## Usage

1. Start the cache server:
    ```sh
    ./SteamCache2 --memory 1G --disk 10G --disk-path tmp/disk
    ```
2. Configure your DNS:
    - If your on Windows and don't want a whole network implementation (THIS)[#windows-hosts-file-override]

### Windows Hosts File Override

1. Open Notepad as Administrator:
    - Click on the Start menu, type `Notepad`, right-click on Notepad, and select `Run as administrator`.

2. Open the Hosts File:
    - In Notepad, go to `File` > `Open`.
    - Navigate to `C:\Windows\System32\drivers\etc`.
    - Select `All Files` from the dropdown menu to see the hosts file.
    - Open the `hosts` file.

3. Add the Override Entry:
    - At the end of the file, add a new line with the IP address of your SteamCache2 server followed by `lancache.steamcontent.com`. For example:
      ```plaintext
      192.168.1.100 lancache.steamcontent.com
      ```
      Replace `192.168.1.100` with the actual IP address of your SteamCache2 server.

4. Save the Hosts File:
    - Save the changes by going to `File` > `Save`.

5. Flush DNS Cache (optional but recommended):
    - Open Command Prompt as Administrator.
    - Run the following command to flush the DNS cache:
      ```sh
      ipconfig /flushdns
      ```

6. Restart
    - Restart Steam or Restart Your PC

This will direct any requests to `lancache.steamcontent.com` to your SteamCache2 server.
