<human>:  I need help understanding what a 401(k) savings plan is and how I can set one up.
<bot>: A 401(k) savings plan is a type of retirement savings plan offered by many employers. It allows you to set aside a portion of your pay into a retirement savings account, typically with investment options including stocks, bonds, and mutual funds. To set up a 401(k) plan, contact an employer who offers the plan and speak to the human resources department. They can tell you more information about the plan and how to enroll.
