+== Prism Integration ==
+
+This extension allows source code to be syntax highlighted on wiki pages.
+
+This works as a drop-in replacement for the Highlightjs Integration by Nikus Pokus.
+
+== Requirements ==
+
+This version of the extension has been tested with Prism 1.23.0 and MediaWiki
+1.35.1.
+
+== Installation ==
+
+Add this line to your LocalSettings.php:
+
+    wfLoadExtension( 'PrismHighlight' );
+
+By default, this extension will use a bundled copy of Prism 1.23.0 with the
+following customizations:
+
+* Plugins: Line Highlight, Line Numbers, Match braces, Diff Highlight
+* Languages: Markup + HTML + XML + SVG + MathML + SSML + Atom + RSS, CSS, 
+C-like, JavaScript, ABNF, ANTLR4, Bash + Shell, Batch, BNF + RBNF, C, Clojure,
+CSS Extras, CSV, Diff, EBNF, Git, GLSL, Groovy, .ignore + .gitignore + .hgignore
++ .npmignore, Ini, Java, JavaDoc, JavaDoc-like, Java stack trace, JSON + Web
+App Manifest, JSON5, Kotlin + Kotlin Script, Less, Lisp, Lua, Markdown, Markup
+templating, PHP, PHPDoc, PHP Extras, PowerShell, .properties, Python, Sass (Sass),
+Sass (Scss), Scala, Shell session, SQL, TOML, YAML
+* Theme: Tomorrow Night
+
+If you wish to use a different copy of the library, download it from the PrismJS 
+website (https://prismjs.com) and replace the files in the 'prism' folder.
+
+== Usage ==
+
+You can use "syntaxhighlight" or "source" elements for code blocks.
+
+The following attributes can be used:
+ * lang;        Defines the language
+ * inline;      Formats the source code to be inline, as part of a paragraph.
+ * class;       Defines extra HTML classes to be added.
+ * id;          Defines the id attribute of the resulting HTML output.
+
+== Manual Configuration ==
+
+You may edit the 'extension.js' file to adjust the configuration of the extension, in
+the "config" area.
+
+* HighlightTags;    The tags which will be processed for syntax highlighting.
+* LangMapping;      Custom mappings of language keys to other language keys.
