Unless [extensions.scriptish.cache.enabled](https://github.com/scriptish/scriptish/wiki/Manual%3A-Preferences#wiki-boolean-extensionsscriptishcacheenabled--new-in-scriptish) is `true`, Scriptish loads scripts from disk each time they are required. Linking the scripts in Scriptish profile directory into git tree allows easier development, it is not necessary to reinstall Wiki Monkey after each change.
