+## Running under Windows WSL
+Ollama by default only listens to localhost for connections, so you must set the environment variable OLLAMA_HOST=0.0.0.0:11434
+to make it listen on all interfaces.  
+**Note: this will allow connections to your Ollama server from other devices on any network you are connected to.**  
+If you have Ollama installed via the native Windows installer you must set OLLAMA_HOST=0.0.0.0:11434 in the "System Variable" section
+of the "Environment Variables" control panel.  
+If you installed Ollama under WSL, setting the var with ```export OLLAMA_HOST=0.0.0.0:11434``` before starting the Ollama server will have it listen on all interfaces.
+If your Ollama server is already running, stop and start it to ensure it picks up the new environment variable.  
+You can validate what interfaces the Ollama server is listening on by looking at the server.log file in the Ollama config folder.  
+You should see as one of the first few lines "OLLAMA_HOST:http://0.0.0.0:11434"  
+
+Now that the server is listening on all interfaces you must instruct PAR_LLAMA to use a custom Ollama connection url with the "-u" flag.  
+The command will look something like this:  
+```bash
+parllama -u "http://$(hostname).local:11434"
+```
+
+PAR_LLAMA will remember the -u flag so subsequent runs will not require that you specify it.

+## Contributing
+Start by following the instructions in the section **Installing for dev mode**.  
+
+Please ensure that all pull requests are formatted with black, pass mypy and pylint with 10/10 checks.  
+You can run the make target **do-before-commit** to ensure the pipeline will pass with your changes.  
+There is also a pre-commit config to that will assist with formatting and checks.  
+The easiest way to setup your environment to ensure smooth pull requests is:  
+
+If you don't have pipx installed you can run the following:  
+```bash
+pip install pipx
+```
+
+```bash
+pipx install pre-commit
+pre-commit install
+pre-commit run --all-files
+```
+After running the above all future commits will auto run pre-commit. pre-commit will fix what it can and show what
+if anything remains to be fixed before the commit is allowed.
