 1. Download the signing key to a new keyring.
 
    ```bash
-   wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor | sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg
+   $ wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor | \
+       sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg
    ```
 
 1. Verify the key's fingerprint.
 
    ```bash
-   gpg --no-default-keyring --keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg --fingerprint
+   $ gpg --no-default-keyring --keyring /usr/share/keyrings/hashicorp-archive-keyring.gpg \
+       --fingerprint
    ```
    The fingerprint must match `E8A0 32E0 94D8 EB4E A189 D270 DA41 8C88 A321 9F7B`. You can also verify the key on [Security at HashiCorp](https://www.hashicorp.com/security) under **Linux Package Checksum Verification**.
 
 1. Add the official HashiCorp repository to your system. The `lsb_release -cs` command finds the distribution release codename for your current system, such as `buster`, `groovy`, or `sid`.
 
    ```bash
-   echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] https://apt.releases.hashicorp.com $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hashicorp.list
+   $ echo "deb [signed-by=/usr/share/keyrings/hashicorp-archive-keyring.gpg] \
+       https://apt.releases.hashicorp.com $(lsb_release -cs) main" | \
+       sudo tee /etc/apt/sources.list.d/hashicorp.list
    ```
 
+1. Download the package information from HashiCorp.
+
+  ```bash
+  $ sudo apt update
+  ```
+
 1. Install Terraform from the new repository.
 
    ```bash
-   sudo apt update
-   sudo apt install terraform
+   $ sudo apt install terraform
    ```
