 ## v0.2
 ### v0.2.13 (2021-???)
 #### Features
+- Added `-v`/`--verbose` flag for setting verbosity without using `RUST_LOG`
 - Added system extension set (`.dll`, `.so`, `.exe`...)
 - Output is now sorted: Files that couldn't be read, then files with no known mimetype, then files with no known
   extensions, then files with the wrong extension

 ## Usage
 See `fif --help` for more.
 
-### Logging
-By default, fif will log any warnings and/or errors encountered during execution. The verbosity of the logging can be
-modified by the `RUST_LOG` to one of: `trace`, `debug`, `info`, `warn`, `error`.

-For example:

+### Logging
+By default, fif will log any warnings and/or errors encountered during execution. This can be changed with the `-v`

+The verbosity of the logging can be

+
+For example:
+
+```bash

+
+The five logging levels are used as follows:
+| Level | Description | Example |
+|-|-|-|
+| error | Errors that cause fif to stop running | fif was unable to open the provided directory |
+| warn | Warnings that don't cause fif to stop running | fif was unable to determine the mime type of a given file |
+| info | Information pertaining to fif's status | The provided directory was scanned without issue, and no files are in need of renaming |
+| debug | Debug information - usually not important to end users | The list of extensions fif will consider |
+| trace | Trace info - usually not important to end users | "Found 15 items to check", "Scan successful", etc. |
