+The library supports building against Stackage LTS-6 and LTS-8. To
 install from Hackage using `stack`:
 
     $ stack install --resolver lts-6.35 sbp # (LTS-6)
 
 or
 
-    $ stack install --resolver lts-8.21 sbp # (LTS-8)
-
-or
-
-    $ stack install --resolver lts-5.18 sbp # (LTS-5)
+    $ stack install --resolver lts-8.22 sbp # (LTS-8)
 
 Note that we explicitly specify the resolvers to use, as installing `libsbp` may
 fail to build with more recent resolvers.
