+# Indy sidecar init
+**Deployment**
+
+The sidecar init container is meant to be init-container part of builder and sidecar pod, provides sidecar with initial repos downloaded from archive service.
+
+1. Make sure you have right application.yaml from [indy-sidecar](https://github.com/commonjava/indy-sidecar) container, you must set `sidecar.archive-api` and `sidecar.local-repository` for this to work.
+
+2. mount the same application.yaml across this sidecar-init container as well as the sidecar container.
+
+3. Add init-container part to the pod deploymentconfig and mount preSeedRepo volume as the sidecar does (or whatever defined it in application.yaml config file)
+
+Template of the deployment can be found in template/template-sidecar.yaml
+
+---
+
+**Build container image**
+
+Use Dockerfile or BuildConfig.yaml(for Openshift) to build the container
