+Localization
+============
+
+Unless you a native English speaker, you may like to run Micropolis
+in your own language. Micropolis is designed to be run in any language,
+but we need translators to provide the translated text to display.
+
+ 1. Open a command prompt window and `cd' to the directory containing
+    the micropolisj.jar file.
+
+ 2. Run the following command to launch the translation tool:
+
+    java -cp micropolisj.jar micropolisj.util.TranslationTool
+
+ 3. Click Add Locale and enter the appropriate 2-character language
+    code, and (optionally) a 2-character country code.
+
+ 4. Next to each string, double-click the blank field and type in
+    a translation.
+
+ 5. Click Save. (This will cause the translated strings to be written
+    in the proper format into a subdirectory named micropolisj.)
+
+ 6. Close the translation tool. Send the generated files (from the
+    micropolisj subdirectory) to jason@long.name for inclusion in the
+    next release of Micropolis.
