+
+<!-- end auto-generated rule header -->
+
+This rule checks for the existence of the `"repository"` property in a package.json, and reports a violation if it doesn't exist.
+
+Example of **incorrect** code for this rule:
+
+```json
+{
+	"name": "thee-silver-mt-zion",
+	"version": "13.0.0"
+}
+```
+
+Examples of **correct** code for this rule:

+	"repository": "github:owner/project"
+}
+```
+
+```json

+	"name": "thee-silver-mt-zion",

+<!-- end auto-generated rule options list -->
+
+You can set the `ignorePrivate` option to `true` to ignore package.json files with `"private": true` (default: `false`).
