+## What this workshop covers
 
-## What we will do
+In this workshop we focused on the main points in Hadley Wickham's book on package development ([Wickham 2020](https://r-pkgs.org)) and created an example application together. Workshop attendees will get to know a structured workflow, which will aid them in organizing their personal scripts afterwards. Main topics include function definition in R, the R package structure and the typical package development cycle. If time allows, we will also introduce topics like vignettes, unit tests or shipping data with packages.

-## Regarding your application "abstract"
-
-CAA2021 does not have a formal workshop category, unfortunately, so we submitted this workshop as a session of type "other". If you want to participate in this workshop, you have to hand in a "paper". Of course this formal requirement is not relevant for a workshop, so we would like to ask you to instead submit some lines about your personal level of experience with R. Then we can adjust the workshop according to your skill level.
