+# Setup
+
+This plugin automatically adds the lint to all modules defined in the whole project and
+use [lint.xml](../../lint.xml) as the single source of truth to configure the lints in every app
+
+To enable these compose lints in a new project, follow these steps:
+
+1. Make sure your top level settings.gradle.kts defines the following if not already done in order to import Core's composite
+   build:
+
+```kts
+pluginManagement {
+    includeBuild("Core/build-logic")
+}
+```
+
+2. Inside the top-level build.gradle.kts add the following plugin:
+
+```kts
+plugins {
+    id("com.infomaniak.core.compose.lint")
+}
+```
+
+And you're done!
