You need to include at least three pieces of our lore. It can be anything from where your character lives, where your character visits, what your character have learnt/read about, what kind of creatures they might have known about, what realm they are currently in and if they have been in the previous realm then say it, or what events that might have happened when your character lives and experiences it.

The halfling village is Reedsborough. You can start from there. Maybe you can say "[Insert halfling name here] was born in Reedsborough. His mother told him about Tippen's root (name of a plant), which was a herb usually used for medical treatment." Only in two sentence, I've included two pieces of the lore in LotC. It's up to you to find more of our lore and include it into your biography.
