 ## Dependencies
 
-The [Arduino IDE](https://github.com/arduino/arduino-ide) must be installed.
+Install the [ESP-IDF](https://github.com/espressif/esp-idf?tab=readme-ov-file#setup-build-environment)
-
- install [ESP-IDF](https://github.com/espressif/esp-idf?tab=readme-ov-file#setup-build-environment)
 
 ```bash
-git clone -b v5.3.2 git@github.com:espressif/esp-idf.git
+# https://docs.espressif.com/projects/esp-idf/en/v5.3.2/esp32/get-started/linux-macos-setup.html#for-linux-users
+sudo apt-get install -y git wget flex bison gperf python3 python3-pip python3-venv cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0
+
+git clone -b v5.3.2 --recursive https://github.com/espressif/esp-idf
 cd esp-idf
 ./install.sh
-
-# You only need to do this if you want to use ESP-IDF's idf.py helper script.
-# This example uses cmake, so it's not required.
 . ./export.sh
 ```
 
+In CLion there is an official [Serial Monitor](https://plugins.jetbrains.com/plugin/8031-serial-port-monitor) plugin, or use ESP-IDF -
 
+```bash
+idf.py monitor -b 115200
+```
+
+## Starting Over
+
+To set up this project from scratch the following commands were used
+
+```bash
+# My example project directory
+cd ~/Code/klips/esp/cpp/04_esp-idf-arduino
+idf.py set-target esp32
+idf.py add-dependency "espressif/arduino-esp32^3.1.1"
+
+# Autostart Arduino for use of `loop()` and `setup()` functions
+# You can also use the esp-idf `app_main()` function if preferred
+# https://docs.espressif.com/projects/arduino-esp32/en/latest/esp-idf_component.html#configuration
+# You can alternatively do this in the GUI tool `idf.py menuconfig`
+echo "CONFIG_AUTOSTART_ARDUINO=y" >> sdkconfig
+sed -i -e 's/CONFIG_FREERTOS_HZ=100/CONFIG_FREERTOS_HZ=1000/' sdkconfig
+
+# Build the project
+idf.py build
+```
+
+To set this project up in CLion, see [JetBrains documentation](https://www.jetbrains.com/help/clion/esp-idf.html#env-vars).

+# 05_temp-humidity-web
+
+This is the same example in [03_temp-humidity-web](./../03_temp-humidity-web), ported to the cmake ESP-IDF build system.
+
+For instructions on setting up the ESP-IDF see [04_-esp-idf-arduino](./../04_esp-idf-arduino)
+
+This example is largely adapted from those in [ESP32-basic-starter-kit.pdf](./ESP32-basic-starter-kit.pdf).
+
+The APIs in the original examples paired with this PDF have changed, and I decided to do some different things with the code and/or circuits, but the original code can be [found here](https://www.dropbox.com/scl/fo/6znlij3eb23ih4jxcpv2w/AKvB1t9CCUgoVRVtGen8Yrw?rlkey=z84anl0hs940qf9fpl7l8q8q2&e=1&dl=0).
+
+![schematic](./schematic.png)
+
+Temperature and humidity sensor served on a web page within the local network.
+
+![screenshot](./screenshot.png)
+
+To build this example run the following commands.
+
+```bash
+source ~/path/to/esp-idf/export.sh
+
+mkdir build
+cd build
+cmake ..
+make -j $(nproc)
+make flash
+```

-This directory contains ESP32 projects largely adapted from the examples in [ESP32-basic-starter-kit.pdf](./ESP32-basic-starter-kit.pdf).
+Examples 1-3 are built using the Arduino IDE.
 
-The APIs in the original examples paired with this PDF have changed, and I decided to do some different things with the code and/or circuits, but the original code can be [found here](https://www.dropbox.com/scl/fo/6znlij3eb23ih4jxcpv2w/AKvB1t9CCUgoVRVtGen8Yrw?rlkey=z84anl0hs940qf9fpl7l8q8q2&e=1&dl=0).
+All examples after `04_esp-idf-arduino` are built with cmake and the [ESP-IDF](https://github.com/espressif/esp-idf).
