 ## What is Bicep?
 
-Bicep is a Domain Specific Language (DSL) for deploying Azure resources declaratively. It aims to drastically simplify the authoring experience with a cleaner syntax, improved type safety, and better support for modularity and code re-use. Bicep is a **transparent abstraction** over ARM and ARM templates, which means anything that can be done in an ARM Template can be done in Bicep (outside of temporary [known limitations](#known-limitations)). All resource `types`, `apiVersions`, and `properties` that are valid in an ARM template are equally valid in Bicep on day one.

 Bicep code is transpiled to standard ARM Template JSON files, which effectively treats the ARM Template as an Intermediate Language (IL).

 * No support for single-line object and arrays (i.e. `['a', 'b', 'c']`) ([#586](https://github.com/Azure/bicep/issues/586)).
 * Bicep is newline sensitive. We are exploring ways we can remove/relax this restriction ([#146](https://github.com/Azure/bicep/issues/146))
 * No support for the concept of apiProfile which is used to map a single apiProfile to a set apiVersion for each resource type. We are looking to bring support for this type of capability, but suspect it will work slightly differently. Discussion is in [#622](https://github.com/Azure/bicep/issues/622)
-* No support for key vault references in modules, even though this is possible with nested deployments in ARM Templates. ([#1028](https://github.com/Azure/bicep/issues/1028))
