## Set configuration
The shell module needs to be configured in order for user interface options to become visible. When you have [created an index](🔗), you get an email with an **episerver.find** section that you add to the site's _web.config_. The Optimizely shell module registration and configuration are done automatically when you install using NuGet packages.
Below are the changes made in configuration when installing the packages.
**Registering Search & Navigation module**
**Adding handler for embedded resources**
## Access rights
Access to views in the shell module is restricted to users in one of three groups:
SearchAdmins (Search & Navigation-specific)
The first two groups have Admin view access in Optimizely Content Management System (CMS), and access to shell module views by default. To grant users without administrator access, create the **SearchAdmins **group for the membership and role provider you are using, and add those users to it.
## Supported browsers
The shell module relies heavily on CSS 3, so only modern browsers are supported. See the [system requirements for Optimizely](🔗).
## Added views
When properly configured, the shell module adds the views and subviews described below to the editing interface.
This view shows [Search statistics](🔗) for the top most frequent searches, searches without hits, and searches without relevant hits. Statistics can be displayed for last 24 hours, last week, last month or last year.
[Best Bets](🔗) – Can be site and language-specific or site and language-independent, depending on choices made in the site and language drop-downs (near the top of the view).
