-# Extension
+# New version
 MeDuSA now also supports cell-state deconvolution for annotated `cell states (cell types)`. Please check the link below: 
 https://github.com/LeonSong1995/MeDuSAJ. 
 MeDuSAJ is more robust for estimating cell state (cell type) abundance for rare cell types, albeit with a slightly increased computational burden. Tutorials can be found in the [README](https://github.com/LeonSong1995/MeDuSAJ) of MeDuSAJ.
