I need help to understand a crochet pattern

Hey, I am a complete beginner at crochet and I know nothing but I recently got a crochet project to make a throw and I have gotten up to “2nd row” and I dont understand what to do next. It says “(1dc, 1ch) in first tr (1dc, 1ch counts as 1tr throughout), 1tr in each tr to end. Last row forms patt for remainder of Throw. Work 4 rows.” And I don’t understand what it means when it says “Last row forms patt for remainder of throw. Work 4 rows.” WHat does it want me to do?
Cheers, Zoë.
Any help would be muchly appreciated!! xx

Welcome to KnittingHelp!
This is the pattern that you’re to repeat on every row of the project
"(1dc, 1ch) in first tr (1dc, 1ch counts as 1tr throughout), 1tr in each tr to end."
So repeat this for the next 4 rows. Then see what the next instruction is. You’ll be repeating row 2 throughout.
Enjoy making this throw.

Thank you so much!!! That helps me so much!!
