 ## Under the hood
 
-SafeDI has a `SafeDITool` executable that the `SafeDIGenerator` plugin utilizes to read code and generate a dependency tree. The tool utilizes Apple‘s [SwiftSyntax](https://github.com/apple/swift-syntax) library to parse your code and find your `@Instantiable` types‘ initializers and dependencies. With this information, SafeDI creates a directed, acyclic graph of your project‘s dependencies. This graph is validated as part of the `SafeDITool`‘s execution, and the tool emits human-readible errors if the dependency graph is not valid. Source code is only generated if the dependency graph is valid.

 The executable heavily utilizes asynchronous processing to avoid `SafeDITool` becoming a bottleneck in your build. Additionally, we only parse a Swift file with `SwiftSyntax` when the file contains the string `Instantiable`.
