 ## Installation
 
-To install via pip:

+The archived package can be installed via pip by installing the local file:
 
 ```bash
-pip install compound-splitters-nl
+pip install compound-splitters-nl-*.tar.gz
+# or substitute with your file path
 ```
 
 If you want to use the web API, you will need to install additional dependencies:
 
 ```bash
