Manual Installation

1. Download the latest release from GitHub, you need the files main.js, manifest.json, styles.css and trutzio-slides.zip
2. In Obsidian, open your vault's root folder in your file explorer
3. Navigate to the .obsidian/plugins directory, if it doesn't exist, create it
4. Extract the contents of the downloaded .zip file into a new folder within the plugins directory
5. Copy also the downloaded main.js, manifest.json, styles.css files into the newly created folder
6. Restart Obsidian or reload your vault
7. Go to Settings > Community Plugins and make sure "Safe Mode" is turned off
8. Click on Browse under Community Plugins, find Slides, and enable it

Element and Slide Attributes

You can customize the slide appearence and the revealing of elements within slides by using

• <!-- .slide: ... --> and
• <!-- .element: ... -->

markups as described here. The following example slide:

---

<!-- .slide: data-background="#ff0000" -->

# My Title

- Item 1 <!-- .element: class="fragment" data-fragment-index="2" -->
- Item 2 <!-- .element: class="fragment" data-fragment-index="1" -->

---

has a red background and the bullet points will incrementally appear in reverse order. Please use the cursor keys to reveal the items. More on fragments attributes here.

Links between slides

You can directly navigate between slides by giving the target slide an id and using this id as a link in the source slide. Here two example slides demonstrating navigation:

---
<!-- .slide: id="demo" -->
# Markdown Demo

This slide has id = "demo".

---

[go to slide with id "demo"](#/demo)

---

The first slide has id demo which is used as link (#/demo) from the second slide.

Embedding Code

You can embed code from different languages like Python, Java, etc. The following slide

---
# My Java Code

```java [1|3-7]
class Main {
  public static void main(String[] args) {
    int first = 10;
    int second = 20;
    // add two numbers
    int sum = first + second;
    System.out.println(first + " + " + second + " = "  + sum);
  }
}
\```
---

contains Java code with line numbers. Plese also note the revealing of the first line of code and after that the focus on the lines 3-7.

Speaker Notes

Within the presentation in browser press S to get an extra windows with actual and next slide containing also the speaker notes. At the end of a slide insert your speaker notes after Note: like in the example below:

---

Slide with speaker notes.

Note: This notes are only visible in the speaker notes window. Please press S within a presentation to open the speaker notes window.
---

Mathematical formulas with TeX

Within slides it is possible to use KaTex formulas between $$ signs. Below an example:

---
## Formulas with KaTex

$$F(x) = \int_{-\infty}^\infty f(x) e^{2 \pi i \xi} d\xi$$
