+### Create different Radars
+To create different radars with one set of blips put a `radars` entry in your frontmatter:
+```yaml
+---
+title: Item
+ring: adopt
+quadrant: tools
+radars: [radar-1, radar-2]
+---
+```
+
+Then, to select the blips put a `radar` entry in the `config.json` for generating the site:
+```json
+{
+  "radar": "radar-1",
+  "quadrants": {
+    ...
+```
+
+This will only add blips with the defined radar into the output.
