 3. ### Install `ollama`
+
+    Ollama, a Docker-based wrapper of `llama.cpp`, serves the inference engine and enables inference from the language models you will download. It'll be installed as a service, so it runs automatically at boot.

     - Download `ollama` from the official repository:
         ```
         curl -fsSL https://ollama.com/install.sh | sh
         ```
-    - (Recommended) We want our API endpoint to be reachable by the rest of the LAN. For `ollama`, this means setting `OLLAMA_HOST=0.0.0.0` in the `ollama.service`. 
-      - Run the following command to edit the service:

 - Disable Secure Boot in the BIOS if you're having trouble with the Nvidia drivers not working. For me, all packages were at the latest versions and `nvidia-detect` was able to find my GPU correctly, but `nvidia-smi` kept returning the `NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver` error. [Disabling Secure Boot](https://askubuntu.com/a/927470) fixed this for me. Better practice than disabling Secure Boot is to sign the Nvidia drivers yourself but I didn't want to go through that process for a non-critical server that can afford to have Secure Boot disabled.
 
 ### Ollama
+- If you receive the `could not connect to ollama app, is it running?` error, your `ollama` instance wasn't served properly. This could be because of a manual installation or the desire to use it at-will and not as a service. To run the `ollama` server once, run:
+    ```
+    ollama serve
+    ```
+    Then, **in a new terminal**, you should be able to access your models regularly by running:
+    ```
+    ollama run (model)
+    ```
+    For detailed instructions on _manually_ configuring `ollama` to run as a service (to run automatically at boot), read the official documentation [here](https://github.com/ollama/ollama/blob/main/docs/linux.md). You shouldn't need to do this unless your system faces restrictions using Ollama's automated installer.

 - If you receive the `Failed to open "/etc/systemd/system/ollama.service.d/.#override.confb927ee3c846beff8": Permission denied` error from Ollama after running `systemctl edit ollama.service`, simply creating the file works to eliminate it. Use the following steps to edit the file.
