Latex is is a document preparation system for high-quality typesetting. It is most often used for medium-to-large technical or scientific documents but it can be used for almost any form of publishing. It was invented by Don Knuth in 1970 to publish a programming book.
First of all, we can install Latex by using the Software Center of Fedora 26. You might do click on Activities, a second click on Software and do a final click on the magnifying glass icon to write Latex on the bar to display TeXstudio:
Make sure you have installed it successfully. This is how it will look like:
Now open it and you will see three sections at the beginning. Click on File/New to start a new project. Another way is by clicking on the Blank Page icon:
To run the “hello world” example, we can click on the Green Play button and to see how our job looks like, click on the magnifying glass icon.
To create a document, we need to define the class as the sequence of characters showed in the following picture; as well to mark the begin and end of our content, in this case, the sentence “Hello world!”
Now let’s work with paragraphs and spaces between the lines. You can work with the following commands and see what you got after compiling: 
By default, the paragraph is indented and if you do not want it in that way, please write \noindent. To start another paragraph, left a line in blank or write \\ and the new paragraph will start it with no indentation. To set a space, use \hspace, and the \pagebreak will leave the page in blank until the next one.
To format the fonts, try this code and check the different features you have:
You can set font styles such as bold, italic, underline and huge to make the letter huge, are shown in the document above.
An example of using images, columns and links is shown below: 
In order to make the image visible use the \usepackage{graphicx}, as well as the columns are set with \usepackage{multicol} and links with hyperref.
Now I will share the code of a syllabus for my class:
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{color}

{\tiny * Tanto para los feriados y la Semana de la Universidad se dejaran trabajos domiciliarios}
\noindent \textbf{Evaluación}
\begin{itemize}
\item Se establecen en total 4 practicas y se eliminara la práctica con menor nota. En total se promediaran 3 practicas para tener la nota de Promedio de Prácticas (PP).
\item Se tomaran en total 4 notas de labotario y se eliminará la práctica con menor nota. En total se promediaran 3 notas de laboratorio para tener la nota de Promedio de Laboratorio (PL).
\item Se tomará un examen parcial (EP), un examen final (EF)
\item Se tomará un examen sustitorio (ES) que sustituirá la nota más baja, sea del EF o del EP.
\item La nota final (NF) se obtendrá como se indica en la ecuación [1]
\begin{equation}
NF = (PP + PL + EF + EP )/4
\end{equation}
\end{itemize}
\noindent \textbf{Consideraciones}
\begin{itemize}
\item Tiempo de tolerancia de ingreso a clases: 15 minutos
\item La evaluación es contante, se reflejará todo el trabajo de los alumnos y de la profesora Julita Inca Chiroque, en el Aula Virtual Insitucional de la UNI.
\item A solicitud de la Escuela, se estará teniendo en cuenta la asistencia a las clases y se registrará en el aplicativo de ORCE.
\item Si se detecta plagio en los trabajos domiciliarios se colocará 0A en el promedio de Practicas o de Laboratorio, según corresponda.
\end{itemize}
