+# Stylus Supremacy
+
+**Stylus Supremacy** is a **Node.js** script for formatting *Stylus* files. You may say this is a beautifier of *Stylus*.
+
+## Basic usage
+
+First thing first, you must install this script via **NPM** by calling `npm install stylus-supremacy -g`, then calling the below command.
+```
+node stylus-supremacy ./path/to/your/file.styl
+```
+
+In case you want to format multiple files at a time, you can specify a file path in *glob* pattern.
+```
+node stylus-supremacy ./**/*.styl
+```
+
+## Formatting options
+
+The [default formatting options](edge/defaultFormattingOptions.json) will be used, unless you specify your own options explicitly. The parameter `--options` and `-p` can be used interchangably.
+```
+node stylus-supremacy ./path/to/your/file.styl --options ./path/to/your/options.json
+```
+
+|Options|Default value|Possible values|
+|---|---|---|
+|`insertColons`|`true`|`true` for always inserting a colon after a property name, otherwise `false`.|
+|`insertSemicolons`|`true`|`true` for always inserting a semi-colon after a property value, a variable declaration, a variable assignment and a function call, otherwise `false`.|
+|`insertBraces`|`true`|`true` for always inserting a pair of curly braces between a selector body, a mixin body, a function body and any @-block bodies, otherwise `false`.|
+|`insertNewLineBetweenGroups`|`1`|This represents a number of new-line between different type of groups.|
+|`insertNewLineBetweenSelectors`|`false`|`true` for always inserting a new-line between selectors, otherwise `false`.|
+|`insertNewLineBeforeElse`|`false`|`true` for always inserting a new-line before *else* keyword, otherwise `false`.|
+|`insertSpaceBeforeComment`|`true`|`true` for always inserting a white-space before a comment, otherwise `false`.|
+|`insertSpaceAfterComment`|`true`|`true` for always inserting a white-space after a comment, otherwise `false`.|
+|`insertParenthesisAroundIfCondition`|`true`|`true` for always inserting a pair of parentheses between *if*-condition, otherwise `false`.|
+|`tabStopChar`|`\t`|This represents a tab-stop string. You may change this to 2-white-space sequence or anything.|
+|`newLineChar`|`\n`|This represents a new-line character. You may change this to `\r\n` if you are using *Microsoft Windows*.|
+|`quoteChar`|`'`|This represents a quote character that is used to begin and terminate a string. You must choose either single-quote or double-quote.|
+|`sortProperties`|`false`|`false` for doing nothing about the CSS property order. `alphabetical` for sorting CSS properties from A to Z. `grouped` for sorting CSS properties according to *[Stylint](https://github.com/SimenB/stylint/blob/master/src/data/ordering.json)*.|
+|`alwaysUseImport`|`false`|`true` for always using *@import* over *@require*. The difference between *@import* and *@require* is very subtle. Please refer to [the offical guide](http://stylus-lang.com/docs/import.html#require).|
+|`alwaysUseNot`|`false`|`true` for always using *not* keyword over *!* operator, otherwise `false`.|
+
+## Writing the formatted output to a file
+
+Normally, running the command will print out the formatted content to the output stream (console). However, you may write the formatted content to a file (or many files, if the pattern matches more than one files) by specifying `--outDir` or `-o`, and followed by the path to an output directory.
+```
+node stylus-supremacy ./path/to/your/file.styl --outDir ./path/to/output/directory
+```
+
+Alternatively, you may overwrite the original file with the formatted output by specifying `--replace` or `-r` parameter.
+```
+node stylus-supremacy ./path/to/your/file.styl --replace
+```
+
+Note that `--outDir` and `--replace` will not work together. You have to choose just one.
+
+## Using this as an NPM module
+
+Simply include *stylus-supremacy/edge/format* and call it with *Stylus* content as a string and formatting options as an object (see above topic).
+```
+const format = require('stylus-supremacy/edge/format')
+
+const stylus = `
+body
+  display none
+`
+
+const options = {
+  insertColons: true,
+  insertSemicolons: true,
+  insertBraces: true
+}
+
+console.log(format(stylus, options))
+```
+
+The stream output prints:
+```
+body {
+  display: none;
+}
+```
