 If you need multiline variables, for example private keys, you can double quote strings and use the `\n` character for newlines:

-PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----\nHkVN9…\n-----END DSA PRIVATE KEY-----\n"
+PRIVATE_KEY="-----BEGIN RSA PRIVATE KEY-----\nHkVN9...\n-----END DSA PRIVATE KEY-----\n"
 ```
