Additional setup:

Make brackets more visible

$ cd ~/.atom/
$ cp styles.less styles.less.bkp


File styles.less I replace on:

$ vi styles.less


editor, atom-text-editor::shadow {

    .bracket-matcher {
        border-bottom: 1px solid lime;
        position: absolute;
        border: 1px solid rgba(0, 255, 0, 0.7);
        background-color: rgba(0, 255, 0, 0.3);
        border-radius: 32px
    }
}
