Can you explain to me in a couple of sentences where the Easter Bunny originated from according to this article? 

Here is an article with some information: 
Easter is known as a time to celebrate the end of the Lenten season and the resurrection of Jesus on Easter Sunday. But for young kids especially, Easter also means candy and eggs full of treats from the mystical and magical Easter Bunny. With all the excitement might come endless questions — where does the Easter Bunny come from? Why does he bring us candy and eggs? How old is he? And most importantly, what does a bunny have to do with the religious holiday?

While legend has told us that the Easter Bunny is a long-eared, cotton-tailed creature who hops from house to house to deliver festive baskets, there's more about his history that you might not be familiar with. Before you break out the delicious Easter desserts and begin your annual family egg hunt, take a minute to learn about the Easter Bunny's connection to this special Christian holiday that goes back to pagan traditions. Find out where the character comes from, how a rabbit became associated with Easter eggs and how he came to be such a beloved symbol for kids over the years.
As Christians probably already know, the Bible makes no mention of a mythical hare who delivers eggs to children on the day of Jesus Christ's resurrection. So, why exactly has a rabbit become a prominent part of one of Christianity's most important celebrations of rebirth and renewal? One theory, according to Time, is that the symbol of the rabbit stems from the ancient pagan tradition on which many of our Easter traditions are based — the festival of Eostre, which honored the goddess of fertility and spring. The goddess's animal symbol was a rabbit, which have long traditionally stood for fertility due to their high reproduction rates.
As for how the character of the Easter Bunny made its way to America, History.com reports that it was first introduced in the 1700s by German immigrants to Pennsylvania, who reportedly brought over their tradition of an egg-laying hare named "Osterhase" or "Oschter Haws" from the Old Country. Legend has it, the rabbit would lay colorful eggs as gifts to children who were good, so kids would make nests in which the bunny could leave his eggs and even sometimes set out carrots in case the hare got hungry. Remind you of any other holiday traditions? Eventually, the custom spread across America until it was a widespread Easter tradition. Over time, the fabled bunny's delivery expanded from just eggs to include other treats such as chocolate and toys. Easter baskets have only gotten more and more elaborate over the years, as one trip to the store this year will tell you.
According to the article, the origin of the easter bunny starts with the rabbit symbolism seen in the pagan spring and fertility festival of Eostre, which influenced many Easter traditions. The Easter Bunny was introduced to the United States around the 1700s by German immigrants who spread the legend of a bunny laying colorful eggs for well-behaved children.
