Tutorial for using snappyHexMesh with a STL file in OpenFOAM

Question

I have created a vehicle and output a STL file. First I want to use snappyHexMesh to convert the STL file to the proper format for OpenFOAM. Then I want to run a few airflow simulations

I am using OpenFOAM's 5.x and my case directory is here: https://github.com/anujgoyal/openfoam

Slide 13 of this presentation: http://openfoamwiki.net/images/f/f0/Final-AndrewJacksonSlidesOFW7.pdf says that 5 requirements are needed:

Geometry data (stl, nas, obj) in constant/triSurface/Simple Car CFD.STL [DONE]
Dictionary file system/snappyHexMeshDict [DONE, don't know if it is correct]
Hexahedral base mesh (decomposed if running in parallel) [?, don't know where to start]
Dictionary file system/decomposeParDict for parallel runs [?, I have a large Xeon system so I would like to use parallel runs]
All system dictionaries (e.g controlDict, fvSchemes, fvSolutions) [?, don't know what the minimal set of parameters are]

I am having some trouble understanding what values should be in the Hexahedral base mesh, controlDict, fvSchemes and fvSolutions - does anyone have any recommendations? or could you point me to some detailed tutorials that they recommend?

have you already seen this, this and this?

Your snappyHexMeshDict is incomplete. Save .stl file name without spaces. I think you should modifiy $FOAM_TUTORIALS/incompressible/simpleFoam/motorBike/ case for this simulation.
