 Frequently Asked Questions
@@ -13,6 +13,31 @@ Yes they do.  All the rclone commands (eg `sync`, `copy` etc) will
 work on all the remote storage systems.
 
 
+### Can I copy the config from one machine to another ###
+
+Sure!  Rclone stores all of its config in a single file.  If you want
+to find this file, the simplest way is to run `rclone -h` and look at
+the help for the `--config` flag which will tell you where it is. Eg,
+
+```
+$ rclone -h
+Sync files and directories to and from local and remote object stores - v1.18.
+[snip]
+Options:
+      --bwlimit=0: Bandwidth limit in kBytes/s, or use suffix k|M|G
+      --checkers=8: Number of checkers to run in parallel.
+  -c, --checksum=false: Skip based on checksum & size, not mod-time & size
+      --config="/home/user/.rclone.conf": Config file.
+[snip]
+```
+
+So in this config the config file can be found in
+`/home/user/.rclone.conf`.
+
+Just copy that to the equivalent place in the destination (run `rclone
+-h` above again on the destination machine if not sure).

 ### Can rclone sync directly from drive to s3 ###
 
 Rclone can sync between two remote cloud storage systems just fine.
