+# Bumble Tech Live Mosaic Challenges
+
+## Do you want to win a prize?
+
+The following are a set of exciting challenges for you to tackle. They’re designed to test your
+skills, foster innovation, and offer attractive prizes. Go ahead, participate, and win!
+
+## Jetpack Compose challenges
+
+1. **C01 – Migrate** [`composed`](https://developer.android.com/reference/kotlin/androidx/compose/ui/package-summary#\(androidx.compose.ui.Modifier\).composed\(kotlin.Function1,kotlin.Function1\))
+ **modifiers to** [`Modifier.Node`](https://developer.android.com/reference/kotlin/androidx/compose/ui/Modifier.Node)
+
+   * *Description*: [The Jetpack Compose team is migrating](https://youtu.be/BjGX2RftXsU?feature=shared\&t=920) 
+     `composed` Modifiers to `Modifier.Node` to increase the performance of Compose apps. Find 
+     `composed` Modifiers in the project, and convert them to `Modifier.Node`.
+   * *Example in the Compose codebase*: [PR of the Modifier.background migration](https://android-review.googlesource.com/c/platform/frameworks/support/+/2440999).
+
+2. **C02 – Transition between nodes using other shapes**
+
+   * *Description*: Take a look at how the current transition effect has been implemented in 
+     `DottedMeshShape`. This class utilises circles, but it would be nice to allow also other shapes: 
+     for instance hexagons. Extend the class to support at least circles and hexagons.
+
+## Performance challenges
+
+1. **P01 – Measure the performance of the app**
+
+   * *Description*: We want a way to inspect and monitor the performance of Puzzyx. 
+     [Setup macrobenchmark](https://developer.android.com/topic/performance/benchmarking/macrobenchmark-overview#project-setup) 
+     in the project and [add tests](https://developer.android.com/topic/performance/benchmarking/macrobenchmark-overview#create-macrobenchmark)
+     to the project that check its startup time.
+
+2. **P02 – Add baseline profiles to Puzzyx**
+
+   * *Description*: We want to improve the code execution of Puzzyx by shipping baselines profiles 
+     when the app is run. [Create baseline profiles](https://developer.android.com/topic/performance/baselineprofiles/create-baselineprofile)
+     for the app and [benchmark](https://developer.android.com/topic/performance/baselineprofiles/create-baselineprofile#benchmark-baseline-profile) 
+     the performance improvements.
+
+## Build & CI challenges
+
+1. **B01 – Add Detekt and Compose rules**
+
+   * *Description*: Integrate [Detekt](https://detekt.dev) and [Compose Rules](https://mrmans0n.github.io/compose-rules/)
+     into the project, enhancing source code quality. Your challenge involves embedding Detekt for
+     static analysis, incorporating Compose Rules for Jetpack Compose issue detection, and refining
+     the existing codebase. Furthermore, you'll adapt Github Actions to include these verification
+     processes in the current build workflow.
