+## DevOps Take Home Task
+
+1. Fork the following repo:
+    1. go-ethereum (geth) https://github.com/ethereum/go-ethereum
+2. Update your forked repo with the following functionality:
+    1. When a PR with label `CI:Build` is merged in it, a trigger kicks in and:
+        1. builds a new docker image of the given project
+        2. uploads it to a registry
+    2. Create a Docker Compose definition that runs a local devnet with the newly built image.
+3. Create e new directory named `hardhat` in the repository. Inside it start a new **Sample Hardhat Project** (*following official Hardhat docs*)
+    1. When a PR with label `CI:Deploy` is merged in the repo, a pipeline is triggered that
+        1. runs a local devnet using the forked `go-ethereum` image.
+        2. deploys the Sample Hardhat Project to it.
+        3. builds a new docker image, which allows to run an instance of the devnet with the contracts already deployed and uploads it to the same registry with a suitable different tag
+4. Add a step to the pipeline which runs the hardhat tests from the sample project against the image with predeployed contracts 
+5. Create a Terraform script that quickly creates a k8s cluster in the cloud and deploys an instance of the built image to it.
+6. (Bonus) Add Blockscout explorer to the Docker Compose definition created
+
