-## Prequisites
+## Running the simulation
+
+1. Clone or unzip the repository, e.g,
 
-R packages needed for running the simulations can be found on file `renv.lock`.
-Notice that the package *extreme* can be only installed from the corresponding
-Github repository with
 ```
-devtools::install_github("perej1/extreme")
+git clone https://github.com/perej1/extreme.git
 ```
 
-## Running the simulation
+2. Install required packages by navigating to the project's root, and then, by
+   running the following R command
+
+```
+# install.packages("renv")
+renv::restore()
+```
+3. Lastly, run simulations with
 
-Run the following on bash command line
 ```
 bash plot-batch.sh
 ```
