+Get a SpacetimeDB Nuxt app running in under 5 minutes.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) 18+ installed
+- [SpacetimeDB CLI](https://spacetimedb.com/install) installed
+
+<InstallCardLink />
+

+
+<StepByStep>
+  <Step title="Create your project">
+    <StepText>
+      Run the `spacetime dev` command to create a new project with a SpacetimeDB module and Nuxt client.
+
+      This will start the local SpacetimeDB server, publish your module, generate TypeScript bindings, and start the Nuxt development server.
+    </StepText>
+    <StepCode>
+```bash
+spacetime dev --template nuxt-ts
+```
+    </StepCode>
+  </Step>
+
+  <Step title="Open your app">
+    <StepText>
+      Navigate to [http://localhost:5173](http://localhost:5173) to see your app running.
+
+      The template includes a basic Nuxt app connected to SpacetimeDB.
+    </StepText>
+  </Step>
+
+  <Step title="Explore the project structure">
+    <StepText>
+      Your project contains both server and client code.
+
+      Edit `spacetimedb/src/index.ts` to add tables and reducers. Edit `components/AppContent.vue` to build your UI, and `app.vue` to configure the SpacetimeDB connection.
+    </StepText>
+    <StepCode>
+```

+├── spacetimedb/          # Your SpacetimeDB module
+│   └── src/

+├── nuxt.config.ts        # Nuxt configuration
+└── package.json
+```
+    </StepCode>
+  </Step>
+
+  <Step title="Understand tables and reducers">
+    <StepText>
+      Open `spacetimedb/src/index.ts` to see the module code. The template includes a `person` table and two reducers: `add` to insert a person, and `say_hello` to greet everyone.
+
+      Tables store your data. Reducers are functions that modify data — they're the only way to write to the database.
+    </StepText>
+    <StepCode>
+```typescript
+import { schema, table, t } from 'spacetimedb/server';
+
+export const spacetimedb = schema(
+  table(
+    { name: 'person', public: true },
+    {
+      name: t.string(),
+    }
+  )
+);
+
+spacetimedb.reducer('add', { name: t.string() }, (ctx, { name }) => {
+  ctx.db.person.insert({ name });
+});
+
+spacetimedb.reducer('say_hello', (ctx) => {
+  for (const person of ctx.db.person.iter()) {
+    console.info(`Hello, ${person.name}!`);
+  }
+  console.info('Hello, World!');
+});
+```
+    </StepCode>
+  </Step>
+
+  <Step title="Test with the CLI">
+    <StepText>
+      Use the SpacetimeDB CLI to call reducers and query your data directly.
+    </StepText>
+    <StepCode>
+```bash
+# Call the add reducer to insert a person
+spacetime call <database-name> add Alice
+
+# Query the person table
+spacetime sql <database-name> "SELECT * FROM person"
+ name
+---------
+ "Alice"
+
+# Call say_hello to greet everyone
+spacetime call <database-name> say_hello
+
+# View the module logs
+spacetime logs <database-name>
+2025-01-13T12:00:00.000000Z  INFO: Hello, Alice!
+2025-01-13T12:00:00.000000Z  INFO: Hello, World!
+```
+    </StepCode>
+  </Step>
