 ### Rotary Encoder
-One general 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. A bit of filtering on A and B (~470nF) helps for debouncing which is not made by software.

-Encoder is normally hard-coded to respectively knob left, right and push on LMS and to volume down/up/play toggle on BT, AirPlay and Spotify. Using the option 'volume' makes it hard-coded to volume down/up/play toggle all the time (even in LMS). The option 'longpress' allows an alternate mode when SW is long-pressed. In that mode, left is previous, right is next and press is toggle. Every long press on SW alternates between modes (the main mode actual behavior depends on 'volume').

 There is also the possibility to use 'knobonly' option (exclusive with 'volume' and 'longpress').

 ### Manual Install of ESP-IDF
-First you need git and python (e.g 3.10.x), install these and let it add to system path.
+You can install IDF manually on Linux or Windows (using the Subsystem for Linux) following the instructions at: https://www.instructables.com/id/ESP32-Development-on-Windows-Subsystem-for-Linux/ or see here https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/windows-setup.html for a direct install. You also need a few extra Python libraries for cspot by addingsudo `pip3 install protobuf grpcio-tools`
+

You should clone recursively the whole branch (at the version you need) `git clone -b v4.3.5 https://github.com/espressif/esp-idf --recursive`and run the installer (`install.bat [esp32[,esp32s3]]` from there. Some Windows version (at least) have now a SSL certificate issue. You can workaround this by editing idf-tools.py and adding the following under ìmport ssl`
-```
-import ssl
-ssl._create_default_https_context = ssl._create_unverified_context
-```
-And because the fun never ends, some Windows installations might fail to build a few files and spit a tons of errors on the output. It seems that the cache of the compile is a problem, so try to disable it by running `idf.py --no-ccache build` (I know...)
 ## Building SqueezeESP32
-When initially cloning the repo, make sure you do it recursively. For example: `git clone --recursive https://github.com/sle118/squeezelite-esp32.git`. You also should install cspot additional components for protobuf use.
-```
-$ sudo pip3 install protobuf grpcio-tools
-```
-NB: I need to check on a fresh installation, but you might also require "protoc". You should do that within the esp32 local Python environment.
+When initially cloning the repo, make sure you do it recursively. For example: `git clone --recursive https://github.com/sle118/squeezelite-esp32.git`
 	
 Don't forget to choose one of the config files in build_scripts/ and rename it sdkconfig.defaults or sdkconfig as many important WiFi/BT options are set there. **The codecs libraries will not be rebuilt by these scripts (it's a tedious process - see below)**
