 A simple webapp for building Kubernetes resource definitions using a form.
 
+Developed using VueJS and TailwindCSS. Built mostly as a side-project for learning, but pull requests are welcome!
+
+**Currently (25/10):** researching how to populate the forms dynamically from JSON, so that more dynamic and complex Kubernetes objects can be created.
+
 You can find this running at: https://tomd.xyz/tools/kubernetes-manifest-builder/
