+Fixes should be posted to the Bug Tracker
+http://sourceforge.net/p/scintilla/bugs/
+
+Features should be posted to the Feature Request Tracker
+http://sourceforge.net/p/scintilla/feature-requests/
+
+Either send unified diffs (or patch files) or zip archives with whole files.
+Mercurial patch files are best as they include author information and commit
+messages.
+
+Questions should go to the scintilla-interest mailing list
+https://groups.google.com/forum/#!forum/scintilla-interest
+
+Code should follow the guidelines at
+http://www.scintilla.org/SciCoding.html
+
+Do not use SourceForge's Merge Request mechanism or message sending
+feature as no one is monitoring these.
+The neilh @ scintilla.org account receives much spam and is only checked
+occasionally. Almost all Scintilla mail should go to the mailing list.

 *** Windows version ***

+A C++ 17 compiler is required.
+Visual Studio 2017 is the development system used for most development

      many ways.
      Each has windows, menus and bitmaps. These features generally work in similar ways so each
      has a way to move a window or draw a red line. Sometimes one platform requires a sequence of
      calls rather than a single call. At other times, the differences are more profound. Reading
      the Windows clipboard occurs synchronously but reading the GTK+ clipboard requires a request
      call that will be asynchronously answered with a message containing the clipboard data.

-      red, say #400000, it may only be allocated an already available colour such as #800000 or

+        </h2>
+        <p>
+                Scintilla contains lexers for various types of languages:
+                <ul>
+                        <li>Programming languages like C++, Java, and Python.</li>
+                        <li>Assembler languages are low-level programming languages which may additionally include instructions and registers.</li>
+                        <li>Markup languages like HTML, TeX, and Markdown.</li>
+                        <li>Data languages like EDIFACT and YAML.</li>
+                </ul>
+        </p>
+        <p>
+                Some languages can be used in different ways. JavaScript is a programming language but also
+                the basis of JSON data files. Similarly,
+                <a href="https://en.wikipedia.org/wiki/S-expression">Lisp s expressions</a> can be used for both source code and data.
+        </p>
+        <p>
+                Each language type has common elements such as identifiers in programming languages.
+                These common elements should be identified so that languages can be displayed with common
+                styles for these elements.
+                Style tags are used for this purpose in Scintilla.
+        </p>
+        <h2>
+                Style Tags
+        </h2>
+        <p>
+                Every style has a list of tags where a tag is a lower-case word containing only the common ASCII letters 'a'-'z'
+                such as "comment" or "operator".
+        </p>
+        <p>
+                Tags are ordered from most important to least important.
+        </p>
+        <p>
+                While applications may assign visual attributes for tag lists in many different ways, one reasonable technique is to
+                apply tag-specific attributes in reverse order so that earlier and more important tags override less important tags.
+                For example, the tag list <code>"error comment documentation keyword"</code> with
+                a set of tag attributes <br />
+                <code>{ comment=fore:green,back:very-light-green,font:Serif documentation=fore:light-green error=strikethrough keyword=bold }</code><br />
+                could be rendered as <br />
+                <code>bold,fore:light-green,back:very-light-green,font:Serif,strikethrough</code>.
+        </p>
+        <p>
+                Alternative renderings could check for multi-tag combinations like
+                <code>{ comment.documentation=fore:light-green comment.line=dark-green comment=green }.</code>
+        </p>
+        <p>
+                Commonly, a tag list will contain an optional embedded language; optional statuses; a base type; and a set of type modifiers:<br />
+                <code>embedded-language? status* base-type modifiers*</code>
+        </p>
+        <h3>Embedded language</h3>
+        <p>
+                The embedded language may be a source <code>(client | server)</code> followed by a language name
+                <code>(javascript | php | python | basic)</code>.
+                This may be extended in the future with other programming languages and style-definition languages like CSS.
+        </p>
+        <h3>Status</h3>
+        <p>
+                The statuses may be <code>(error | unused | predefined | inactive)</code>.<br />
+                The <code>error</code> status is used for lexical statuses that indicate errors in the source code such as unterminated quoted strings.<br />
+                The <code>unused</code> status may indicate a gap in the lexical states, possibly because an old lexical class is no longer used or an upcoming lexical class may fill that position.<br />
+                The <code>predefined</code> status indicates a style in the range 32.39 that is used for non-lexical purposes in Scintilla.<br />
+                The <code>inactive</code> status is used for text that is not currently interpreted such as C++ code that is contained within a '#if 0' preprocessor block.
+        </p>
+        <h3>Basic Types</h3>
+        <p>
+                The basic types for programming languages are <code>(default | operator | keyword | identifier | literal | comment | preprocessor | label)</code>.<br />
+                The <code>default</code> type is commonly used for spaces and tabs between tokens although it may cover other characters in some languages.
+        </p>
+        <p>
+                Assembler languages add <code>(instruction | register)</code>. to the basic types from programming languages.<br />
+        </p>
+        <p>
+                The basic types for markup languages are <code>(default | tag | attribute | comment | preprocessor)</code>.<br />
+        </p>
+        <p>
+                The basic types for data languages are <code>(default | key | data | comment)</code>.<br />
+        </p>
+        <h3>Comments</h3>
+        <p>
+                Programming languages may differentiate between line and stream comments and treat documentation comments as distinct from other comments.
+                Documentation comments may be marked up with documentation keywords.<br />
+                The additional attributes commonly used are <code>(line | documentation | keyword | taskmarker)</code>.
+        </p>
+        <h3>Literals</h3>
+        <p>
+                Programming and assembler languages contain a rich set of literals including numbers like <code>7</code> and <code>3.89e23</code>; <code>"string\n"</code>; and <code>nullptr</code>
+                and differentiating between these is often wanted.<br />
+                The common literal types are <code>(numeric | boolean | string | regex | date | time | uuid | nil | compound)</code>.<br />
+                Numeric literal types are subdivided into <code>(integer | real)</code>.<br />
+                String literal types may add (perhaps multiple) further attributes from <code> (heredoc | character | escapesequence | interpolated | multiline | raw)</code>.<br />
+        </p>
+        <p>
+                An escape sequence within an interpolated heredoc may thus be <code>literal string heredoc escapesequence</code>.

+                Each element in this scheme may be extended in the future. This may be done by revising this document to provide a common approach to new features.
+                Individual lexers may also choose to expose unique language features through new tags.
+        </p>
+        <h2>
+                Translation
+        </h2>
+        <p>
+                Tags could be exposed directly in user interfaces or configuration languages.
+                However, an application may also translate these to match its naming schema.
+                Capitalization and punctuation could be different (like <code>Here-Doc</code> instead of <code>heredoc</code>),
+                terminology changed ("constant" instead of "literal"),
+                or human language changed from English to Chinese or Spanish.
+        </p>
+        <p>
+                Starting from a common set of tags makes these modifications tractable.
+        </p>
+        <h2>
+                Open issues
+        </h2>
+        <p>
+                The C++ lexer (for example) has inactive states and dynamically allocated substyles.
+                These should be exposed through the metadata mechanism but are not currently.
+        </p>
