+New features are occasionally added to {poppr}, but it can take time for it to
+get to CRAN. If you know that you want the latest version of {poppr}, (which
+will contain bug fixes and new features to be included in future releases), then
+you can use the custom R-Universe repository, which is updated hourly: 
+<https://zkamvar.r-universe.dev/ui#builds>
+
+To install poppr from the R-Universe, you can use the following code:
+
+```R
+universe <- c("https://zkamvar.r-universe.dev", "https://cloud.r-project.org")
+install.packages("poppr", repos = universe)
+```
+
+The universe repository also contain up-to-date versions of {adegenet} and 
+{hierfstat}, which are commonly used in conjunction with {poppr} and are 
+notoriously out of date on CRAN. 
+
+### Unstable/Development versions
+
+All Development versions of {poppr} will be on GitHub, but need to be compiled.
