Developer Documentation


Hotaru has been developed with a focus on flexibility and scalability of the code. The core files for Hotaru are extremely light and relay upon a set of plugins to provide functionality for the Site. The plugins are where Hotaru really comes to life.

The core set of plugins which are installed on a typical Hotaru installation have been created by the developers of Hotaru giving thought to the most common uses required for a Site build. We fully expect that users will think of their own uses for Hotaru and may have the need to build upon Hotaru's core framework.

This section of the Codex offers guidelines and references for anyone wishing to modify, extend, or contribute to Hotaru.

CAUTION: Programming Required
In the following we are discussing ways in which you can program Hotaru, change Theme designs and 'dig into' the plugin's code to change the way Hotaru works for you. The level of detail here is beyond what most non-programmer users require. If you run into difficulty, you may post questions to the Hotaru Forums.
