So, when I code, I am usually in Visual Studio and I am used to writing documentation above my functions as follows:

        /*
         * The is SomeFunction that does some action.
         */
        private void SomeFunction(int inSomeValue)
        {
                // write code here
        }

However, it annoys me that this information doesn’t show up in Visual Studio’s Intellisense. So I took time to look up the proper way to make function documentation show up in Intellisense.

It turns out that you can type /// above a function and Visual Studio will automagically populate the markup needed to have your comments show up in intellisense.

        /// <summary>
        ///  The is SomeFunction that does some action.
        /// </summary>
        /// <param name="inSomeValue">Enter an integer as some value here.</param>
        private void SomeFunction(int inSomeValue)
        {
                // write code here
        }

So it seems if you use this syntax, the function documentation will now show up in Visual Studio’s Intellisense.
