+# ESP32 Wi-Fi Connect
+
+This component helps with Wi-Fi connection for the device.
+
+It first tries to connect to a Wi-Fi network using the credentials stored in the flash. If this fails, it starts an access point and a web server to allow the user to connect to a Wi-Fi network.
+
+The URL to access the web server is `http://192.168.4.1`.

+## Configuration
+
+The Wi-Fi credentials are stored in the flash under the "wifi" namespace.
+
+The keys are "ssid", "ssid1", "ssid2" ... "ssid9", "password", "password1", "password2" ... "password9".
+
+## Usage
+
+```cpp
+// Initialize the default event loop
+ESP_ERROR_CHECK(esp_event_loop_create_default());
+
+// Initialize NVS flash for Wi-Fi configuration
+esp_err_t ret = nvs_flash_init();
+if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
+    ESP_ERROR_CHECK(nvs_flash_erase());
+    ret = nvs_flash_init();
+}
+ESP_ERROR_CHECK(ret);
+
+// Get the Wi-Fi configuration
+auto& ssid_list = SsidManager::GetInstance().GetSsidList();
+if (ssid_list.empty()) {
+    // Start the Wi-Fi configuration AP
+    auto& ap = WifiConfigurationAp::GetInstance();
+    ap.SetSsidPrefix("ESP32");
+    ap.Start();
+    return;
+}
+
+// Otherwise, connect to the Wi-Fi network
+WifiStation::GetInstance().Start();
+```
