+KonTemplate - A simple Kubernetes templater
+===========================================
+
+I made this tool out of frustration with the available ways to template Kubernetes resource files. All I want out of
+such a tool is a way to specify lots of resources with placeholders that get filled in with specific values, based on
+which context (i.e. k8s cluster) is specified.
+
+## Overview
+
+KonTemplate lets you describe resources as you normally would in a simple folder structure:
+
+```
+.
+├── prod-cluster.json
+└── some-api
+    ├── deployment.yaml
+    └── service.yaml
+```
+
+This example has all resources belonging to `some-api` (no file naming conventions enforced at all!) in the `some-api`
+folder and the configuration for the cluster `prod-cluster` in the corresponding file.
+
+Lets take a short look at `prod-cluster.json`:
+
+```json
+{
+  "context": "k8s.prod.mydomain.com",
+  "include": [
+    {
+      "name": "some-api",
+      "values": {
+        "importantFeature": true,
+        "apiPort": 4567
+      }
+    }
+  ]
+}
+```
+
+
+Those values are then templated into the resource files of `some-api`.
+
+## Usage
+
+You must have `kubectl` installed to use KonTemplate.
