 \chapter{Monero usage and storage best practices}
+Ease of use is one of the critical aspects of every cryptocurrency and although Monero can offer a wide range of anonymity features it has to be usable and user-friendly in order to be used by a substantial margin of people. Usability in Monero is a long-term topic that brings out active discussion \cite{monerolang2018}.
+
+Following scenarios represent secure and easy to use instructions for a new Monero user.
+
+\section{Generating the keys}
+The software way means using the official client CLI and GUI wallet available at \url{https://getmonero.org/downloads/} by which user generates the wallet keys. Created keys are after generation saved directly into the memory of the device unless specified otherwise. 
+
+Note that the security of this task depends on the origin of the software, delivery chain trust, and the users' operating system. Monero CLI and GUI binaries can be edited, and the app itself does not call any hash checking to alert the user of the unauthorized change. 
+
+Although SHA256 has is provided on the website, the user is not instructed to check the hashes beforehand with tools like PowerShell and \texttt{Get-FileHash ./monero-wallet-gui-original.exe | Format-List} command \cite{pialphapialphagammaiotaacutealphanunualpharhoovarsigma2016study}.\\

+
+There are also alternative approaches to key generation like an offline javascript based monero-wallet-generator that is available at \url{https://github.com/moneromooo-monero/monero-wallet-generator}.\\
+\newpage
+Hardware way is considered to be in the development, but Monero compatibile devices like Ledger Nano S are already on the market. The way how keys are generated in hardware wallets varies on firmware included in each device. 
+
+In general, the wallet is required to have Monero app installed from vendors app catalog. Keys are generated on the hardware device within the app itself and user can only export private view key from the device to view the balance in full CLI/GUI client.
