Yeah... So like Jacob mentioned, STARs and SIDs are the set routes to approach and depart an airfield.
So this for example, is an expired chart, showing the BRI1A,B,C & E arrival routes to Bristol airport. So for example, following the BRI 1E arrival route, the first VOR is TALGA, to BRECON and then to BRISTOL airport. [ie. arriving from Dublin western parts of Ireland, TALGA is likely the VOR that you'd have already on your route]
I don't know if I'm teaching you to suck eggs, but if this is all new information, then I suggest watching a few YouTube videos to further clarify, there are loads to choose from.
Usually, I use NAVIGRAPH for my approach and departure charts, which are a little clearer on altitude constraints, but for here you can see at AMRAL you must be at 16,000 feet, and AMRAL is 10 nm from RILES.
