 # A template jupyter book documentation repository
 
+This is a template repository that can be used when generating documentation using [Jupyter-books](https://github.com/executablebooks/jupyter-book) and hosting the site via GitHub pages.
+
+## Working with this project locally
+
+You can get this project working locally by using the environment.yml file to create a conda environment that contains all the dependencies required to get started.
+
+```{bash}
+$ git clone https://github.com/ARCTraining/template-jb-docs.git
+
+$ conda env create -f environment.yml
+```
+
+To build the html content locally you can use the `jupyter-book` command line tool:
+
+```{bash}
+# navigate to the repository root
+$ cd template-jb-docs
+# sometimes worth running jupyter-book clean book/ to remove old files
+$ jupyter-book build book/
+```
+### Windows
+
+An important note is that the JupyterBook project does not currently support Windows ([see here for more](https://jupyterbook.org/advanced/advanced.html#working-on-windows)).
+
+To aid with this we have created a `Vagrantfile` that can allow Windows users who have a virtualisation provider installed (such as [VirtualBox](https://www.virtualbox.org/)) and [Vagrant](https://www.vagrantup.com/) installed to create a headless virtual Linux machine that will build the jupyter book. You can do this with the following steps once you've installed a virtualisation provider and vagrant:
+```
+# within git-bash or powershell
+$ cd template-jb-docs
+$ vagrant up
+
+# to rebuild the site after changes with the vagrant box running
+$ vagrant reload --provision
+
+# don't forget to destroy the box when you're done
+$ vagrant destroy
+```
+
+This will build the jupyter-book html files on your Windows file system (by navigating via /vagrant) so your local build will still persist after you've destroyed your vagrant box.
