-- Will render to `https://<DOMAIN>/blog/post/<identifier>`.
-- Files under `assets/` (where images etc. located) should be pushed to OSS.
-- For identifiers, use prefix `-` to indicate private (hidden) visibility. EX: `-hello-world`.

+## Project Structure
+
+This project is using Qwik with [QwikCity](https://qwik.dev/qwikcity/overview/). QwikCity is just an extra set of tools on top of Qwik to make it easier to build a full site, including directory-based routing, layouts, and more.

+Inside your project, you'll see the following directory structure:

+
+- `src/routes`: Provides the directory-based routing, which can include a hierarchy of `layout.tsx` layout files, and an `index.tsx` file as the page. Additionally, `index.ts` files are endpoints. Please see the [routing docs](https://qwik.dev/qwikcity/routing/overview/) for more info.
+
+- `src/components`: Recommended directory for components.
+
+- `public`: Any static assets, like images, can be placed in the public directory. Please see the [Vite public directory](https://vitejs.dev/guide/assets.html#the-public-directory) for more info.
+
+## Add Integrations and deployment
+
+Use the `npm run qwik add` command to add additional integrations. Some examples of integrations includes: Cloudflare, Netlify or Express Server, and the [Static Site Generator (SSG)](https://qwik.dev/qwikcity/guides/static-site-generation/).
+
+```shell
+npm run qwik add # or `yarn qwik add`
+```
+
+## Development
+
+Development mode uses [Vite's development server](https://vitejs.dev/). The `dev` command will server-side render (SSR) the output during development.
+
+```shell
+npm start # or `yarn start`
+```
+
+> Note: during dev mode, Vite may request a significant number of `.js` files. This does not represent a Qwik production build.
+
+## Preview
+
+The preview command will create a production build of the client modules, a production build of `src/entry.preview.tsx`, and run a local server. The preview server is only for convenience to preview a production build locally and should not be used as a production server.
+
+```shell
+npm run preview # or `yarn preview`
+```
+
+## Production
+
+The production build will generate client and server modules by running both client and server build commands. The build command will use Typescript to run a type check on the source code.
+
+```shell
+npm run build # or `yarn build`
+```
