# Modifying Gutenberg Editor

 * Perhaps I’m looking in the wrong places but I can’t find any documentation on
   this: Since Gutenberg is JS-based, it appears that hooks and filters that could
   previously be used to modify the editor layout will no longer work. For example,
   if I want to change the default “Add title” text in the title block or add a 
   custom element to the sidebar. Especially for custom post types… Does all that
   have to be done using JS now? Is it even possible? Is there any documentation
   explaining how to go about doing that? Is there some kind of functions.js file
   that we will need to add to themes and plugins for functionality that used to
   go in functions.php?
 * Trying to future proof my current projects, thanks for the help. I hate to be
   a pessimist but this roll-out seems primed to be a giant mess and I’d like to
   avoid as many sleepless nights fixing broken websites as possible. Surely there’s
   at least some kind of documentation in the works that I could look at?

 * So much came to ask this. Shame it hasn’t been answered.

 * A lot of stuff will be backwards compatible, not sure about hooks and filters,
   but this link has a tutorial on blocks.

 * Hiya,
 * Sorry this hasn’t been answered yet, the link from Joz is a great starting point
   though!
 * So moing forward, it is beneficial to make meta content in JS if you want to 
   really take advantage of Gutenberg, but existing meta boxes will be imported 
   under `Extended settings` in the sidebar for backwards compatibility.
 * As for hooks and filters, some may go away with Gutenberg, but we’re working 
   on getting hooks and filters for JS as well in core, to really give you some 
   flexibility (and not only in relation to Gutenberg).

 * The editor text is too small for most of our staff and with the classic editor
   i had to make it larger. How to do that with Gutenberg?

 * You can enqueue styles to override Gutenberg defaults, just like you would enqueue
   them in plugins or themes. [https://wordpress.org/gutenberg/handbook/blocks/applying-styles-with-stylesheets/](https://wordpress.org/gutenberg/handbook/blocks/applying-styles-with-stylesheets/)
   has some information on how to do this, although it’s part of a block-tutorial
   the steps covered there are the same and do apply to the whole admin area.
 * I’d like to point out that this topic is more than 3 months old, as such I’ll
   be closing it after this reply. This is because Gutenberg development is moving
   rapidly, and scenarios from 3 months ago are unlikely to be the same today.
