+
+### Clone repository
+
+```sh
+git clone https://github.com/an-anime-team/components
+```
+
+### Modify index
+
+#### Components index (`components.json`):
+
+```ts
+{
+    wine: Wine[],
+    dxvk: Dxvk[]
+}
+```
+
+```ts
+type Wine = {
+    name: string,
+    title: string,
+    ?features: {
+        ?no_dxvk: boolean,
+        ?env: {
+            [id: string]: string
+        }
+    }
+}
+```
+
+```ts
+type Dxvk = {
+    name: string,
+    title: string,
+    ?features: {
+        ?env: {
+            [id: string]: string
