@@ -8,7 +8,7 @@ Here's a summary of the things in MirageOS 3 that we're most excited about:
 
 MirageOS 3.0 is the first release that integrates the solo5 targets, `virtio` and `ukvm`, fully with the `mirage` front-end tool.  Now you can `mirage configure -t ukvm`, build a unikernel, and run directly with the generated `ukvm-bin`!  We've updated the "hello world" tutorial to reflect our excitement about `ukvm` -- the `ukvm` target is considerably easier to interface with and configure than `xen` was, and for a lot of users this will be a clearer path toward operational deployment of unikernels.
