 # Swift
 
-Swift is not installed by default, you can enable easily by adding this to your `localrc`:
+Swift is enabled by default configured with only one replica to avoid being IO/memory intensive on a small vm. When running with only one replica the account, container and object services will run directly in screen. The others services like replicator, updaters or auditor runs in background.
 
-    enable_service swift
+If you would like to disable Swift you can add this to your `localrc` :
+
+    disable_service s-proxy s-object s-container s-account
 
 If you want a minimal Swift install with only Swift and Keystone you can have this instead in your `localrc`:
 
     disable_all_services
-    enable_service key mysql swift
+    enable_service key mysql s-proxy s-object s-container s-account
+
+If you only want to do some testing of a real normal swift cluster with multiple replicas you can do so by customizing the variable `SWIFT_REPLICAS` in your `localrc` (usually to 3).
 
-If you use Swift with Keystone, Swift will authenticate against it. You will need to make sure to use the Keystone URL to auth against.
+# Swift S3
 
 If you are enabling `swift3` in `ENABLED_SERVICES` devstack will install the swift3 middleware emulation. Swift will be configured to act as a S3 endpoint for Keystone so effectively replacing the `nova-objectstore`.
 
 Only Swift proxy server is launched in the screen session all other services are started in background and managed by `swift-init` tool.
-
-By default Swift will configure 3 replicas (and one spare) which could be IO intensive on a small vm, if you only want to do some quick testing of the API you can choose to only have one replica by customizing the variable `SWIFT_REPLICAS` in your `localrc`.
