With the release of AEM 6.2 in 2016, Adobe announced that they have a new example site called We.Retail. Unfortunately We.Retail did not come prebaked into Adobe Experience Manager and it requires a separate install. I expect that to change for future releases of AEM, but until then, Jayan Kandathil has outlined how to install it in his blog post: “How to Install the new AEM 6.2 We.Retail Reference Site”. Go check it out.
