1. some links have a backslash in their paths

2. Section "For ESP-A1s (ESP32 + AC101 audio chips)"

es8388 instead of ac101:

and later
laster , add the below code to edit the CMake file : components/audio_hal/CMakeLists.txt

./driver/es8388
./driver/es8388/es8388.c

and an image is missing/wrong syntax:
![](static/add_ac101_cmake files.png)

... and I had to remove all non-ac101 (es8388, ..) lines from components/audio_hal/CMakeLists.txt
because of errors like

esp-adf/components/audio_hal/driver/es8311/es8311.c:59:22: error: 'BOARD_PA_GAIN' undeclared (first use in this function)

ok #38 (comment) instead is enough, no need to remove non-ac101 from CMakeLists.txt

https://github.com/Ai-Thinker-Open/ESP32-A1S-AudioKit/blob/master/static/add_ac101_cmake%20files.png does contain es8388 instead of ac101, too
