The BotDetect SharePoint CAPTCHA Feature solution is deployed to a SharePoint server using SharePoint Management Shell as a solution package (.wsp) file.

Download the zip with BotDetect.SharePoint2010.wsp file to your SharePoint 2010 server.
Start the SharePoint 2010 Management Shell on your SharePoint 2010 server (Start → All Programs → Microsoft SharePoint 2010 Products → SharePoint 2010 Management Shell)
Type in the following command to add the solution to SharePoint (use the path to the location where you saved the .wsp file in step 1):

Protect Your SharePoint 2010 List with the SP2010 BotDetect Field

After you deploy the BotDetect SharePoint 2010 solution to your web application, the SP2010 BotDetect Field will become available for your SharePoint lists and libraries. Before you are able to use the SP2010 BotDetect Field in your lists and libraries you are required to activate the SharePoint 2010 BotDetect Site Feature in the site collection where you plan to use it.

Activate the SharePoint 2010 BotDetect Site Feature

To activate this feature follow these steps:

Select Site Actions → Site settings in the root site of your site collection
In the Site settings page, under the Site Collection Administration select the Site collection features option
In the Site Collection features page, find and activate the SharePoint 2010 BotDetect Site Feature

Add the SP2010 BotDetect Field to a SharePoint List

Once you have activated the SharePoint 2010 BotDetect Site Feature you can use the SP2010 BotDetect Field in your SharePoint lists.

To add the BotDetect Field you will use the same approach as for adding other SharePoint fields.

Navigate to the list to which you wish to add the BotDetect Field
From the ribbon select the List settings option
In the List settings page, under the Columns section, click Create Column
In the Create Column page simply select SP2010 BotDetect Field and enter a name. It is recommended to uncheck the Add to default view option, since this field is only relevant for Add and Edit forms.

In case that you did not activate SharePoint 2010 BotDetect Site Feature, the BotDetect field will display a warning message on your forms.

In case this happens, please follow the instructions to activate the SharePoint 2010 BotDetect Site Feature.
