+Great, now I need to generate images for this. Before I used the following prompts (2 releases before).

+// An image of a capybara sculpted entirely from black cotton candy, set against a minimalist backdrop with splashes of bright, contrasting sparkles. The capybara is using a computer with split screen made of origami, split keyboard and is wearing origami sunglasses with very different split reflections. Split halves are very contrasting. Close up photography, bokeh, white background.

 ### LocalAI installation and configuration

 Follow the guide at: https://localai.io/basics/getting_started/

+  (or the IP:Port of the machine, if running remotely) and seeing listed the model(s) you downloaded
+  listed in the JSON response.

- clone LocalAI
- get the model
- copy the prompt template
- start docker
-    - -> the server will be listening on `localhost:8080`
-    - verify it works by going to [http://localhost:8080/v1/models](http://localhost:8080/v1/models) on
-      your browser and seeing listed the model you downloaded
-
-### Integrating LocalAI with big-AGI
+### Integration: chat with LocalAI

 - Go to Models > Add a model source of type: **LocalAI**
- Enter the address: `http://localhost:8080` (default)
-    - If running remotely, replace localhost with the IP of the machine. Make sure to use the **IP:Port** format

+
+## Code Alterations
+
+Start by creating a fork of the [big-AGI repository](https://github.com/enricoros/big-AGI) on GitHub for a personal development space.
+Understand the Architecture: big-AGI uses Next.js, React for the front end, and Node.js (Next.js edge functions) for the back end.
+
+### Add Authentication
+
+This necessitates a code change (file renaming) before build initiation, detailed in [deploy-authentication.md](deploy-authentication.md).
+
+### Change the Personas
+
+Edit the `src/data.ts` file to customize personas. This file houses the default personas. You can add, remove, or modify these to meet your project's needs.
+
+- [ ] Modify `src/data.ts` to alter default personas
+
+### Change the UI
+
+Adapt the UI to match your project's aesthetic, incorporate new features, or exclude unnecessary ones.
+
+- [ ] Adjust `src/common/app.theme.ts` for theme changes: colors, spacing, button appearance, animations, etc
+- [ ] Modify `src/common/app.config.tsx` to alter the application's name
+- [ ] Update `src/common/app.nav.tsx` to revise the navigation bar
+
+## Testing & Deployment
+
+Test your application thoroughly using local development (refer to README.md for local build instructions). Deploy using your preferred hosting service. big-AGI supports deployment on platforms like Vercel, Docker, or any Node.js-compatible service, especially those supporting NextJS's "Edge Runtime."

+
+## Debugging
+
+We introduced the `/info/debug` page that provides a detailed overview of the application's environment, including the API keys, environment variables, and other configuration settings.

+
+## Community Projects - Share Your Project
+
+After deployment, share your project with the community. We will link to your project to help others discover and learn from your work.

+# big-AGI Analytics
+
+The open-source big-AGI project provides support for the following analytics services:
+
+- **Vercel Analytics**: automatic when deployed to Vercel
+- **Google Analytics 4**: manual setup required
+
+The following is a quick overview of the Analytics options for the deployers of this open-source project.
+big-AGI is deployed to many large-scale and enterprise though various ways (custom builds, Docker, Vercel, Cloudflare, etc.),
+and this guide is for its customization.
+
+## Service Configuration
+
+### Vercel Analytics
+
+- Why: understand coarse traction, and identify deployment issues - all without tracking individual users
+- What: top pages, top referrers, country of origin, operating system, browser, and page speed metrics
+
+Vercel Analytics and Speed Insights are local API endpoints deployed to your domain, so everything stays within your
+domain. Furthermore, the Vercel Analytics service is privacy-friendly, and does not track individual users.
+
+This service is avaialble to system administrators when deploying to Vercel. It is automatically enabled when deploying to Vercel.
+The code that activates Vercel Analytics is located in the `src/pages/_app.tsx` file:
+
+```tsx
+const MyApp = ({ Component, emotionCache, pageProps }: MyAppProps) => <>
+  ...
+  {isVercelFromFrontend && <VercelAnalytics debug={false} />}
+  {isVercelFromFrontend && <VercelSpeedInsights debug={false} sampleRate={1 / 2} />}
+  ...
+</>;
+```
+
+When big-AGI is served on Vercel hosts, the ```process.env.NEXT_PUBLIC_VERCEL_URL``` environment variable is trueish, and
+analytics will be sent by default to the Vercel Analytics service which is deployed by Vercel IF configured from the
+Vercel project dashboard.
+
+In summary: to turn it on: activate the `Analytics` service in the Vercel project dashboard.
+
+### Google Analytics 4
+
+- Why: user engagement and retention, performance insights, personalization, content optimization
+- What: https://support.google.com/analytics/answer/11593727
+
+Google Analytics 4 (GA4) is a powerful tool for understanding user behavior and engagement.
+This can help optimize big-AGI, understanding which features are needed/users and which aren't.
+
+To enable Google Analytics 4, you need to set the `NEXT_PUBLIC_GA4_MEASUREMENT_ID` environment variable
+before starting the local build or the docker build (i.e. at build time), at which point the
+server/container will be able to report analytics to your Google Analytics 4 property.
+
+As of Feb 27, 2024, this feature is in development.
