+## Troubleshooting and Known Issues
 
-If you encounter unexpected behavior or a bug, please [file an issue](https://github.com/nickgerace/gfold/issues) and debug
-locally with `RUST_BACKTRACE=1 RUST_LOG=debug` prepended when executing `gfold`.
-You can also adjust each variable, as needed, to aid investigation.
-Please attach relevant logs from execution with sensitive bits redacted in order to help resolve your issue.
+If you encounter unexpected behavior or a bug and would like to see more details, please run `gfold` with the following

+[`RUST_LOG`](https://docs.rs/env_logger/latest/env_logger/), do not have `gfold`-specific behaviors, you can adjust
