 ### Setting up PyCall
+
 The airfoilprep.py package (wrapped by the AirfoilPrep.jl package) is written in Python 3.8, so make sure that the Python version linked to PyCall.jl is 3.8. After installing PyCall (] add PyCall), you can do this by running the following:
 
-```import Pkg
+``` shell
+import Pkg
 Pkg.add("PyCall")
 ENV["PYTHON"] = "path/to/your/python3"
-Pkg.build("PyCall")```
+Pkg.build("PyCall")
+```
 
 Then close and reopen the Julia REPL, and run:
 
-```import PyCall
-PyCall.pyversion```
+``` shell
+import PyCall
+PyCall.pyversion
+```
 
 which should reveal your Python version:
 
-```v"3.8"```
+``` shell
+v"3.8"
+```
