 Translations
 ============
 
 Texts can be translated client-side with the help of `minetest.translate` and
 translation files.
 
+Consider using the tool [update_translations](https://github.com/minetest-tools/update_translations)
+to generate and update translation files automatically from the Lua source.

 Translating a string

   It is intended to be used in the following way, so that it avoids verbose

   As an extra commodity, if `textdomain` is nil, it is assumed to be "" instead.

   For instance, suppose we want to translate "@1 Wool" with "@1" being replaced
   by the translation of "Red". We can do the following:
 
-      local S, NS = minetest.get_translator()
-      S("@1 Wool", S("Red"))
+  ```lua
+  local S, NS = minetest.get_translator()
+  S("@1 Wool", S("Red"))

   This will be displayed as "Red Wool" on old clients and on clients that do
   not have localization enabled. However, if we have for instance a translation
   file named `wool.fr.tr` containing the following:
 
-      @1 Wool=Laine @1
-      Red=Rouge
+  ```
+  @1 Wool=Laine @1
+  Red=Rouge

   this will be displayed as "Laine Rouge" on clients with a French locale.
