 ## Interactive microbiome data exploration with iSEEtree
 
+[iSEEtree](https://microbiome.github.io/iSEEtree/) is a shiny app that provides

+As we did before for `tse`, we add alpha and beta diversity metrics also to the
+to the agglomerated experiment `tse_family`, so we will be able to visualize
+these metrics in the app.

 Launching the app is easy. All you need to do is run the command `iSEE` on the
 `TreeSE` object that you want to explore.
