-\section{Installation}
-\subsection{SD card preparation}
-\subsubsection{Partitions}
-Format the SD card with two new partitions:
-\lstsetbash
+\section*{Agricola Release HowTo}
+\subsection*{Create release branch}
+A push event to a \textit{release/...} named branch will create release
+candidates. These release candidates are deployed to agricola's project svn.
+(\texttt{http://dabsvn01.internal.novero.com/svn/\ \\
+0\_31X\_P0070\_agricola/trunk/development/software/\ \\
+releases/release\_candidate/})\\
+Checkout the new release branch:
 \begin{lstlisting}
-fdisk /dev/mmcblk0
+git checkout -b release/<release_name>
 \end{lstlisting}
-\begin{enumerate}
-\item Type \textbf{o} to erase all former partitions
-\item Type \textbf{p} to list all existing partitions
-\item Type \textbf{n}, then \textbf{p} to create the boot partition. Press
-\textbf{RETURN} to accept the first sector, then \textbf{+100M} for the
-last sector
-\item Type \textbf{t}, then \textbf{c} to set the partition type to FAT32
-\item Type \textbf{n}, then \textbf{p} to create the root partition. Press
-\textbf{RETURN} to accept the first sector, then \textbf{RETURN} for the
-last sector
-\item Type \textbf{w} to write the new partition table
-\end{enumerate}
-
-\subsubsection{File systems}
-Create the file systems for the new partitions:
+Prepare build variables in the \textit{variables} section of the build job
+file\\(\texttt{.gitlab-ci.yml} in agricola's root directory).
 \begin{lstlisting}
-mkfs.vfat /dev/mmcblk0p1
-mkfs.ext4 /dev/mmcblk0p2
+variables:
+  PRODUCT_NAME: "AG"
+  PRODUCT_VARIANT: "NA"
+#  PRODUCT_VARIANT: "EU"
+#  PRODUCT_VARIANT: "CN"
+  PROJECT_VERSION: "10"
+  SW_MAJOR: "1"
+  SW_MINOR: "2"
 \end{lstlisting}
-Create mount points and mount the new partitions:
+Push the new branch to the gitlab-server:
 \begin{lstlisting}
-mkdir boot
-mkdir root
-mount /dev/mmcblk0p1 boot
-mount /dev/mmcblk0p2 root
+git push --set-upstream release/<release_name> origin \
+release/<release_name>
 \end{lstlisting}

-sync
-mv root/boot/* boot
-\end{lstlisting}
-Enable ssh root login:
-\begin{lstlisting}
-vim root/etc/ssh/sshd\_config
-\end{lstlisting}
-Find \texttt{\#PermitRootLogin yes} and uncommend it
-\begin{lstlisting}
-PermitRootLogin yes
-\end{lstlisting}
-Unmount both partitions
-\begin{lstlisting}
-umount boot root
-\end{lstlisting}
