# Installation
**epidemia** requires R v3.5.0 or above. The latest version of R can be downloaded
[here](https://cloud.r-project.org/bin/).
The package can be installed directly from
github. However, this requires you to have a working C++ toolchain. To ensure that this
is working, please first install **rstan** by following these
[installation instructions](https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started).
After installing **rstan**, running
wzxhzdk:0
will install the latest development version of **epidemia**.
If using windows, you can alternatively install the [binary](https://github.com/ImperialCollegeLondon/epidemia/releases/latest).
Vignettes are not currently included in the package because they are
computationally demanding, and are best viewed online.
