# Installation

> How an ORCA installation runs — from verified release package to healthy pipeline.

ORCA installs from a **signed, versioned release package** ([contents & verification](/platform/release/release-package)) via Helm onto your Kubernetes — in-tenant, sovereign, or fully [air-gapped](/orca/deployment/air-gapped).

## The installation flow

<Steps>
  <Step title="Verify the release package">Checksums and cosign signature — supply-chain integrity before anything runs.</Step>
  <Step title="Prepare the cluster">Namespaces, secrets, storage per the [prerequisites](/orca/deployment/requirements).</Step>
  <Step title="Deploy datastores and streaming layer">Or attach existing estate services — no rip-and-replace.</Step>
  <Step title="Deploy ORCA services and the control tower">Self-monitoring is installed with the platform, not after it.</Step>
  <Step title="Connect the first source and validate the healthy shape">Event volume must decrease monotonically across stages before a second source is added.</Step>
</Steps>

The complete step-by-step guide — commands, values files, verification checks per step — ships inside the release package and the customer portal, versioned with each release. Installation of production deployments is performed jointly with Doblier engineers as part of the [go-live gate framework](/orca/readiness/go-live-gates).
