+# Declarative Gradle DSL
+
+This branch has been modified to work with the prototype of the Declarative Gradle DSL.
+
+## Feedback on basics
+
+- "Hybrid" mode where some projects can use declarative files and some do not
+- Ecosystem plugin in settings file and software type in declarative project file
+- Importable and buildable (e.g., gradle build works)
+- Syntax highlighting available in Android Studio
+- Demonstrate NowInAndroid has at least one project file converted
+
+## Setup
+
+```
+git clone https://github.com/gradle/nowinandroid.git
+cd nowinandroid
+git clone https://github.com/gradle/declarative-gradle.git
+```
+
+This should checkout the `main` branch of [declarative-gradle](https://github.com/gradle/declarative-gradle) inside the **root** of a NowInAndroid fork.
+
+```
+nowinandroid/
+    declarative-gradle/
+```
+
+### Building the project
+
+You can assemble the project with the following command:
+
+```shell
+./gradlew buildDemoDebug
+```
+
+### Running tests
+**Note:** See the note in [Screenshot tests](#screenshot-tests) about setting up Roborazzi for non-Linux test runs.
+
+```shell
+./gradlew testDemoDebug :lint:test
+```
+
+```shell
+./gradlew testDemoDebugUnitTest -Proborazzi.test.verify=false
+```
+
+After starting a local Android emulator in Android Studio:
+```shell
+./gradlew connectedDemoDebugAndroidTest --daemon
+````
