 # codeflare-common
 Common packages for use with CodeFlare Distributed Workload stack.
+
+## GitHub actions collection
+Folder github-actions contains collection of GitHub composite actions which can be reused in other repositories.
+This approach is used to keep all the usable actions on one place, unlike from default usage when every action is located in dedicated repository.
+
+Usage:
+- Clone CodeFlare common repository
+- Refer to the action file using `uses` step parameter pointing to the local folder path with action.yml
+
+### KinD GitHub action
+GitHub action which spins up KinD cluster with Ingress and local registry available in the cluster.
+
+Action creates environment variables:
+- `TEMP_DIR` - helper env variable, pointing to local temporary directory
+- `REGISTRY_ADDRESS` - hostname of the locally available insecure registry
+- `KIND_CONFIG_FILE` - helper env variable, pointing to the KinD config file
+- `CLUSTER_TYPE` - type of cluster, hardcoded to `KIND`
+- `CLUSTER_HOSTNAME` - hostname of the KinD cluster
