 ## way_function
 
-Given an OpenStreetMap way, the way_function will either return nothing (meaning we are not going to route over this way at all), or it will set up a result hash to be returned. The most important thing it will do is set the value of `result.forward_speed` and `result.backward_speed` as a suitable integer value representing the speed for traversing the way.
+Given an OpenStreetMap way, the `way_function` will either return nothing (meaning we are not going to route over this way at all), or it will set up a result hash to be returned. The most important thing it will do is set the value of `result.forward_speed` and `result.backward_speed` as a suitable integer value representing the speed for traversing the way.
 
 All other calculations stem from that, including the returned timings in driving directions, but also, less directly, it feeds into the actual routing decisions the engine will take (a way with a slow traversal speed, may be less favoured than a way with fast traversal speed, but it depends how long it is, and... what it connects to in the rest of the network graph)
 
-Using the power of the scripting language you wouldn't typically see something as simple as a `result.forward_speed = 20` line within the way_function. Instead a way_function will examine the tagging (e.g. `way:get_value_by_key("highway")` and many others), process this information in various ways, calling other local functions, referencing the global variables and look-up hashes, before arriving at the result.
