 Find the latest version of Restic on their [GitHub releases page](https://github.com/restic/restic/releases/latest). Since I'm assuming this is a Linux server, we only want the file ending in `_linux_amd64.bz2`. (For a 32-bit Linux server, find `_linux_386.bz2`. Windows, macOS, and BSD binaries are also there.) Right-click and copy the direct URL for that file and head over to your server's command line to download it into your home directory:
 
-```bash
+```bash {linenos=false}
 cd ~
 wget https://github.com/restic/restic/releases/download/v0.9.5/restic_0.9.5_linux_amd64.bz2
 ```
 
 Next, we'll unzip the download in place:
 
-```bash
+```bash {linenos=false}
 bunzip2 restic_*
 ```
 
 This should leave us with a single file: the Restic binary. In order to make Restic available system-wide and accessible with a simple `restic` command, we need to move it into the `/usr/local/bin` folder, which requires `sudo` access:
 
-```bash
+```bash {linenos=false}
 sudo mv restic_* /usr/local/bin/restic
 sudo chmod a+x /usr/local/bin/restic
 ```
 
 Now's a good time to run `restic` to make sure we're good to move on. If you see the version number we downloaded, you're all set!

 We need to store these keys as environment variables named `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`. For now, we'll set these temporarily until we automate everything in the next step.

 We'll also need to tell Restic where the bucket is located and set a secure password to encrypt the backups. You can generate a super-secure 32-character password by running `openssl rand -base64 32` — just make sure you store it somewhere safe!
