 # uni-tex-template
 
 The Latex Template for my University Assignments
+
+## Overview
+- Inclusion of all required packages and configuration
+- Customized Header with all required information and fields for assignment submission
+- Single-File config for simplicity
+
+## Usage
+This Template works for 1 to 4 credited Authors.
+
+The default config is of the 2-Author variant. The additional 2 configurations are clearly commented in the Preamble of the document.
+
+To use a 1, 3 or 4 Author configuration, do as follows:
+
+1. Comment out the enabled config as follows:
+```tex
+% Default config
+% \lhead{[Subject Name]]\\[Term]}
+% \chead{\bfseries{\vspace{0.5\baselineskip}[Assignment Title]}}
+% \rhead{[Name of 1st Author], [Matr. Nr of 1st Author]\\[Name of 2nd Author], {Matr. Nr of 2nd Author]}}
+```
+2. Choose Your desired configuration and uncomment it as follows:
+    - Single-Author:
+        ```tex
+        % UNCOMMENT TO USE: Config for Single Author
+        \lhead{\vspace{0.5\baselineskip}[Assignment Title]}
+        \chead{\bfseries{[Subject Name]\\[Term]}}
+        \rhead{\vspace{0.5\baselineskip}[Name of 1st Author], [Mtr. Nr of 1st Author]}
+        ```
+    - 3- or 4-Authors:
+        ```tex
+        % UNCOMMENT TO USE: Config for 3-4 Authors
+        \lhead{[Name of 1st Author], [Matr. Nr of 1st Author]\\[Name of 2nd Author], [Matr. Nr of 2nd Author]}
+        \chead{\bfseries{\vspace{0.5\baselineskip}HL-BPR Praktikum SS25\\Blatt 06}}
+        \rhead{[Name of 3rd Author], [Matr. Nr of 3rd Author]\\[Name of 4th Author], [Matr. Nr of 4th Author]}
+        ```
+        *Note*: For this variant with a 3 Author config, simply remove the last part of the `\rhead` tag with the linebreak!
+3. Recompile!
