+# `@tryabby/vue`
+
+Typed Vue 3 integration for [Abby](https://tryabby.dev) A/B testing, feature flags, and remote configuration.
+
+## Client-Only Usage (SPA)
+
+```ts
+import { createAbby } from "@tryabby/vue";
+
+export const { plugin, useAbTest, useFeatureFlag, useRemoteConfig } = createAbby({
+  projectId: "YOUR_PROJECT_ID",
+  currentEnvironment: "production",
+  environments: ["production", "development"],
+  tests: {
+    headerTest: { variants: ["A", "B"] },
+  },
+  flags: ["darkMode"],
+  remoteConfig: {
+    maxItems: "number",
+  },
+});
+```
+
+## SSR Usage (Per-Request Instance)
+
+In SSR environments (e.g., Nuxt / Vite SSR), create a fresh Abby instance per request so `updateUserProperties` and state are never shared across concurrent requests:
+
+```ts
+import { createSSRApp } from "vue";
+import { createAbby } from "@tryabby/vue";
+import App from "./App.vue";
+
+export function createApp() {
+  const app = createSSRApp(App);
+  const abby = createAbby({
+    projectId: "YOUR_PROJECT_ID",
+    currentEnvironment: "production",
+    environments: ["production", "development"],
+    tests: { headerTest: { variants: ["A", "B"] } },
+    flags: ["darkMode"],
+    remoteConfig: { maxItems: "number" },
+  });
+  app.use(abby.plugin);
+  return { app, abby };
+}
+```
