-## Creating Banner Ad Objects
+## Banner Ad Objects
+
+Mediation SDK 4.6.0 introduces a new [Adaptive Banner](https://docs.chartboost.com/en/mediation/ad-types/#adaptive-banner/) ad format, capable of serving flexible and fixed sized ads in the placement. The new [Adaptive Banner]([/en/mediation/ad-types/#adaptive-banner/](https://docs.chartboost.com/en/mediation/ad-types/#adaptive-banner/)) ad format has the following features:
+- Publishers can choose whether to use Adaptive Ads or Fixed Ads in a given placement.
+- Fixed Ads are supported in Adaptive Ad placements (backwards compatible).
+- Publishers should know whether an ad is fixed or flexible and receive the dimensions of fixed ads.
+- Publishers can align the ad horizontally and/or vertically.
+- Publishers can resize the ad container to fit the ad or optionally discard oversized ads that are rendered in the container.
+- The ad container can be in-line or on top of publisher content.
+
+To use this new ad format, Publishers will need to create a new Adaptive Banner placement in their platform and integrate with the new Adaptive Banner APIs.
+
+> **Caution** \
+> Google Bidding does not support 0 height adaptive banner sizes and will result in no fill.
+
+
+We have added a new Banner API `ChartboostMedaitionBannerView` to allow usage of adaptive banners. The previous `ChartboostMedaitionBannerAd` API has now been deprecated.
 
-Since Chartboost Mediation Unity SDK 4.6.X we have deprecated the previous approach for loading banner placements. A new Banner API `ChartboostMedaitionBannerView` has been provided which makes use of C# asycn/await methods in order to await for load and show and also provides support to load adaptive size banners.
 
 Another API `ChartboostMediationUnityBannerAd` is also provided which allows usage of unity gameobjects to load a banner ad within it.
 
+The API class `ChartboostMediationBannerSize` will support both fixed and adaptive banners:
+
+|Field|Description|
+|--|--|
+|`static ChartboostMediationBannerSize Standard`|Static constant that returns a fixed `STANDARD` banner with a size of 320x50.|
+|`static ChartboostMediationBannerSize MediumRect`|Static constant that returns a fixed MREC `MEDIUM` banner with a size of 300x250.|
+|`static ChartboostMediationBannerSize Leaderboard`|Static constant that returns a fixed `LEADERBOARD` banner with a size of 728x90.|
+|`ChartboostMediationBannerType BannerType`|An enum specifying that the ad size is fixed (size cannot change), or adaptive (size can change but must maintain aspectRatio). This is an integer based enum.|
+|`float Width`|The width of the ad.|
+|`float Height`|The height of the ad.|
+|`float AspectRatio`|The aspect ratio of the ad. This can be derived from the size. Will be 0 if either the width or the height are <= 0.|
+|`static ChartboostMediationBannerSize Adaptive(float width)`|Creates a flexible/adaptive banner size with 0 height.|
+|`static ChartboostMediationBannerSize Adaptive(float width, float height)`|Creates a flexible/adaptive banner size with a width and max height. Used either when the height of an inline ad should be capped, or when requesting an anchored banner.|
+|`<additional conveniences>`|This provides additional conveniences to create sizes based on the IAB ratios (e.g. 6:1, 1:1) with a width. For example, using the 6:1 convenience with a 600 width would return a size of 600x100. Note that these are max sizes, therefore smaller sizes or other aspect ratios may be served.|

 ## Clearing Loaded Ads
 
 Sometimes, you may need to clear loaded ads on existing placements to request another ad (i.e. for an in-house programmatic auction). To do this:
