-        Note that by default this will not start any services that the
-        command's service links to. So if, for example, your one-off command
-        talks to your database, you will need to either run `fig up -d db`
-        first, or use `fig run --up SERVICE COMMAND [ARGS...]`.
+        By default, linked services will be started, unless they are already
+        running. If you do not want to start linked services, use
+        `fig run --no-links SERVICE COMMAND [ARGS...]`.
 
         Usage: run [options] SERVICE COMMAND [ARGS...]

-            -d    Detached mode: Run container in the background, print new

-            -T    Disable pseudo-tty allocation. By default `fig run`
-                  allocates a TTY.
-            --rm  Remove container after run. Ignored in detached mode.
-            --up  Also start services that the command's service links to
+            -d          Detached mode: Run container in the background, print

+            --rm        Remove container after run. Ignored in detached mode.
