Use a miter saw or miter box to cut the end of each board at an angle then secure the boards to the back of the gate using wood screws.
Install and trim the posts according to your plan.
Once removed rid the boards of any nails.

How to build a picket fence.
2 mark stringer positions.
Use a line level a water level or a regular level and a helper to make sure your string line is level.
Use a post level to ensure the post is plumb and pour concrete to hold the post in place.
Set the posts in concrete and space them as desired but no more than 96 on center.
If you re building a traditional picket fence you can use pre made picket fence panels or you can attach pickets to horizontal rails.
It is not necessary to fill the hole with concrete all the way to the top.
To strengthen the gate and add a touch of charm remove two pickets from the scrap end of the fence panel.
In this project the pickets stand at 36 above grade and the posts are 38 without the post caps.
