How do I comment a publicly visible type Enum?

Like this:

/// <summary>
/// Conditional statements
/// </summary>
public enum ConditionType
{
    ///<summary>A == B</summary>
    Equal,
    ///<summary>A != B</summary>
    NotEqual,
    ///<summary>A > B</summary>
    GreaterThan,
    ///<summary>A >= B</summary>
    GreaterThanOrEqual,
    ///<summary>A < B</summary>
    LessThan,
    ///<summary>A <= B</summary>
    LessThanOrEqual
}

(Yes, this can get very tedious)

You may want to use different texts in the comments.

By the way. your enum should actually be called ComparisonType.
