+## Using Command-Line Options
+
 It is possible to install Git for Windows silently using the following flags when called from a command-line prompt:
+
 ```
 Git-<version>-<bitness>.exe /VERYSILENT /NORESTART /NOCANCEL /SP- /CLOSEAPPLICATIONS /RESTARTAPPLICATIONS /COMPONENTS="icons,ext\reg\shellhere,assoc,assoc_sh"
 ```
 
-An example of this is
+## Using Installer Options From a File
+
+You can also load install parameters from a file with `/LOADINF="filename"`, and you can record parameters to a file using `/SAVEINF="filename"`.
+
+Example for saving selected options to a file:
+
 ```
-Git-2.12.2.2-64-bit.exe  /VERYSILENT /NORESTART /NOCANCEL /SP- /CLOSEAPPLICATIONS /RESTARTAPPLICATIONS /COMPONENTS="icons,ext\reg\shellhere,assoc,assoc_sh"
+Git-<version>-<bitness>.exe /SAVEINF=git_options.ini
 ```
 
-You can find all of the possible flags to use by calling the installer with the `/?` flag (for the options supported by InnoSetup out of the box), and by inspecting the [`install.iss` file](https://github.com/git-for-windows/build-extra/blob/HEAD/installer/install.iss) (for custom options added only to Git for Windows' installer).
+Example reusing that previously created file to silently install Git in unattended mode:
 
-You can also load install parameters from a file with `/LOADINF="filename"`, and you can record parameters to a file using `/SAVEINF="filename"`.
+```
+Git-<version>-<bitness>.exe /VERYSILENT /NORESTART /NOCANCEL /LOADINF=git_options.ini
+```
 
 An example of a parameter file is:
 
-```
+```ini

 Dir=C:\Program Files\Git
