Does this girl like me?

Today I finally asked this girl for her phone number. I asked her if she wanted to hang out, then i asked for her number. She said that would be cool and then she gave me her num. I asked if she wanted mine and she said just text me and then ill have it. Is that a good sign? And she never said she had a bf. Does it sound like she likes me and she also looks and smiles at me a lot in cl.
