+Letter blocks can be created with the Letter Machine or given with /giveme ehlphabet:(ascii decimal)
+
+Example: `/giveme ehlphabet:65` will give you a block with the letter [**A**] on it.
+http://www.asciitable.com/
+
+For UTF-8 characters add one more identifier /giveme ehlphabet:(first byte decimal)_(second byle decimal)
+
+Example: `/giveme ehlphabet:195_132` will give you a block with the letter [**Ä**] on it.

+
+## Textures
+
+Textures were generated using [**phantomjs**](http://phantomjs.org/download.html) script "gen.js" included in this repository.
+
+To (re)generate textures run:
+
+    $ phantomjs gen.js
+
+To customize the look and size of letters, you need to know basic HTML and CSS and change it inside "gen.js".
