `yes or no` before making changes to the file. If flag is not used then it will apply the changes to the file
+
+    python wolverine.py buggy_script.py "subtract" 20 3 --confirm=True
+
 ## Future Plans
 
 This is just a quick prototype I threw together in a few hours. There are many possible extensions and contributions are welcome:
 
 - add flags to customize usage, such as asking for user confirmation before running changed code
 - further iterations on the edit format that GPT responds in. Currently it struggles a bit with indentation, but I'm sure that can be improved
-- a suite of example buggy files that we can test prompts on to ensure reliablity and measure improvement
+- a suite of example buggy files that we can test prompts on to ensure reliability and measure improvement
 - multiple files / codebases: send GPT everything that appears in the stacktrace
 - graceful handling of large files - should we just send GPT relevant classes / functions?
 - extension to languages other than python
