+title: Contributing to the TiddlyWiki Core
+type: text/vnd.tiddlywiki
+
+The TiddlyWiki core is the container for all the generic features of TiddlyWiki that are of universal utility. Concretely, it comprises the tiddlers in the `$:/core` plugin.
+
+! Core Contribution Requirements
+
+There are requirements that must be met for any contribution that is to be accepted into the core:
+
+* If appropriate, the new functionality must support both standalone and Node.js configurations. For example, any new widgets must be capable of being rendered on the server
+* The contribution must not compromise the backwards compatibility of the existing code
+* Code contributions must comply with the [[TiddlyWiki Coding Style Guidelines]]
+* Generic components are preferred over point solutions for specific problems (which belong in plugins)
+
+! The Core and Innovation
+
+If you've created something new and innovative, don't try to rush to get it included into the core. Once new stuff is in the core it is subject to the core policies of strict backwards compatibility, making it frozen as far as radical innovation is concerned. It's usually better to release the new thing as a plugin so that it can be shared with the rest of the community for feedback.
+
+The expected model of innovation is that the core development will move relatively slowly as more and more of the initial planned functionality is implemented. Innovation can take place in the much more unconstrained environment of plugins. Over time, as these third party plugins gain popularity and become more polished, some or all of their functionality will be migrated into the core.

+title: Contributing to the TiddlyWiki Plugin Library
+type: text/vnd.tiddlywiki
+
+The TiddlyWiki Plugin library is the set of plugins, themes and languages that are distributed via http://tiddlywiki.com.
+
+The plugin library is intended to help end users of TiddlyWiki in the following ways:
+
+* By being a reliable, official source of community assets
+* Permitting automatic upgrading of plugins during the upgrade process
+* Providing a guarantee of backwards compatibility
+
+Plugins in the library need a maintainer who is prepared to make a commitment to keep them tested and fully operational with successive releases of the core code. Many plugins are maintained by the core team.

 ! Guidelines
 
+This list of guidelines isn't exhaustive but captures some of the common problems. The ultimate guide is the existing TiddlyWiki code-base. There are still some places where the coding guidelines aren't used consistently within the core; pull requests are welcome to help resolve those issues.
