The winger has signed a four-year deal with the Light Blues after they agreed an undisclosed fee for him with the Edinburgh outfit.
Despite a hectic 24 hours which saw Templeton score for the Jambos at Liverpool, train on Merseyside this morning then travel by bus to the capital, he hopes to play on Sunday.
Whether the 23-year-old is selected for the side that faces Elgin City remains to be seen as manager Ally McCoist has to weigh up how fresh his latest recruit will be.
Either way, Templeton is eager to get his Gers career underway in earnest and hopes will be high the exciting forward can make a positive impact.
He told RangersTV.tv: “It has been such a long day and we came back up from Liverpool this morning then I was in at Murray Park for quite a while.
“But it’s good to finally get everything done and I’m looking forward to playing for such a massive club.
“I’d heard some things through the papers and stuff like that but it was only really today that I heard from my agent an offer had gone in.
“Once I had come back up the road, I went to meet him and then we came here to talk to Rangers about it.
“It was strange to play at Anfield last night and then speak about coming to Rangers but as soon as the offer was accepted, it was something I wanted to do.
“I wanted to speak with the manager and see how things were. Now I’m really looking forward to getting started.”
Having put pen to paper on a contract that ties him to Rangers until the summer of 2016, Templeton has shown an impressive long-term commitment to the club.
And he is keen to help take the Light Blues back through the divisions and back to the top of Scottish football and taking advice from two of his old Tynecastle colleagues.
Templeton added: “I’ve spoken to some of the boys such as Ian Black and Lee Wallace and they are loving it here.
“Once I had spoken to them, I thought I wanted to be part of this and to help get Rangers back to where they belong. I’m looking forward to being part of that.
“It’s a good challenge for us. I want to help the club succeed and to get back into Europe again as it should be. I’m looking forward to the next four years.”
