Welcome back
In Revolution there is something called the Package Manager. You can find it under System in the top menu of the manager.
From there, click on Download Extras, choose to select a provider, choose modxcms.com, and browse through the repository to find the addons you need.
Next, click the download button and it will be added to your workspace where you can simply click install and follow the on screen instructions to get your extras added.
The basic addons are:
- building menus: Wayfinder
- fetching resource stuff (like the old Ditto, Reflect etc): getResources
- comments (former Jot): Quip
The other addons depend on what you’re using the site for, but especially the first two are used on pretty much all sites.
You may also want to install TinyMCE if you are used to RTE editors for resources, and if you like CodeMirror for syntax highlighting and line numbers in chunks/snippets/plugins. All from the package manager.
