+
+Remote resources can be used for a lot of things, including config files and scripts.
+
+## Config file
+
+For the main config file to be fetched remotely, pass the URL using `-f [url]`.
+
+If using S3, you should use the s3 protocol URI: `s3://bucketName/key/path`. You will also need to set the env variable `S3_ENDPOINT` to the appropriate value. The flag `--s3-endpoint` can be used to override this value or to set this value, if not already set.

+## Scripts

+Scripts will be coming later.
