+#### Add language-specific stemmer and/or filter
+
+> __Stemmer:__ several linguistic mutations of the same word (e.g. "run" and "running")
+
+> __Filter:__ a blacklist of words to be filtered out from indexing at all (e.g. "and", "to" or "be")
+
+Define a private custom stemmer or filter during creation/initialization:
+```js
+var index = new FlexSearch({
+
+    stemmer: {
+        
+        // object {key: replacement}
+        "ational": "ate",
+        "tional": "tion",
+        "enci": "ence",
+        "ing": ""
+    },
+    filter: [ 
+        
+        // array blacklist
+        "in",
+        "into",
+        "is",
+        "isn't",
+        "it",
+        "it's"
+    ]
+});
+```
+
+Or assign stemmer/filters globally to a language:
+```js
+FlexSearch.registerLanguage('us', {
+
+    stemmer: {/* ... */},
+    filter: [/* ... */]
+});
+```
+
+Or use built-in stemmer or filter of your preferred languages:
+```html
+<html>
+<head>
+    <script src="js/flexsearch.min.js"></script>
+    <script src="js/lang/en.min.js"></script>
+    <script src="js/lang/de.min.js"></script>
+</head>
+...
+```
+
+Now you can assign built-in stemmer during creation/initialization:
+```js
+var index_en = new FlexSearch({stemmer: 'en', filter: 'en'});
+var index_de = new FlexSearch({stemmer: 'de', filter: [/* custom */]});
+```
+
+In Node.js you just need require the language pack files to make them available:
+
+```js
+require('lang/en.js');
+require('lang/de.js');
+```
+
+It is also possible to <a href="#builds">compile language packs into the build</a> as follows:
+
+```bash
