 To do so, the `weed filer.remote.sync` process needs to know the default remote storage to create the new bucket.
 
 # Usage
-## Mount all existing remote buckets to local
-TBD
+## Mount all existing remote buckets as local buckets
+
+```
+# in "weed shell"
+> remote.mount.buckets -remote=cloud1 -apply
+```
 
 ## Upload local changes in `/buckets`
+This will also create new buckets in the specified remote storage.
 ```
 $ weed filer.remote.sync -createBucketAt=cloud1
 synchronize /buckets, default new bucket creation in cloud1 ...
 ```

+## Cache or uncache
+The basic implementation mechanism is the same as other mounted folders.
+You may need to create a cronjob to run it periodically.
+```
+# in "weed shell"
+
+# cache all pdf files in a bucket
+> remote.cache -dir=/buckets/some-bucket -include=*.pdf
+
+# uncache files in a bucket that is older than 1 hour and larger than 10KB
+> remote.uncache -dir=/buckets/some-b353  -minAge=3600 -minSize=10240
