+Personas are loaded from configuration files, which can either be directly provided by plugins or user-defined JSON files. 
 
 By default, personas are loaded from the XDG configuration directory, just create .json files under `~/.config/ovos_persona`
 
+Personas are mainly defined via [solver plugins](https://openvoiceos.github.io/ovos-technical-manual/solvers/), each plugin is tried by order until one provides an answer

+Find solver plugins [here](https://github.com/OpenVoiceOS?q=solver&type=all), some solvers may also use other solvers internally, such as a [MOS (Mixture Of Solvers)](https://github.com/TigreGotico/ovos-MoS)

+- search online knowledge bases (wolfram alpha, wikipedia...)
+- fall back to wordnet when offline for dictionary look up
+- finally use a local chatbot (rivescript) for general chitchat
+- the failure solver ensures the persona speaks an error if all solvers fail
