+# Example OpenTofu config for the hpe1810 provider
+
+Run this once the switch is reachable again.
+
+## 1. Build the provider
+
+```bash
+cd ../terraform-provider-hpe1810
+go build -o terraform-provider-hpe1810 .
+```
+
+`~/.tofurc` already has a `dev_overrides` entry pointing at that directory, so `tofu`
+picks up this locally-built binary instead of trying to fetch anything from a registry.
+
+## 2. Plan
+
+```bash
+cd ../terraform  # this directory
+tofu plan
+```
+
+No `tofu init` needed (and it would fail anyway — `local/joachimfriberg/hpe1810` isn't a
+real registry source) since `dev_overrides` bypasses that step entirely.
+
+You'll see a warning about dev overrides being in effect — that's expected during local
+development, not an error.
+
+## Files here
+
+- `versions.tf` — `required_providers` block, points at the provider source name.
+- `provider.tf` — `provider "hpe1810"` block; all fields optional (see comments for the
+  env-var fallback chain).
+- `main.tf` — the actual data source usage.
+- `outputs.tf` — prints what came back.
+
+## Remember
+
+- Only one login session to the switch at a time (see AGENT.md) — close the switch's web
+  UI in your browser before running `tofu plan`.
+- Same proxy issue as the Python project: Go's `net/http` also respects `HTTP_PROXY`/
+  `NO_PROXY`. If you get `login request returned status 502`, run
+  `export NO_PROXY=192.168.2.10` (or `no_proxy=192.168.2.10`) before `tofu plan`.
