 Native Rust library for managing control groups under Linux
 
-Right now the crate only support the original, V1 hierarchy, however support
-is planned for the Unified hierarchy.
+Both v1 and v2 of cgroups are supported.
 
 # Examples
 
 ## Create a control group using the builder pattern
 
 ``` rust
-// Acquire a handle for the V1 cgroup hierarchy.
-let hier = ::hierarchies::V1::new();
+
+
+use cgroups_rs::*;
+use cgroups_rs::cgroup_builder::*;
+
+// Acquire a handle for the cgroup hierarchy.
+let hier = cgroups_rs::hierarchies::auto();
 
 // Use the builder pattern (see the documentation to create the control group)
 //
 // This creates a control group named "example" in the V1 hierarchy.

 // other control groups.
 
 // Get a handle to the CPU controller.
