Example verification commands

SHA256:
```
sha256sum os-name-version.iso
```

GPG signature verification:

gpg --verify os-name-version.iso.sig os-name-version.iso

Read the README or .txt files – Many directories include checksums (MD5/SHA256), release notes, or update instructions.

A parent directory index is a server-generated list of files and subdirectories. Instead of a polished webpage, you see a raw file list—usually titled "Index of /"—that allows you to navigate the server's hierarchy. This is where you can find:
