+## Terraform Modules
+
+Open `/terraform-modules/` to explore public AWS Terraform modules
+maintained by the native-cube GitHub organization. The catalogue covers Amazon
+EKS, EKS Auto Mode, managed node groups, Fargate profiles, KMS, and VPC Flow
+Logs, with direct links to each GitHub repository and Terraform Registry page.
+
+Module names, descriptions, categories, and visual treatments are maintained in
+`terraform-modules/modules.json`. Registry versions, release dates, required
+inputs, Terraform and AWS requirements, and GitHub status are synchronized into
+the same file and used to generate the module cards and structured data.
+
+Refresh live metadata and regenerate the page:
+
+```sh
+python3 scripts/sync-terraform-modules.py --write
+```
+
+Regenerate from local catalogue data without network access, or verify live data
+and committed HTML without changing files:
+
+```sh
+python3 scripts/sync-terraform-modules.py --render
+python3 scripts/sync-terraform-modules.py --check
+```
+
+To add a module, add its curated entry to `modules.json`, publish the matching
+`terraform-aws-<name>` repository and Registry module, then run `--write`. The
+weekly catalogue workflow also reports Registry, GitHub, or generated-page drift.
+
+The dedicated social card is maintained as an editable SVG. On macOS, regenerate
+its required 1200×630 PNG with:
+
+```sh
+sh scripts/render-social-card.sh
+```
