 ### Epiverse-TRACE R packages
 
 Our strategy is to gradually incorporate specialised **R packages** into a traditional analysis pipeline. These packages should fill the gaps in these epidemiology-specific tasks in response to outbreaks.
 
 ![In **R**, the fundamental unit of shareable code is the **package**. A package bundles together code, data, documentation, and tests and is easy to share with others ([Wickham and Bryan, 2023](https://r-pkgs.org/introduction.html))](episodes/fig/pkgs-hexlogos-2.png).

+### 3. Setup an RStudio project and folder
+
+We suggest to use RStudio Projects. 
+
+::::::::::::::::::::::::::::::::: checklist
+
+#### Follow these steps
+
+- **Create an RStudio Project**. If needed, follow this [how-to guide on "Hello RStudio Projects"](https://docs.posit.co/ide/user/ide/get-started/#hello-rstudio-projects) to create a New Project in a New Directory.
+- **Create** the `data/` folder inside the RStudio project or corresponding directory. Use the `data/` folder to **save** the data sets to download.
+
+The directory of an RStudio Project named, for example `workshop`, should look like this:
+
+```
+workshop/
+|__ data/
+|__ workshop.Rproj
+```
