 # packages
 
-Most of the R packages of the [tesselle](https://www.tesselle.org/) project are distributed on [CRAN](https://cran.r-project.org/), but some data packages are too large and can only be installed from our universe: [tesselle.r-universe.dev](https://tesselle.r-universe.dev).
-
-If available, CRAN releases must be regarded as the preferred source.
-
-## Download tesselle packages
-
-If you want to install a package, simply use `install.packages()` with the additional repository:
-
-``` r
-## Enable this universe
-options(repos = c(CRAN = 'https://cloud.r-project.org'),
-                  tesselle = 'https://tesselle.r-universe.dev')
-
-## Install some packages
-install.packages("tabula")
-```
-
-## Use the repository
-
-You can use this repository in your R package (always prefer the CRAN release if available). To do so, prepare the `DESCRIPTION` file of your R package:
-
-* List the package under `Suggests:`
-* Add the line `Additional_repositories: https://tesselle.r-universe.dev`
-* Test your package with `R CMD check --as-cran`
+This is the repository for the [packages portal](https://packages.tesselle.org).
