To host a website using your ESP-WROOM-32 module and a microSD card, you can follow these general steps:

```
ESP-WROOM-32 MicroSD Card Module
| |
| CS (GPIO X) ---------------------| CS
| SCK (GPIO Y) --------------------| SCK
| MOSI (GPIO Z) -------------------| MOSI
| MISO (GPIO W) -------------------| MISO
| 3.3V ----------------------------| VCC (or 3.3V)
| GND -----------------------------| GND
```
