 To get started, simply copy the desired workflow file to your repository and adapt it to your needs:
 
 - `_tools/build.yml` -> `.github/workflows/build.yml`
 
-Hidden rooms, speakers, or talks are automatically generated in way containing no content. In order to remove these empty files simply add a file called `delete_hidden.sh` to the root with the following content. It will automatically called by the `build` workflow (if available) to delete the files.

 ## Configuration
 
 All configurations and customization for this theme are stored under the `conference` property in the `_config.yml` file. You can find an example configuration containing most of the here discussed parameters under `_config.example.yml` in this repository.

 In order to help users navigating the program during the congress, a _Live_ indication can be shown next to talks which are currently taking place. A small JavaScript functions keeps the site automatically up-to-date (without the need to refresh) showing the indication as soon as the talk has started and hiding it once it is over (according to the timetable indicated in the `_data/program.yml` file).
 
 This can be further extended if some of the talks have an associated live stream: Upon clicking one of the live indications a modal will open containing the corresponding live stream embedded. The URL to the live stream has to be set via `live` property in each room (see the _Content_ > _Room_ section below).

 The different talks, speakers and rooms are stored as a collection of file. Each file contains a small header in form of a YAML block (called [FrontMatter](https://jekyllrb.com/docs/front-matter/)) which is used to store additional information beside a description.
 The actual schedule defining when and in which room a talk takes place is stored as a [YAML data file](https://jekyllrb.com/docs/datafiles/).
