+# AtomVM emulator/simulator tests
+
+AtomVM provides two paths for testing "on device", the locally run QEMU emulator or the remote Wokwi CI simulator.
+
+# QEMU emulator testing
+
+Instructions for running the tests [on QEMU are documented here](https://www.atomvm.net/doc/main/build-instructions.html#running-tests-for-esp32).
+
+# Wokwi CI simulator testing
+
+Wokwi CI is a commercial cloud CI, see [wokwi-ci/getting-started](https://docs.wokwi.com/wokwi-ci/getting-started), running it locally requires you to obtain a `WOKWI_CLI_TOKEN` [Get token](https://wokwi.com/dashboard/ci) and usage fees may apply in the future - AtomVM uses it through the [pytest-embedded-wokwi](https://github.com/espressif/pytest-embedded/tree/main/pytest-embedded-wokwi) integration.
+
+## Github CI/Actions
+
+The `WOKWI_CLI_TOKEN` needs to be set in your `Repository secrets` Settings -> Actions secrets and variables.
+
+## Installing prerequisites
+
+1. The Wokwi CLI needs to be installed:
+
+   ```shell
+   curl -L https://wokwi.com/ci/install.sh | sh
+   ```
+
+   Or [alternative installation methods here](https://docs.wokwi.com/wokwi-ci/getting-started#cli-installation).
+
+2. `WOKWI_CLI_TOKEN` needs to be set in your enviroment variables:
+
+   ```shell
+   export WOKWI_CLI_TOKEN="your-api-key"
+   ```
+
+3. A recent pytest, and pytest-embedded must be installed:
+
+   ```shell
+   $ pip install pytest==8.3.3 \
+   pytest-embedded==1.11.5 \
+   pytest-embedded-serial-esp==1.11.5 \
+   pytest-embedded-idf==1.11.5 \
+   pytest-embedded-wokwi==1.11.5
+   ```
+
+4. The ESP-IDF build environment must be installed and available:
+
+   ```shell
+   get_idf
+   ```
+
+## Compiling for and running Wokwi CI
+
+1. We need to use a special sdkconfig (`sdkconfig.ci.wokwi`) different from the QEMU one. So we set `IDF_TARGET`, and run `idf.py -DSDKCONFIG_DEFAULTS=sdkconfig.ci.wokwi set-target ${IDF_TARGET}`:
+
+   ```shell
+   export IDF_TARGET=esp32 && idf.py -DSDKCONFIG_DEFAULTS=sdkconfig.ci.wokwi set-target ${IDF_TARGET}
+   ```
+
+2. Wokwi CI uses a `diagram.json`, to describe the device used (specific board, pin connections, sensors, sd card etc). 'diagram.json' files are available for each target in the sim_boards folder.
+
+3. Now we run `idf.py build` and run the CI:
+
+   ```shell
+   idf.py build -DSDKCONFIG_DEFAULTS='sdkconfig.ci.wokwi' && pytest -k 'test_atomvm_sim' --embedded-services=idf,wokwi --wokwi-timeout=90000 --target=${IDF_TARGET} --wokwi-diagram=sim_boards/diagram.${IDF_TARGET}.json -s -W ignore::DeprecationWarning
+   ```
