+### Alternative Installing Source from within R
+Using the `devtools` the package can also be directly installed from within `R`
+```R
+library(devtools)                                       # Load the dectools
+setwd('<path_to_repo>/CVE')                             # Go into package root
+(path <- build(vignettes = FALSE))                      # Create source package
+install.packages(path, repos = NULL, type = "source")   # Install source package
+library(CVE)                                            # Test
+```
 
 ### Windows / macOS
 Installing from source (for any package which contains compiled code, in our case `C`) on Windows and MacOS requires additional tools.
