 [`@babel/core`](/packages/babel-core) is the Babel compiler itself; it exposes the `babel.transform` method, where `transformedCode = transform(src).code`.
 
 The compiler can be broken down into 3 parts:
-- The parser: [`babylon`](/packages/babylon)
+- The parser: [`@babel/parser`](/packages/babel-parser)
 - The transformer[s]: All the plugins/presets
   - These all use [`@babel/traverse`](/packages/babel-traverse) to traverse through the AST
 - The generator: [`@babel/generator`](/packages/babel-generator)
 
 The flow goes like this:
 
-input string -> `babylon` parser -> `AST` -> transformer[s] -> `AST` -> `@babel/generator` -> output string
+input string -> `@babel/parser` parser -> `AST` -> transformer[s] -> `AST` -> `@babel/generator` -> output string
 
 Check out the [`babel-handbook`](https://github.com/thejameskyle/babel-handbook/blob/master/translations/en/plugin-handbook.md#introduction) for more information on this.
