+## SD Card Requirements
+
+**An SD card is essential for Meck to function properly.** Many features — including the e-book reader, notes, bookmarks, web reader cache, audiobook playback, firmware updates, contact import/export, and WiFi credential storage — rely on files stored on the SD card. Without an SD card inserted, the device will boot and handle mesh messaging, but most extended features will be unavailable or will fail silently.
+
+**Recommended:** A **32 GB or larger** microSD card formatted as **FAT32**. MeshCore users have found that **SanDisk** microSD cards are the most reliable across both the T-Deck Pro and T5S3.

 ## Flashing Firmware
 
 Download the latest firmware from the [Releases](https://github.com/pelgraine/Meck/releases) page. Each release includes two types of `.bin` files per build variant:
 
 | File Type | When to Use |
 |-----------|-------------|
-| `*_merged.bin` | **First-time flash** — includes bootloader, partition table, and firmware in a single file. Flash at address `0x0`. |
+| `*-merged.bin` | **First-time flash** — includes bootloader, partition table, and firmware in a single file. Flash at address `0x0`. |

-### SD Card Launcher
+### Launcher
 
 If you're loading firmware from an SD card via the LilyGo Launcher firmware, use the **non-merged** `.bin` file. The Launcher provides its own bootloader and only needs the application image.
 
+### OTA Firmware Update (v1.3+)
+
+Once Meck is installed, you can update firmware directly from your phone — no computer or serial cable required. The device creates a temporary WiFi access point and you upload the new `.bin` via your phone's browser.
+
+1. Download the new **non-merged** `.bin` to your phone (from GitHub Releases, Discord, etc.)
+2. On the device: **Settings → Firmware Update → Enter** (T-Deck Pro) or **tap** (T5S3)
+3. The device starts a WiFi network called `Meck-Update-XXXX` and displays connection details
+4. On your phone: connect to the `Meck-Update` WiFi network, open a browser, go to `192.168.4.1`
+5. Tap **Choose File**, select the `.bin`, tap **Upload**
+6. The device receives the file, saves to SD, verifies, flashes, and reboots
+
+The partition layout supports dual OTA slots — the old firmware remains on the inactive partition as an automatic rollback target. If the new firmware fails to boot, the ESP32 bootloader reverts to the previous working version automatically.
+
+> **Note:** Use the **non-merged** `.bin` for OTA updates. The merged binary is only needed for first-time USB flashing.
