-## Options
+## Configuration
+
+`qrcp` works without any prior configuration, however, you can choose to configure to use specific values.
+
+To configure `qrcp` you can create a configuration file inside `$XDG_CONFIG_HOME/qrcp`.
+
+> Note: On Linux, the `$XDG_CONFIG_HOME` is `.config` under user home directory.
+> So, for example, on Linux the configuration file will be `$HOME/.config/qrcp/config.yml`.
+
+> Note: Starting from version 0.10.0, qrcp uses a YAML configuration file instead of the old JSON one. You can automatically migrate the legacy JSON format to the new YAML format by running `qrcp config migrate`.
+
+| Key         | Type    | Notes                                                                                                                                                                                  |
+|-------------|---------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `interface` | String  | This value is automatically discovered during the first launch of `qrcp`, you can set it to override the default. You can use the `any` interface to bind the web server to `0.0.0.0`. |
+| `bind`      | String  | This value is used by qrcp to bind the web server to. Note: if this value is set, the `interface` parameter is ignored.                                                                |
+| `port`      | Integer | When this value is not set, `qrcp` will pick a random port at any launch.                                                                                                              |
+| `path`      | String  | When this value is not set, `qrcp` will add a random string at the end of URL.                                                                                                         |
+| `output`    | String  | Default directory to receive files to. If empty, the current working directory is used.                                                                                                |
+| `fqdn`      | String  | When this value is set, `qrcp` will use it to replace the IP address in the generated URL.                                                                                             |
+| `keepAlive` | Bool    | Controls whether `qrcp` should quit after transferring the file. Defaults to `false`.                                                                                                  |
+| `secure`    | Bool    | Controls whether `qrcp` should use HTTPS instead of HTTP. Defaults to `false`                                                                                                          |
+| `tls-cert`  | String  | Path to the TLS certificate. It's only used when `secure: true`.                                                                                                                       |
