You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b HEAD is now at 4f5689f Merge branch 'ci/add_push_to_github' into 'master' [rtd-command-info] start-time: 2020-12-08T04:07:47.043815Z, end-time: 2020-12-08T04:07:47.102674Z, duration: 0, exit-code: 0 git clean -d -f -f [rtd-command-info] start-time: 2020-12-08T04:07:47.828289Z, end-time: 2020-12-08T04:07:48.400835Z, duration: 0, exit-code: 0 git submodule sync [rtd-command-info] start-time: 2020-12-08T04:07:48.505225Z, end-time: 2020-12-08T04:08:07.483108Z, duration: 18, exit-code: 1 git submodule update --init --force --recursive submodule/esp-idf components/network/mqtt/espmqtt components/platforms/alink/esp32-alink components/spi_devices/lcd/Adafruit-GFX-Library components/hmi/ugfx_gui/ugfx components/hmi/lvgl_gui/lvgl Submodule 'components/hmi/lvgl_gui/lvgl' (https://github.com/littlevgl/lvgl.git) registered for path 'components/hmi/lvgl_gui/lvgl' Submodule 'components/hmi/ugfx_gui/ugfx' (https://git.ugfx.io/ugfx/ugfx.git) registered for path 'components/hmi/ugfx_gui/ugfx' Submodule 'components/network/mqtt/espmqtt' (https://github.com/tuanpmt/espmqtt.git) registered for path 'components/network/mqtt/espmqtt' Submodule 'components/platforms/alink/esp32-alink' (https://github.com/espressif/esp32-alink.git) registered for path 'components/platforms/alink/esp32-alink' Submodule 'Adafruit-GFX-Library' (https://github.com/adafruit/Adafruit-GFX-Library.git) registered for path 'components/spi_devices/lcd/Adafruit-GFX-Library' Submodule 'submodule/esp-idf' (https://github.com/espressif/esp-idf.git) registered for path 'submodule/esp-idf' Cloning into '/home/docs/checkouts/readthedocs.org/user_builds/espressif-esp-iot-solution/checkouts/latest/components/hmi/lvgl_gui/lvgl'...
