 # Configuring Environment Variables
 
-Eclipse configures automatically the required environment variables in the `Preferences` > `C/C++ Build` > `Environment` section if IDF Tools are installed using `Espressif` > `ESP-IDF Tools Manager` > `Install Tools` menu option. Required environment variables:
-
-* `IDF_PATH`
-* `PATH`
-* `OPENOCD_SCRIPTS`
-* `IDF_PYTHON_ENV_PATH`
-
-If the required environment variables are not configured for any reason, please follow the step-by-step instructions below.
-
-1. Click on the `Environment` preference page under `C/C++ Build`.
-1. Click `Add…` again, and enter name `IDF_PATH`. The value should be the full path where ESP-IDF is installed.
-1. Similarly, we should configure `OPENOCD_SCRIPTS`, `IDF_PYTHON_ENV_PATH` and `PATH` environment variables.
