Personally I have &quot;knowlede base&quot; document where are useful hints, commands and step-by-step guides how to do something (like: configure&#x2F;code&#x2F;export&#x2F;filter etc.).<p>Other text file contains useful links with other&#x27;s step-by-step guide founded on internet.<p>Github is interesting idea since it&#x27;s available from my personal and working laptop. Till now i have used google docs&#x2F;gmail draft messages.
