\Large A Tutorial for Poster Creation with Tcolorbox

Welcome to the poster tutorial!
\tcbline
We start at the very begin with an empty poster.\par\medskip
In this tutorial, we use A3 sized paper in landscape format which can
be set up with the \texttt{geometry} package.
Naturally, we need the \texttt{tcolorbox} package with at least the
\texttt{poster} library loaded.\par
At begin, we only choose the number of columns (4) and rows (5) and
we display a help grid.\par\medskip

\begin{posterboxenv}[blankest]{column=2,span=2,above=bottom}
\begin{guide}
Now, we put in some fancy settings to the poster \texttt{coverage}.\par
Also, some more packages are loaded for the future poster content.

\begin{guide}
It is time to fill boxes into the \texttt{poster} environment.
This is the most crucial part of your poster creation, because you have
to decide about the general contents and the base design.\par
But, as you can see in the listing below, the boxes are placed with
relative positions to each other and the sizes are able to change
automatically.

The \texttt{project} box is made breakable. Note the two parts
\texttt{project1} and \texttt{project2} where the second part is
denoted by a placeholder.

As next step, we choose some nice settings for all the boxes. These
global settings are applied using the \texttt{boxes} option of
the poster.\par
Also, we do not need the auxiliary frame lines anymore and we set
\texttt{showframe=false}.
