+## JSON Schema
+
+You can validate your `.all-contributorsrc` configuration file using the JSON schema available on [SchemaStore](https://www.schemastore.org/all-contributors.json).
+
+This helps in catching configuration errors early and provides auto-completion in compatible editors (like VS Code).
+
+Example `.all-contributorsrc` with `$schema` added:
+
+```json
+{
+  "$schema": "https://www.schemastore.org/all-contributors.json",
+  "projectName": "all-contributors",
+  "projectOwner": "all-contributors",
+  "repoType": "github",
+  "repoHost": "https://github.com",
+  "files": ["README.md"],
+  "imageSize": 100,
+  "commit": false,
+  "contributorsPerLine": 7,
+  "contributorsSortAlphabetically": false,
+  "badgeTemplate": "[![All Contributors](https://img.shields.io/github/all-contributors/<%= projectOwner %>/<%= projectName %>?color=ee8449&style=flat-square)](#contributors)",
+  "contributorTemplate": "<a href=\"<%= contributor.profile %>\"><img src=\"<%= contributor.avatar_url %>\" width=\"<%= options.imageSize %>px;\" alt=\"\"/><br /><sub><b><%= contributor.name %></b></sub></a>",
+  "wrapperTemplate": "\n<table>\n  <tbody><%= bodyContent %>  </tbody>\n<%= tableFooterContent %></table>\n\n",
+  "types": {
+    "custom": {
+      "symbol": "🔭",
+      "description": "A custom contribution type.",
+      "link": "[<%= symbol %>](<%= url %> \"<%= description %>\"),"
+    }
+  },
+  "linkToUsage": true,
+  "skipCi": true,
+  "contributors": []
+}
+```
