-Standalone Baremetal Service with Ironic
+Nimble aims to separate bare metal computing management from Nova, which
+is designed specifically for BMs, so we can provide a more lightweight and
+convenient platform with more advanced features by leveraging Ironic. Besides
+this, we also plan to support RSD(Rack Scale Design), so we can not only
+provide Pre-set Configuration Servers but also Custom Servers.
 
-Please fill here a long description which must be at least 3 lines wrapped on
-80 cols, so that distribution package maintainers can use it in their packages.
-Note that this is a hard requirement.
