+# GCP SCTFE CI Environment
+
+## Overview
+
+This config uses the [gcp/conformance](/deployment/modules/gcp/conformance) module to
+define a CI environment to run the SCTFE, backed by Trillian Tessera.
+
+At a high level, this environment consists of:
+- One Spanner instance with two databases:
+  - one for Tessera
+  - one for deduplication
+- A GCS Bucket
+- Secret Manager
+- Cloud Run
+
+### Manual Deployment
+
+First authenticate via `gcloud` as a principle with sufficient ACLs for
+the project:
+
+```sh
+gcloud auth application-default login
+```
+
+Set the required environment variables:
+
+```sh
+export GOOGLE_PROJECT={VALUE}
+export GOOGLE_REGION={VALUE} # e.g: us-central1
+```
+
+TODO: Add the Artifact Registry which is in the Cloud Build pull request. The expected repository is `us-central1-docker.pkg.dev/${GOOGLE_PROJECT}/docker-ci`.
+
+Build and push the Docker image to Artifact Registry repository:
+
+```sh
+docker build -f ./cmd/gcp/Dockerfile -t sctfe-gcp:latest .
+docker build -f ./cmd/gcp/ci/Dockerfile -t conformance-gcp:latest .
+docker tag conformance-gcp:latest us-central1-docker.pkg.dev/${GOOGLE_PROJECT}/docker-ci/conformance-gcp:latest
+docker push us-central1-docker.pkg.dev/${GOOGLE_PROJECT}/docker-ci/conformance-gcp
+```
+
+Terraforming the project can be done by:
+  1. `cd` to the relevant directory (/deployment/live/gcp/ci/) for the environment to deploy/change.
+  2. Run `terragrunt apply`.
