 # Arduino Sony RM-D27M Minidisc Namer
 
 This is an arduino sketch to make an IR-remote control for easier title renaming on a Sony MDS-JE510 minidisc deck.
+
+- Add webserver
+- Add ir remote library
+- Add SD-Card support to load html and css
+
+Store WiFi secrets in a secrets.h like this:
+
+```c
+#define SSID      "your-ssid"
+#define PASSWORD  "your-password"
+```
+
+## Circuit
+
+Circuit:
+
+- LED attached to pin 13 (optional)
+- IR Transmitter attached to pin 4 (connect to 5v or 3v3)
+- SD-Module to load HTML and CSS from SD-card
+
+Connect the SD card to the following pins:
+
+SD Card | ESP32
+------- | -----
+3v3     | 3.3V
+CS      | 5
+MOSI    | 23
+CLK     | 18
+MISO    | 19
+GND     | GND
