 #### 2.1 Save it as an Environment Variable
 
+Create a file called `.env` in the root directory of your app
+and add the following line:
+
+```txt
+export AUTH_API_KEY=2cfxNaWUwJBq1F4nPndoEHZJ5YCCNqXbJ6GaSXj6BPNTjMSc4EV/2cfxNadrhMZk3iaT1L5k6Wt67c9ScbGNPz8BwLH1qvpDNAARQ9J
+```
+
+The run the following command in your terminal:
+```
+source .env
+```
+That will export the environment variable AUTH_API_KEY.
+
 
+Remember to add `.env` to your [`.gitignore`](https://github.com/dwyl/auth_plug/blob/1ebb60938487da7e740a79b2a4639b29f2ba44ac/.gitignore#L52) file.
+e.g:
+```
+echo ".env" >> .gitignore
+```
