+In this example, write your credentials to environment variables on the local machine that runs the application.
+
+[!INCLUDE [find key and endpoint](./find-key.md)]
+
+> [!TIP]
+> Don't include the key directly in your code, and never post it publicly. See the Azure AI services [security](../../security-features.md) article for more authentication options like [Azure Key Vault](../../use-key-vault.md).
+
+To set the environment variable for your key and endpoint, open a console window and follow the instructions for your operating system and development environment.
+
+1. To set the `VISION_KEY` environment variable, replace `your-key` with one of the keys for your resource.
+2. To set the `VISION_ENDPOINT` environment variable, replace `your-endpoint` with the endpoint for your resource.
+
+#### [Windows](#tab/windows)
+
+```console
+setx VISION_KEY your-key
+```
+
+```console
+setx VISION_ENDPOINT your-endpoint
+```
+
+After you add the environment variables, you may need to restart any running programs that will read the environment variables, including the console window.
+
+#### [Linux](#tab/linux)
+
+```bash
+export VISION_KEY=your-key
+```
+
+```bash
+export VISION_ENDPOINT=your-endpoint
+```
+
+After you add the environment variables, run `source ~/.bashrc` from your console window to make the changes effective.
