 There are three mastery levels
 
 1. Just build me the game:<br/>
-`sugar-qsp game.txt`<br/>
+`txt2web game.txt`<br/>
 And it will create the game in game.html
 
 2. I know what I'm doing:<br/>
-`sugar-qsp game.txt -o game.html --body body.html --js jquery.js my-js-library.js --css styles/*.css`<br/>
+`txt2web game.txt -o game.html --body body.html --js jquery.js my-js-library.js --css styles/*.css`<br/>
 All options are self-explanatory. The result is a monolithic html specified
 with the `-o` option. Default `body.html` (used by the first mastery level) can
 be found in `extas` directory.
 
 3. I'm a frontend developer!<br/>
-`sugar-qsp game.txt -c -o game.js`<br/>
+`txt2web game.txt -c -o game.js`<br/>
 It just builds the game script into a js you can put on your website. To run
 the game execute `SugarQSP.start()`

 Есть три уровня мастерства.
 
 1. **Просто собери мне игру**:<br/>

 2. **Я знаю что делаю**:<br/>

 Если вы знаете что делаете, то для вас смысл опций очевиден. `body.html` и `default.css`
 лежат в каталоге `extras`.

 сайте как вам угодно.
