+This package serves as a template for presentations in the [Corporate Design of KIT](https://kit-cd.sts.kit.edu/praesentationen.php) (version from February 2025).
+
+It is modified from the template developed by the research group [DSiS](https://dsis.kastel.kit.edu) at the KIT Faculty of Computer Science and is based on [LaTeX Beamer](https://ctan.org/pkg/beamer).

+# Usage
+=====
+
+## Options for the `CELbeamer` document class
+------------------------------------------
+The font size in the footer is set larger by default than in the PowerPoint template. This can be enforced to match the original specification using the `smallfoot` option.
+
+| Footer font size         | Option               |
+| ---------------------    | -------------------- |
+| slightly larger (12pt)   | `bigfoot` (default)  |
+| KIT specification (11pt) | `smallfoot`          |
+
+German and English are available as languages. The language selection automatically sets the appropriate formats (e.g., quotation marks, date).
+
+| Language  | Option          |
+| --------- | --------------- |
+| German    | `de`            |
+| English   | `en`  (default) |
+
+Slide titles are set in Helvetica. If you want Franklin Gothic for everything, you can define this.
+
+| Title font        | Option                |
+| ----------------- | --------------------- |
+| Franklin Gothic   | `franklin`            |
+| Helvetica         | `helvet`  (default)   |
+
+The navigation bar in the footer can be disabled using the `navbaroff` option.
+
+With the `kitgrid` option, the grid of the slides can be displayed.
+
+Example: `\documentclass[de,smallfoot, navbaroff]{CELbeamer}`
+
+## Title Slide
+-----------
+There are several layouts for the title slide. You can select them using frame options:
+
+| Layout              | Frame Option               |
+| ------------------- | ------------------------- |
+| green/white vertical| `title white vertical`     |
+| green/blue vertical | `title white vertical`     |
+| white horizontal    | `title white horizontal`   |
+| green horizontal    | `title green horizontal`   |
+
+The image on the title slide can be set with the `picture=` option. For vertical layouts, the image fits the height; for horizontal layouts, it fits the width.
+
+Additionally, for horizontal layouts, you can choose the color of the KIT logo.
+
+| KIT logo color | Frame Option             |
+| -------------- | ------------------------ |
+| colored        | `kitlogo=rgb`            |
+| white          | `kitlogo=white`          |
+| black          | `kitlogo=black`          |
+
+Example: `\begin{frame}[title white horizontal, picture=images/palladio_bauplan, kitlogo=black]`
+
+Special Slides
+--------------
+For tables of contents, you can specify the option `tableofcontents=<color>`, where `color` can be either `blue` or `green`. The table of contents will then be shown on a fully colored slide.
+
+There are also special layouts for divider slides with large images. You can select them using frame options.
+
+| Vertical image share: | Frame Option                   |
+| --------------------- | ------------------------------ |
+| 33%                   | `picture 33 vertical`          |
+| 50%                   | `picture 50 vertical`          |
+| 66%                   | `picture 66 vertical`          |
+| arbitrary             | `picture vertical=<value in %>`|
+
+The image is set with the option `picture=<path>`, where `path` must be given relative to the main document.
+
+Additionally, you can choose the color of the KIT logo in the footer, as it appears above the image.
+
+| KIT logo color | Frame Option             |
+| -------------- | ------------------------ |
+| colored        | `kitlogo=rgb`            |
+| white          | `kitlogo=white`          |
+| black          | `kitlogo=black`          |
+
+Example: `\begin{frame}[picture 66 vertical,picture=images/palladio_bauplan,kitlogo=black]{Slide with image}`
+
+Logo and Name of Department/KIT Faculty/Institute
+-------------------------------------------------
+
+The logo at the bottom right of the title slide can be set with the following command:
+
+`\grouplogo{mylogo}` (without file extension)
+
+To use your own logo, place the file (e.g., `mylogo.pdf`) in the `logos/` directory and adjust the command. If no logo should be included, use `\grouplogo{}`.
+
+The group name can be set with the following command:
+
+`\groupname{Software Design and Quality}`
+
+The group name appears in the footer at the bottom right. Long names will be wrapped into two lines. If the group name is left empty (`\groupname{}`), the full width of the footer will be used for author names and title.
+
+The default width of the group name is 89 mm. It can be changed with
+
+`\groupnamewidth{120mm}`
+
+which also adjusts the width of the author and title text field accordingly. Line breaks are possible with `\\`. Instead of two-line footers, the `smallfoot` option may be preferable.
