+## Local deployment (lcl)
+
+The `lcl` environment is the developer's own single-node **k3s** cluster used for
+local integration testing. It is defined by `deploy/helm/go-bananas/values-lcl.yaml`:
+
+- `config.environment: development` so the local auth bypass is allowed.
+- `identity.mode: dev` so you can sign in without an OIDC provider.
+- `image.registry: localhost:5000` so the cluster pulls from a local registry.
+- Ingress host `bananas-lcl.intern-urpi.be`, terminated by the local TLS edge.
+
+All the `go-*` applications share the **`go-insane-lcl`** namespace; go-bananas is a
+Helm release named `go-bananas` inside it.
+
+### Prerequisites
+
+1. A running local k3s cluster and a registry at `localhost:5000`.
+2. `bananas-lcl.intern-urpi.be` resolving to the node (`/etc/hosts`) behind the TLS edge.
+3. `docker buildx`, `helm` and `kubectl`.
+
+> **Kubeconfig caveat.** On this machine the default `local` context goes through a
+> Rancher proxy (`https://rancher.urpi.be/k8s/clusters/local`) which can 502. When it
+> does, talk to k3s directly instead: `export KUBECONFIG=/etc/rancher/k3s/k3s.yaml`.
+> Everything below respects that variable.
+
+### One-shot build + deploy + verify
+
+```bash
+KUBECONFIG=/etc/rancher/k3s/k3s.yaml ./hack/deploy-lcl.sh
+# or, equivalently:
+KUBECONFIG=/etc/rancher/k3s/k3s.yaml make deploy-lcl
+```
+
+This builds a fresh image (with the web admin UI and runtime SDK compiled in), pushes
+it to the local registry, runs `helm upgrade --install`, waits for the rollout, and
+curls the runtime manifest through the TLS edge. The image tag defaults to a build
+timestamp so a rebuild is always re-pulled (`IfNotPresent` would otherwise serve a
+stale cached tag). Override it with `LCL_TAG=...`.
+
+### Step by step
+
+```bash
+make install             # Go and Node dependencies
+make image-lcl           # build + push to localhost:5000/go-bananas:<LCL_TAG>
+make helm-template-lcl   # sanity-check the rendered manifest
+make helm-install-lcl    # helm upgrade --install into go-insane-lcl
+```
+
+`LCL_TAG`, `LCL_REGISTRY` and `LCL_NAMESPACE` are overridable:
+
+```bash
+make deploy-lcl LCL_TAG=v1 LCL_REGISTRY=registry:5000 LCL_NAMESPACE=go-insane-lcl
+```
+
+### Sign in and verify
+
+The release uses `dev` authentication, so any user is a local administrator. Open
+`https://bananas-lcl.intern-urpi.be/?dev-user=you@example.test`, then:
+
+```bash
+curl -sk https://bananas-lcl.intern-urpi.be/readyz
+curl -sk https://bananas-lcl.intern-urpi.be/rt/v1/manifest.json | jq '.themes[].slug'
+```
+
+### Remove
+
+```bash
+KUBECONFIG=/etc/rancher/k3s/k3s.yaml make helm-uninstall-lcl
+```
