In this section we are going to look at Helm's tool for providing instructions to your chart users. At the end of a `helm install` or `helm upgrade`, Helm can print out a block of helpful information for users. This information is highly customizable using templates.
To add installation notes to your chart, simply create a `templates/NOTES.txt` file. This file is plain text, but it is processed like as a template, and has all the normal template functions and objects available.
Using `NOTES.txt` this way is a great way to give your users detailed information about how to use their newly installed chart. Creating a `NOTES.txt` file is strongly recommended, though it is not required.
