<!-- Greeting --> Hi @bettermultiply! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the opendal team. <!-- Answer --> You're absolutely right—many new users run into similar issues with the examples, especially around the .env setup and directory permissions. The "Permission denied (os error 13)" error usually means the process doesn't have write access to the directory specified by environment variables like OPENDAL_FS_ROOT or atomic_write_dir, or that the directory doesn't exist yet. This is a common stumbling block and has come up in several user reports and issues before ([example](https://github.com/apache/opendal/issues/5781), [example](https://github.com/apache/opendal/issues/5639), [example](https://github.com/apache/opendal/issues/4867)). To make the README more newbie-friendly, it would help to: - Add step-by-step instructions for copying and editing the .env file, including which variables must be set for each example. - Explicitly mention that directories like OPENDAL_FS_ROOT and atomic_write_dir must exist and be writable by the user running the example. - Include a troubleshooting section for common errors like "Permission denied" or "root is not specified", with tips on how to fix them (e.g., `mkdir -p /path/to/dir && chmod u+w /path/to/dir`). - Clarify that some services (like HDFS) may require extra environment variables or system configuration. Your feedback matches what others have experienced, and maintainers have discussed moving examples and improving docs to make onboarding smoother for everyone ([see here](https://github.com/apache/opendal/issues/2446)). If you have specific suggestions or wording that helped you, sharing those would be valuable for making the docs even better! <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
