 ## Running the examples as developer
 If you have git installed, check out this repo because it makes it easier to understand the code:
+
 ```bash
 mkdir repos
 cd repos
 git clone https://github.com/OpenSourceAWE/VortexStepMethod.jl
 cd VortexStepMethod.jl/bin
 ./install
 ```
+
 You can launch Julia with:
+
 ```bash
 jl
 ```
+
 or with:
+
 ```bash
 ./bin/run_julia
 ```
+
 Then you can display a menu with the available examples using the GLMakie library:
+
 ```julia
 menu()
 ```
+
 or using the ControlPlots library (faster time-to-first-plot):
+
 ```julia
 menu_cp()
 ```

 It is possible to import the wing geometry using an `.obj` file as shown in the example `ram_air_kite.jl`. During the import the polars are calculated automatically using XFoil. This approach is valid for rigid wings and ram-air kites, but not for leading edge inflatable kites.
 
 Surfplan files can be converted to an input for `VortexStepMethod.jl` using the [SurfplanAdapter](https://github.com/jellepoland/SurfplanAdapter).
