+# Facade
+
+A simple tool that injects interfaces into a jar file.
+This is meant to be a build time tool to transform dependencies adding new interfaces.
+Allowing your code to compile against the injected code as if it was a normal dependency.
+
+This uses the ClassFile API and so needs java 25+
+
+## Usage
+
+```shell
+java -jar facade.jar --input dependency.jar --output patched.jar --config interfaces.cfg
+```
+
+## Gradle
+Currently there is no gradle demo/plugin for this, as the intended use is through [ForgeGradle][ForgeGradle] and [Mavenzier][Mavenizer].
+
+> [!WARNING]
+> **There is no public API for this tool!** This is designed to solely be a CLI tool, which means that all of the implementations are internal. We reserve the right to change the internal implementation at any time.
