 One rotary encoder is supported, quadrature shift with press. Such encoders usually have 2 pins for encoders (A and B), and common C that must be set to ground and an optional SW pin for press. A, B and SW must be pulled up, so automatic pull-up is provided by ESP32, but you can add your own resistors.

+# Configuration
+## Setup WiFi
+- Boot the esp, look for a new wifi access point showing up and connect to it. Default build ssid and passwords are "squeezelite"/"squeezelite". 
+- Once connected, navigate to 192.168.4.1 
+- Wait for the list of access points visible from the device to populate in the web page.
+- Choose an access point and enter any credential as needed
+- Once connection is established, note down the address the device received; this is the address you will use to configure it going forward 
+
+## Setup squeezelite command line (optional)
+
+At this point, the device should have disabled its built-in access point and should be connected to a known WiFi network.
+- navigate to the address that was noted in step #1
+- Using the list of predefined options, choose the mode in which you want squeezelite to start
+- Generate the command
+- Add or change any additional command line option (for example player name, etc)
+- Activate squeezelite execution: this tells the device to automatiaclly run the command at start
+- Update the configuration
+- click on the "start toggle" button. This will force a reboot. 
+- The toggle switch should be set to 'ON' to ensure that squeezelite is active after booting (you might have to fiddle with it a few times)
+- You can enable accessto  NVS parameters under 'credits'
+
+## Monitor
+
+In addition of the esp-idf serial link monitor option, you can also enable a telnet server (see NVS parameters) where you'll have access to a ton of logs of what's happening inside the WROVER.
+
+## Update Squeezelite
+- From the firmware tab, click on "Check for Updates"
+- Look for updated binaries
+- Select a line
+- Click on "Flash!"
+- The system will reboot into recovery mode (if not already in that mode), wipe the squeezelite partition and download/flash the selected version 
+- You can choose a local file or have a local webserver
+
+## Recovery
+- From the firmware tab, click on the "Recovery" button. This will reboot the ESP32 into recovery, where additional configuration options are available from the NVS editor
+
+## Additional configuration notes (from the Web UI)
+The squeezelite options are very similar to the regular Linux ones. Differences are :
+
+	- the output is -o ["BT -n '<sinkname>' "] | [I2S]
+	- if you've compiled with RESAMPLE option, normal soxr options are available using -R [-u <options>]. Note that anything above LQ or MQ will overload the CPU
+	- if you've used RESAMPLE16, <options> are (b|l|m)[:i], with b = basic linear interpolation, l = 13 taps, m = 21 taps, i = interpolate filter coefficients
+
+For example, so use a BT speaker named MySpeaker, accept audio up to 192kHz and resample everything to 44100 and use 16 bits resample with medium quality, the command line is:
+	
+	squeezelite -o "BT -n 'BT <sinkname>'" -b 500:2000 -R -u m -Z 192000 -r "44100-44100"
+
+See squeezlite command line, but keys options are
+
+	- Z <rate> : tell LMS what is the max sample rate supported before LMS resamples
+	- R (see above)
+	- r "<minrate>-<maxrate>"
+	- C <sec> : set timeout to switch off amp gpio
+	- W : activate WAV and AIFF header parsing

+Use 'idf monitor' to monitor the application (see esp-idf documentation)
+## Additional misc notes to do you build (kitchen sink)
 - as of this writing, ESP-IDF has a bug int he way the PLL values are calculated for i2s, so you *must* use the i2s.c file in the patch directory
 - for codecs libraries, add -mlongcalls if you want to rebuild them, but you should not (use the provided ones in codecs/lib). if you really want to rebuild them, open an issue
