title: How to add custom metaboxes to taxonomies?
body: <p>So I know how to save things when a taxonomy is edited like this:</p>
  
  <pre><code>if( !function_exists('mytaxonomysave') ):
  function mytaxonomysave($term_id, $tt_id, $taxonomy) {
     if($taxonomy == 'series'){
         if(isset($_POST['type'])){
             update_term_meta($term_id, 'type', $_POST['type']);
         }
     }
  }
  endif;
  add_action( 'edit_term', 'mytaxonomysave', 10, 3 );
  </code></pre>
  
  <p>But I have no idea how to add a the metabox to the proper areas, what can I do? whats the correct hook¿</p>
