+Provision installation of [seaweedfs](https://github.com/chrislusf/seaweedfs) a distributed object storage.
+This role installs the components master, volume and filer.
+
 This role was based on the work of egeneralov.seaweedfs
 
+## Inventory
+
+When used in a play targetting group `all` the role will use all nodes and deploy in such a way
+
+* a master server on the first node of the group
+* a volume server on each node
+* a filer server on the first node of the group
+
+You can also define groups `weed_master`, `weed_filer`, to choose where to deploy the server master and filer accordingly.
+In such case, the volume servers will be configured correctly to contact the master server(s).
+
