Is the sfcc documentation publicly available?

 Commerce Cloud documentation is available in the Commerce Cloud XChange site and what is often called: Infocenter. The prior is somewhat analogous to Salesforce SE whereas the latter is more traditional API documentation and product manuals. Infocenter is publicly available as of January 2019. In order to access XChange, you must have an Account Manager credential that is granted by a partner or customer organisation that has a standing contract with Commerce Cloud. Additionally, the support team has developed some Knowledge Base Articles that are accessible if a customer or partner organisation has created a Support account for you. These articles are supplementary to the Infocenter documentation.
