+Jekyll Scholar Configuration Detail
+===================================
+We desire the output URL structure to be:
+* `/publications/`
+  * `index.html` - a page listing the entire bibliography
+  * `publications.bib` - the raw bibtex file, directly from the source
+  * `Key.html` - details page generated for each publication
+  * `Key.*` - Any files associated with each publication, copied directly from the source
+
+In the `scholar` section of the configuration file, configuration options we've used are:
+* `source`: Directory in which our bibtex files are to be found (`publications`)
+* `details_dir`: Directory to output `Key.html` files for each publication (`publications`), rendered using the layout
+  defined in the `details_layout` option.
+* `details_link`: We override the default here, as we generate our own HTML to render this link in our
+  `bibliography_template`.
+* `repository`: Location of files associated with publications (`publications`) (the same
+  directory is used for both input and output: it is handled as usual by jekyll)
+
+The template used to generate individual publication pages is [here](_layouts/publication.html). The part of interest is
+the Source Materials section. We iterate through a
+[predefined list of file types](publications/_publication_file_types.yml) and output a link (using icon and text from
+the file type list) to the file in the repository if it exists.
+
+Finally, in order to generate the complete biography page, we use a [page](publications.html) in the site's root just
+outputting a `{% bibliography %}` as normal (which renders each entry using the layout defined by the scholar
+`bibliography_template` option). By using a `permalink` jekyll option we place the rendered bibliography into the
+`/publications/` output directory as `index.html`.

 Testing and Deployment

 An additional check that external links are still live is also run, but this test is permitted to fail without blocking

-The site is deployed to `/vol/rr/www` automatically on successful build.
+The site should be deployed automatically by GitLab CI. To deploy the site manually from your own machine, run the `.deploy.sh` script. This will use `rsync` to synchronise the contents of the `_site` directory with the webserver via SSH. Default deployment parameters:
+* DOC_DEPLOY_USER: the default username used by SSH to connect, usually the username on your local machine
+* DOC_DEPLOY_SERVER: `shell1.doc.ic.ac.uk`
+* DOC_DEPLOY_PATH: `/vol/rr/www`
+To override these parameters, set shell variables, eg: `DOC_DEPLOY_USER=me ./.deploy.sh`
+
+The site is deployed to `/vol/rr/www` automatically on successful build using the `.deploy.sh` script.
+The contents of the `DOC_DEPLOY_KEY` CI environment variable are used
+as the private key used to authenticate with the server. This key is currently configured to give locked-down rsync access to the
+`/vol/rr/www` using `pg`'s user account. For further details for how this is achieved, [see this
+howto](https://www.guyrutenberg.com/2014/01/14/restricting-ssh-access-to-rsync/). Note: when deploying to a locked-down
+rsync account, the DOC_DEPLOY_PATH should be set to a path relative to the lockdown path -- use `.` if in doubt. You
+won't need to set this if you're deploying from your own user account.
