+
+## Setting up the environment
+
+To set up the environment, navigate to the root of the repository and run:
+
+```bash
+export RANCHER_HOSTNAME="<hostname>"
+export NGROK_API_KEY="<api-key>"
+export NGROK_AUTHTOKEN="<api-authtoken>"
+
+make dev-env
+```
+
+The `Makefile` target sets up the environment by executing the `scripts/etcd-backup-restore-dev.sh`
+script with the `RANCHER_HOSTNAME` argument. Under the hood, it performs the following steps:
+
+1. Creates a kind cluster.
+2. Deploys cert-manager, CAPI Operator with Rancher Turtles.
+3. Deploys CAPRKE2 provider.
+4. Deploys Docker provider.
+5. Deploys ngrok.
+6. Deploys Rancher accessible via ngrok.
+
+Environment is prepared for cluster creation using CAPRKE2. UI is accessible via `RANCHER_HOSTNAME`.
+
+## Creating a cluster
+
+To deploy an RKE2 cluster with automatic snapshots enabled:
+
+```bash
+export CONTROL_PLANE_MACHINE_COUNT=1
+export WORKER_MACHINE_COUNT=1
+export CLUSTER_NAME=rke2
+export KUBERNETES_VERSION=v1.30.4
+export RKE2_VERSION=v1.30.4+rke2r1
+
+# Prevent replacing lb-config variables by envsubst
+export address='$address'
+export server='$server'
+
+envsubst < test/e2e/data/cluster-templates/docker-rke2.yaml | kubectl apply -f -
+```
+
+## Performing the snapshot and restore
+
+When all machines in the cluster are ready, automatic ETCDMachineSnapshot object should appear on the management cluster soon.
+
+```bash
+
+kubectl get etcdmachinesnapshot -A
+```
+
+To perform a restore run the following command:
+
+```bash
+export CLUSTER_NAMESPACE=default
+export CLUSTER_NAME=rke2
+export ETCD_MACHINE_SNAPSHOT_NAME="<snapshot_name_from_the_output>"
+
+envsubst < etcdrestore/examples/etcd-restore.yaml | kubectl apply -f -
+```
+
+## Cleanup
+
+To clean up the environment, run the following command from the root of the repo:
+
+```bash
+make clean-dev-env
+```
