 # Robespierre
 
 Robespierre is a tool built in RUST and packaged via NPM that helps you find extraneous and implicit dependencies by 
-comparing your manifest and actual imports in your code using AST parsing.
+comparing your manifest and actual imports in your **typescript** code using AST parsing.
+
+* An *extraneous* dependency is a dependency declared in you `package.json` manifest, but unused in you code
+* An *implicit* dependency is the opposite. A dependecy used somewhere in your codebase via an import statement, but not declared in your `package.json`. It can work somehow, 'cause it's installed indirectly by another dependency, but this is a bad practice.
+
+Robespierre is focused on performance and uses [SWC](https://github.com/swc-project/swc) typescript AST parser to browse your codebase efficiently.
+
+> The name "robespierre" is a humorous reference to Maximilien de Robespierre, a significant political figure in the French Revolution. Known for prolifically using the guillotine, our binary borrows its name because it helps you figure out which dependency's head to cut off!
