+## Troubleshooting
+
+This section provides guidance on how to resolve potential errors and unexpected behavior when running the tutorial.
+
+### Docker compose errors
+If you receive unexpected errors when running `docker compose up`, or do not get healthy containers, you can try recreating the tutorial Docker containers using the `--force-recreate` argument.
+```
+docker compose up --build --force-recreate --detach --wait
+```
+
+### GX Cloud environment variables warning
+The tutorial Docker compose is defined to capture `GX_CLOUD_ORGANIZATION_ID` and `GX_CLOUD_ACCESS_TOKEN` environment variables to support Cookbook 3. If these variables are not provided when running `docker compose up`, you will see the following warnings:
+
+```
+WARN[0000] The "GX_CLOUD_ORGANIZATION_ID" variable is not set. Defaulting to a blank string.
+WARN[0000] The "GX_CLOUD_ACCESS_TOKEN" variable is not set. Defaulting to a blank string.
+WARN[0000] The "GX_CLOUD_ORGANIZATION_ID" variable is not set. Defaulting to a blank string.
+WARN[0000] The "GX_CLOUD_ACCESS_TOKEN" variable is not set. Defaulting to a blank string.
+```
+
+You can safely ignore the these warnings if:
+* You are not trying to run Cookbook 3.
+* You are running `docker compose down --volumes` to stop the running Docker compose.
