The learnr package in R allows for the creation of interactive tutorials that can include markdown formatted text, R code examples, exercises, and quizzes. This format is particularly suited for R courses as it engages learners with hands-on practice and immediate feedback all in a single document. \n",
+    "For R courses, we recommend using **learnr** tutorials where appropriate. The learnr package in R enables the development of interactive tutorials that incorporate markdown-formatted text, R code examples, exercises, and quizzes. This format is especially well-suited to R instruction, as it offers learners hands-on practice with immediate feedback within a single, cohesive document. However, if the course content is better served by an alternative format, instructors are encouraged to use their professional judgment in selecting the most effective approach.\n",

     "These tutorials are distrbuted as an R package [cfrr-r-tutorials](https://github.com/coding-for-reproducible-research/cfrr-r-tutorials) and should be developed in that repo. A homepage, with details on the course and instructions for how to launch the tutorial should be included in this repo. \n",
