 #### Example:
 Running on all interfaces, port 8080, storing data in /opt/data
 ```
-$ ./pict-rs -a 0.0.0.0:8080 -p /opt/data
+$ ./pict-rs -a 0.0.0.0:8080 -p /opt/data run
 ```
 Running locally, port 9000, storing data in data/, and converting all uploads to PNG
 ```
-$ ./pict-rs -a 127.0.0.1:9000 -p data/ -f png
+$ ./pict-rs -a 127.0.0.1:9000 -p data/ -f png run
 ```
 Running locally, port 8080, storing data in data/, and only allowing the `thumbnail` and `identity` filters
 ```
-$ ./pict-rs -a 127.0.0.1:8080 -p data/ -w thumbnail identity
+$ ./pict-rs -a 127.0.0.1:8080 -p data/ -w thumbnail identity run
 ```
 Running from a configuration file
 ```
-$ ./pict-rs -c ./pict-rs.toml
+$ ./pict-rs -c ./pict-rs.toml run
 ```
-Migrating between storage backends
+Migrating to object storage from filesystem storage (both storages must be configured in pict-rs.toml)
 ```
-$ ./pict-rs -p ./data --migrate-file ./migrate.toml
+$ ./pict-rs -c ./pict-rs.toml --store filesystem migrate-store object-storage
+```
+Dumping commandline flags to a toml file
+```
+$ ./pict-rs -p data/ --store object-storage --object-storage-bucket-name pict-rs --object-storage-region us-east-1 dump pict-rs.toml
