 ReMKiT1D is a framework for building 1D multi-fluid models of the tokamak Scrape-Off Layer with support for kinetic electron effects and collisional-radiative modelling. The framework is controlled through a Python interface available [here](https://github.com/ukaea/ReMKiT1D-Python). The global user manual, covering both the framework and the Python wrappers, is available on the Python repository. Requirements and installation instructions for ReMKiT1D can also be found [here](https://ukaea.github.io/ReMKiT1D/)
