 ## Usage
 
 Diff2Html can be used in various ways as listed in the [distributions](#distributions) section. The two main ways are:
 
-- [Diff2Html](#diff2html-usage): using the parser and html generator directly from the library gives you complete
-  control about what you can do with the json or html generated.
 - [Diff2HtmlUI](#diff2htmlui-usage): using this wrapper makes it easy to inject the html in the DOM and adds some nice
   features to the diff, like syntax highlight.
+- [Diff2Html](#diff2html-usage): using the parser and html generator directly from the library gives you complete
+  control about what you can do with the json or html generated.
 
-Bellow you can find more details and exemples about each option.
+Below you can find more details and examples about each option.
 
-## Diff2Html Usage
+## Diff Text Input
 
-To load correctly in the Browser you always need to include the stylesheet in the final HTML.
-
-Import the stylesheet
-
-```html
-<!-- CSS -->
-<link rel="stylesheet" type="text/css" href="bundles/css/diff2html.min.css" />
-```
-
-You can also refer to it from a CDN like [CDNJS](https://cdnjs.com/libraries/diff2html).
-
-### Diff2Html API
-
-> JSON representation of the diff
-
-```ts
-function parse(diffInput: string, configuration: Diff2HtmlConfig = {}): DiffFile[];
-```
-
-> Pretty HTML representation of the diff
-
-```ts
-function html(diffInput: string | DiffFile[], configuration: Diff2HtmlConfig = {}): string;
-```
-
-> Check out the [docs/demo.html](./docs/demo.html) for a demo example.
-
-### Diff2Html Configuration
-
-The HTML output accepts a Javascript object with configuration. Possible options:
-
-- `outputFormat`: the format of the output data: `'line-by-line'` or `'side-by-side'`, default is `'line-by-line'`
-- `drawFileList`: show a file list before the diff: `true` or `false`, default is `true`
-- `diffStyle`: show differences level in each line: `word` or `char`, default is `word`
-- `matching`: matching level: `'lines'` for matching lines, `'words'` for matching lines and words or `'none'`, default
-  is `none`
-- `matchWordsThreshold`: similarity threshold for word matching, default is `0.25`
-- `matchingMaxComparisons`: perform at most this much comparisons for line matching a block of changes, default is
-  `2500`
-- `maxLineSizeInBlockForComparison`: maximum number os characters of the bigger line in a block to apply comparison,
-  default is `200`
-- `maxLineLengthHighlight`: only perform diff changes highlight if lines are smaller than this, default is `10000`
-- `renderNothingWhenEmpty`: render nothing if the diff shows no change in its comparison: `true` or `false`, default is
-  `false`
-- `compiledTemplates`: object with previously compiled templates to replace parts of the html
-- `rawTemplates`: object with raw not compiled templates to replace parts of the html
-  > For more information regarding the possible templates look into
-  > [src/templates](https://github.com/rtfpessoa/diff2html/tree/master/src/templates)
-
-### Diff2Html Browser
-
-Import the stylesheet and the library code
-
-```html
-<!-- CSS -->
-<link rel="stylesheet" type="text/css" href="bundles/css/diff2html.min.css" />
-
-<!-- Javascripts -->
-<script type="text/javascript" src="bundles/js/diff2html.min.js"></script>
-```
-
-It will now be available as a global variable named `Diff2Html`.
-
-```js
-document.addEventListener('DOMContentLoaded', () => {
-  var diffHtml = global.Diff2Html.html('<Unified Diff String>', {
-    drawFileList: true,
-    matching: 'lines',
-    outputFormat: 'side-by-side',
-  });
-  document.getElementById('destination-elem-id').innerHTML = diffHtml;
-});
-```
-
-### Diff2Html NPM / Node.js Library
-
-```js
-const Diff2html = require('diff2html');
-const diffJson = Diff2html.parse('<Unified Diff String>');
-const diffHtml = Diff2html.html(diffJson, { drawFileList: true });
-document.getElementById('destination-elem-id').innerHTML = diffHtml;
-```

+diff2html accepts the text contents of a
+[unified diff](https://www.gnu.org/software/diffutils/manual/html_node/Unified-Format.html) or the superset format git
+diff (https://git-scm.com/docs/git-diff) (not combined or word diff). To provide multiples files as input just
+concatenate the diffs (just like the output of git diff).

+
+## Diff2Html Usage
+
+### Diff2Html API
+
+> JSON representation of the diff
+
+```ts
+function parse(diffInput: string, configuration: Diff2HtmlConfig = {}): DiffFile[];
+```
+
+> Pretty HTML representation of the diff
+
+```ts
+function html(diffInput: string | DiffFile[], configuration: Diff2HtmlConfig = {}): string;
+```
+
+### Diff2Html Configuration
+
+The HTML output accepts a Javascript object with configuration. Possible options:
+
+- `outputFormat`: the format of the output data: `'line-by-line'` or `'side-by-side'`, default is `'line-by-line'`
+- `drawFileList`: show a file list before the diff: `true` or `false`, default is `true`
+- `srcPrefix`: add a prefix to all source (before changes) filepaths, default is `''`. Should match the prefix used when
+  [generating the diff](https://git-scm.com/docs/git-diff#Documentation/git-diff.txt---src-prefixltprefixgt).
+- `dstPrefix`: add a prefix to all destination (after changes) filepaths, default is `''`. Should match the prefix used
+  when [generating the diff](https://git-scm.com/docs/git-diff#Documentation/git-diff.txt---dst-prefixltprefixgt)
+- `diffMaxChanges`: number of changed lines after which a file diff is deemed as too big and not displayed, default is
+  `undefined`
+- `diffMaxLineLength`: number of characters in a diff line after which a file diff is deemed as too big and not
+  displayed, default is `undefined`
+- `diffTooBigMessage`: function allowing to customize the message in case of file diff too big (if `diffMaxChanges` or
+  `diffMaxLineLength` is set). Will be given a file index as a number and should return a string.
+- `matching`: matching level: `'lines'` for matching lines, `'words'` for matching lines and words or `'none'`, default
+  is `none`
+- `matchWordsThreshold`: similarity threshold for word matching, default is `0.25`
+- `maxLineLengthHighlight`: only perform diff changes highlight if lines are smaller than this, default is `10000`
+- `diffStyle`: show differences level in each line: `'word'` or `'char'`, default is `'word'`
+- `renderNothingWhenEmpty`: render nothing if the diff shows no change in its comparison: `true` or `false`, default is
+  `false`
+- `matchingMaxComparisons`: perform at most this much comparisons for line matching a block of changes, default is
+  `2500`
+- `maxLineSizeInBlockForComparison`: maximum number of characters of the bigger line in a block to apply comparison,
+  default is `200`
+- `compiledTemplates`: object ([Hogan.js](https://github.com/twitter/hogan.js/) template values) with previously
+  compiled templates to replace parts of the html, default is `{}`. For example:
+  `{ "tag-file-changed": Hogan.compile("<span class="d2h-tag d2h-changed d2h-changed-tag">MODIFIED</span>") }`
+- `rawTemplates`: object (string values) with raw not compiled templates to replace parts of the html, default is `{}`.
+  For example: `{ "tag-file-changed": "<span class="d2h-tag d2h-changed d2h-changed-tag">MODIFIED</span>" }`
+  > For more information regarding the possible templates look into
+  > [src/templates](https://github.com/rtfpessoa/diff2html/tree/master/src/templates)
+- `highlightLanguages`: Map of extension to language name, used for highlighting. This overrides the default language
+  detection based on file extensions.
+- `colorScheme`: color scheme to use for the diff, default is `light`. Possible values are `light`, `dark`, and `auto`
+  which will use the browser's preferred color scheme.
+
+### Diff2Html Browser
+
+Import the stylesheet and the library code.
+
+To load correctly in the Browser you need to include the stylesheet in the final HTML.
+
+```html
+<!-- CSS -->
+<link rel="stylesheet" type="text/css" href="https://cdn.jsdelivr.net/npm/diff2html/bundles/css/diff2html.min.css" />
+
+<!-- Javascripts -->
+<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/diff2html/bundles/js/diff2html.min.js"></script>
+```
+
+It will now be available as a global variable named `Diff2Html`.
+
+```js
+document.addEventListener('DOMContentLoaded', () => {
+  var diffHtml = Diff2Html.html('<Unified Diff String>', {
+    drawFileList: true,
+    matching: 'lines',
+    outputFormat: 'side-by-side',
+  });
+  document.getElementById('destination-elem-id').innerHTML = diffHtml;
+});
+```
+
+### Diff2Html NPM / Node.js Library
+
+```js
+const Diff2html = require('diff2html');
+const diffJson = Diff2html.parse('<Unified Diff String>');
+const diffHtml = Diff2html.html(diffJson, { drawFileList: true });
+console.log(diffHtml);
