# TWiki Add-Ons _Add functionality to TWiki with extensions not based on the TWiki scripts._ ## Overview An add-on runs separately from the TWiki scripts, e.g. for data import, export to static HTML, etc. Add-Ons normally do not call any TWiki code directly, though may invoke TWiki scripts. There are different types on add-ons, they may be stand alone scripts, browser plugins, office tool extensions, or even a set of TWiki topics that form a TWiki application. **_Relevant links on TWiki.org:_** - TWiki:Plugins.AddOnPackage - list of all contributed add-on scripts - TWiki:Plugins.AddOnDevelopment - discussion and feedback on contributed add-on scripts - TWiki:Plugins.AddOnBrainstorming - open forum for new add-on script ideas - TWiki:Plugins.AddOnPackageHowTo - instructions and template to create a new add-on topic **_See other types of extensions:_** [[TWikiContribs]], [[TWikiPlugins]], [[TWikiSkins]] ## Add-Ons Installed on this TWiki # TWiki Installation Error Incorrect format of searchformat template (missing sections?
