This document summarizes the steps to validate a form using CodeIgniter: 1. Load the form helper, form validation library, and specify validation rules. 2. Check if form validation runs false - if so, load the form view. 3. If validation runs true, prep the data and load the success view. The key steps are to load necessary helpers and libraries, set validation rules, check if validation fails or succeeds, and load appropriate views to display errors or success.
