+
+The generate-license-file CLI can be configured using a config file so that you don't need to re-enter the same
+config options every time. The config file also allows you to specify additional more complex options that are not
+available as CLI flags.
+
+## File Formats
+
+Config files can be called either `.glf` or `.generatelicensefile` and can be customised using the following options:
+
+- File name can optionally end with `rc`
+- Can be in a `./.config` directory (no longer needs the `.` prefix on the file name)
+- Have the following file extensions: `.json`, `jsonc`, `.json5`, `.yaml`, `.yml`, `.js`, `.cjs`
+
+E.g. `.glf.json`, `.glfrc.yml`, `.generatelicensefile.jsonc`, `.config/glf.js`, and more.
+
+## Config Options
+
+The file can contain all of the options that are [available as CLI flags](./).

+
+#### Replace
+
+The replace option allows you to replace the license content for a specific dependency. This is useful in situations like:
+
+- A dependency does not have its license file included in the published package
+- The license file is not in a standard format
+- The published package contains multiple license files and you want to pick a specific one
+
+Packages can be specified using the format `package@version` or `package`, where the latter will match all versions of a given package. If both are specified, then the configuration with a matching version will take precedence.
+
+:::info
+
+While it might be more convenient to use the package name without the version, it is recommended to use the version where possible to guarantee you always know exactly which package you are replacing the license for.
+
+:::
+
+The replacement value can be:
+
+- A relative or absolute file path to a location on disk
+- A URL to a remote file on the internet
+
+:::tip
+
+An advantage to using a file path over a URL is that the generated output will always be the same for any given commit.

+## File Location
+
+If you want to keep your config file in a different location to the current working directory (or a `./.config` directory)
+then you can specify the location of the config file using the `--config` CLI flag.
+
+```bash
+generate-license-file --config ./path/to/config.json
+```
