 The `TemplateCompiler` can produce a template function from a string without additional information. However, correct interpretation of that string requires a selector scope discussed below. The selector scope is built at runtime allowing the runtime to use a function built from just a string as long as it is given a selector scope (e.g. an NgModule) to use during instantiation.
 
-#### The selector problem 
+#### The selector problem
 
 To interpret the content of a template, the runtime needs to know what component and directives to apply to the element and what pipes are referenced by binding expressions. The list of candidate components, directives and pipes are determined by the `NgModule` in which the component is declared. Since the module and component are in separate source files, mapping which components, directives and pipes referenced is left to the runtime. Unfortunately, this leads to a tree-shaking problem. Since there no direct link between the component and types the component references then all components, directives and pipes declared in the module, and any module imported from the module, must be available at runtime or risk the template failing to be interpreted correctly. Including everything can lead to a very large program which contains many components the application doesn't actually use.

+# Delta Instructions
+
+Ivy exports a number of functions prefixed with `Δ`, for example `ΔelementStart`, or `Δinject`, et al. These functions are referred to an "instructions" or "delta" instructions. They are functions that are called by code generated by the Ivy compiler that must be publicly exposed in order to be consumed by this generated code. **They are not meant for developer consumption**. The reason they are prefixed with `Δ` is not only to identify them as different from other functions, but also to make them not show up at the top of IDE code completion in environments such as Visual Studio code.
+
+
+### Guidance
+
+- Do not use `Δ` functions directly. They are meant to be used in generated code.
+- Do not create new `Δ` functions, it's not a convention that Angular consumes, and it is liable to confuse other developers into thinking consuming Angular's `Δ` functions is a good pattern to follow.

 An interesting thing about these objects is that they are not memoized `injector.get(ElementRef) !== injector.get(ElementRef)`.
