### 3.1 Working with DITA2Go configuration files

To add or change conversion settings after you set up a DITA2Go project, you must edit the contents of one or more configuration files: text files with file extension .ini.

You will need two tools to work effectively with DITA2Go configuration files:

- The DITA2Go Configuration Manager, to see and manipulate individual sections and settings selected from all relevant configuration files and system templates that apply to your project; see §3.2 Editing files with the Configuration Manager
- A text editor (even Notepad) to inspect and optionally edit all sections and settings in individual configuration files:
  - Make sure you use only ANSI, or UTF-8, encoding; do not use UTF-16 for configuration files.
  - Do not use Word, or any other application that gets an exclusive-write lock on files.

You might find it useful to have both tools open at once, so you can readily see in context, in the text editor, any changes you make with the Configuration Manager.
