It helps to be aware of the following concepts before reading though the getting started pages.
Fast Healthcare Interoperability Resources (FHIR, pronounced "fire") is a standard describing data formats and elements (known as "resources") and an application programming interface (API) for exchanging electronic healthcare data. The Commure Platform uses the FHIR standard to represent all clinical data.

The SMART application launch protocol serves two primary purposes. First, it allows applications to be tightly integrated into provider workflow by allowing them to be embedded within the electronic health record (EHR). Second, SMART allows providers to use their existing health system credentials to sign into a Commure Platform application, providing a seamless, single sign-on user experience.
When logging into an application launched using your Commure tenant, you will be prompted to log in using your Commure Developer account. However, when a provider launches the application in production, they will prompted to sign in using their existing credentials. If they are already signed into the EHR, they will not be prompted to sign in again.
