I just saw this! It could have been probably a separate question. Here is the instruction to how to set up Honeybee[+]:

> Dear Ladybug community, [After more than a year of development](https://github.com/ladybug-tools/honeybee/graphs/contributors), we are very excited to finally have a public release for Honeybee[+]. As most of you already know by now, Honeybee[+] is one of our [+] developments, which is an attempt to make Honeybee platform-agnostic, cloud-compatible, scalable and more flexible for development. It currently consists of a [core python library](https://github.com/ladybug-tools/honeybee) and the plugin libraries for [Grasshopper](https://github.com/ladybug-tools/honeybee-grasshopper) and [Dynamo](https://github.com/ladybug-tools/honeybee-dynamo). You can download the plugin for Grasshopper from [food4Rhino](http://www.food4rhino.com/app/ladybug-tools) and in…

If you want to know what’s going under the hood here is a tutorial:

> As most of you are aware, earlier this year [we officially released Honeybee[+]](http://discourse.ladybug.tools/t/honeybee-0-0-3-for-grasshopper-and-dynamo-release/2024). In that post we mentioned a comprehensive tutorial for Matrix-based daylighting simulation with Radiance will be released by LBNL in a near future. We’re excited to finally share the good news that the report is officially released and can be downloaded from [Radiance-online tutorials page](https://www.radiance-online.org/learning/tutorials/). See the pdf file for “Daylighting Simulations with Radiance using Matrix-based Methods“ and the examples for the tutor…

Daysim is only used by Honeybee and not Honeybee[+] and you can download it from Daysim’s website: [http://daysim.ning.com/page/download](http://daysim.ning.com/page/download)
