 ## cURL Uploads & Bash Alias
 
 If you frequently upload files to HardFiles via the command line, you can streamline the process by setting up a bash alias. This allows you to use a simple command, like `upload`, to push your files to HardFiles using `curl`.
 
 #### Setting Up:
+
 1. **Edit your `.bashrc` file:** Open your `~/.bashrc` file in a text editor. You can use `nano` or `vim` for this purpose:
 ```shell
 nano ~/.bashrc
 ```
+
 2. **Add the `upload` function:** At the end of the `.bashrc` file, append the following function (replace the domain if you are running your own instance):
 ```shell
 upload() {
     curl -F file=@$1 https://hardfiles.org/
 }
 ```
+
 3. Reload your .bashrc file: To make the new function available in your current session, reload your .bashrc:
 ```shell
 source ~/.bashrc
