 ```bash
-uvx --from git+https://github.com/alDuncanson/Handler.git@v0.1.2 handler
+uvx --from git+https://github.com/alDuncanson/Handler.git@v0.1.3 handler
 ```
 
 or, install it globally:
 
 ```bash
-uv tool install git+https://github.com/alDuncanson/Handler.git@v0.1.2
+uv tool install git+https://github.com/alDuncanson/Handler.git@v0.1.3
