+Each time you run the ESMValTool, it will produce a new output directory within your specified work directory with the name of the recipe and the tagged runtime. This folder should contain four folders:
+- run
+- work
+- preproc
+- plots
 
 > ## Inspect the output:
-> Now that you have run the esmvaltool command for the first time, please locate your output directory.
-> Each time you run ESMValTool, it will produce a new output directory with the following format:

 > If you’re missing the preproc directory, then your config-user.yml file has the value remove_preproc_dir set to true (this is used to save disk space). Please set this value to false and run the recipe again.
