I did the following but I can't complete step 5. How do I locate and change the web.config they are saying to? 

This is an install instruction for the effority.MenuNavigationProvider. 
It replaces DNNMenuNavigationProvider and provides the same features plus multi language capabilities.


To use it in your DotNetNuke Installation, please follow these steps:


1. Make sure that the Effority Ealo Core API (DNN Module) is installed. (Can be downloaded at http://ealo.codeplex.com)


2. Make sure that the Effority Tab Localization Module is installed.  (Can be downloaded at http://ealo.codeplex.com)


3. Add the following tag to the navigation provider section in your web.config


<add name="EfforityMenuNavigationProvider" type="effority.MenuNavigationProvider, effority.MenuNavigationProvider" providerPath="~\Providers\NavigationProviders\effority.MenuNavigationProvider\"/>


sample:


<configuration>
...
<dotnetnuke>
...
     <navigationControl defaultProvider="SolpartMenuNavigationProvider">
       <providers>
         <clear />
         <add name="DNNDropDownNavigationProvider" type="DotNetNuke.NavigationControl.DNNDropDownNavigationProvider, DotNetNuke.DNNDropDownNavigationProvider" providerPath="~\Providers\NavigationProviders\DNNDropDownNavigationProvider\" />
         <add name="ASP2MenuNavigationProvider" type="DotNetNuke.NavigationControl.ASP2MenuNavigationProvider, DotNetNuke.ASP2MenuNavigationProvider" providerPath="~\Providers\NavigationProviders\ASP2MenuNavigationProvider\" />
         <add name="DNNMenuNavigationProvider" type="DotNetNuke.NavigationControl.DNNMenuNavigationProvider, DotNetNuke.DNNMenuNavigationProvider" providerPath="~\Providers\NavigationProviders\DNNMenuNavigationProvider\" />
         <add name="DNNTreeNavigationProvider" type="DotNetNuke.NavigationControl.DNNTreeNavigationProvider, DotNetNuke.DNNTreeNavigationProvider" providerPath="~\Providers\NavigationProviders\DNNTreeNavigationProvider\" />
         <add name="SolpartMenuNavigationProvider" type="DotNetNuke.NavigationControl.SolpartMenuNavigationProvider, DotNetNuke.SolpartMenuNavigationProvider" providerPath="~\Providers\NavigationProviders\SolpartMenuNavigationProvider\" />
<!-- add this line -->         <add name="EfforityMenuNavigationProvider" type="effority.MenuNavigationProvider, effority.MenuNavigationProvider" providerPath="~\Providers\NavigationProviders\effority.MenuNavigationProvider\"/>
       </providers>
     </navigationControl>
     ...
</dotnetnuke>
</configuration>




5. Change the value of the Attribute ProviderName of the <dnn:NAV ... /> tag in your skin to EfforityMenuNavigationProvider
