HP laptop 15-efxxx, windows 10 home

Hi, I just acquired this HP laptop 15-efxxx and would like to upgrade the internal memory. what options do I have available as It runs on Widows 10 home edition and it has 4 GB RAM and a 238 GB storage. I would like to bump them both up possibly to 1 TB storage and 8GB Ram. Please help me identify what parts I would need and it can be done at all or would I have to make more modifications? Thanks for your help.
