With filters you can overwrite existing content, or extend it if the source contains an array. The source is often specified. Filters exist everywhere within WordPress and also in Helpful. Helpful tries to use as many features of WordPress as possible, so you only need to understand the filters of WordPress to use the filters of Helpful.
More about filters within WordPress, you can read directly in the documentation of WordPress itself.
