 - collections are stored in a local persistent Chroma database in the current directory
 - `import` requires the target collection to already exist
-- the CLI prints friendly messages for common errors such as missing collections or missing files
+- `import` accepts one or more file paths
+- unquoted glob patterns such as `*.md` are expanded by the shell before `chromy` starts
+- quoted glob patterns such as `"*.md"` are treated as literal paths and are not expanded by `chromy`
+- unmatched unquoted globs may behave differently by shell: `zsh` commonly fails before `chromy` starts, while `bash` may pass the literal pattern through depending on shell settings
+- the CLI reports file-specific import failures and continues with the remaining files
