The following instructions assume the use of TiddlyWebWiki.

Setting Up an Instance with the DevStore

install the devstore plugin
use the included twinstance_dev script to create a preconfigured dev instance
- alternatively, download tiddlywebconfig.py from this repository (via the raw link) to a temporary directory and, from the same directory, run twinstance to create a new instance
in the new instance directory, modify or extend tiddlywebconfig.py's local_instance_tiddlers entry to point to the desired tiddlers on the local hard drive
changes to the specified tiddlers will be reflected on a simple page reload in the browser

Modifying an Existing Plugin

TiddlyWebWiki uses Cook-style recipes to indicate the default set of tiddlers in the system bag.

If the path in the instance's local_instance_tiddlers is set up properly, the local plugin files can be modified directly.

Adding a New Plugin

create a .js file along with a .meta file (example)
extend local_instance_tiddlers with the path to the .js file:

'local_instance_tiddlers': {
    'system': [
        '../../../TiddlyWiki/svn.tiddlywiki.org/Trunk/verticals/TiddlyWebWiki/index.recipe',
        '/path/to/foo.js'
    ]
}
