-Install [dotenv-vault](https://www.dotenv.org/install/).
+Install dotenv-vault.
+
+```shell
+$ brew install dotenv-vault 
+```
+(see [dotenv.org/install](https://www.dotenv.org/install) for other install options)
 
-Encrypt your environment variables.
+Build your encrypted `.env.vault` file from your local .env file.
 
 ```shell
-$ npx dotenv-vault local build
+$ dotenv-vault local build
+```
+
+This creates two files:
+
+* `.env.vault` - containing an encrypted version of your .env file
+* `.env.keys` - containing the decryption key
+
+Boot your application using the encrypted `.env.vault` file instead of your `.env` file.
+
+```
+$ DOTENV_KEY=<key string from .env.keys> npm start
 ```
 
-This will create an encrypted `.env.vault` file along with a `.env.keys` file containing the encryption keys. Set the `DOTENV_KEY` environment variable by copying and pasting the key value from the `.env.keys` file onto your server or cloud provider. For example in heroku:
+If it worked, you'll see the message:
+
+```shell
+[dotenv@16.1.0][INFO] Loading env from encrypted .env.vault
+```
+
+(This [blog post](https://dotenv.org) goes into a full Hello World example.)
+
+Great, now set the `DOTENV_KEY` on your server. For example in heroku:
 
 ```shell
 $ heroku config:set DOTENV_KEY=<key string from .env.keys>
 ```
 
-Commit your .env.vault file safely to code and deploy. Your .env.vault fill be decrypted on boot, its environment variables injected, and your app work as expected.
