Not knowing exactly what car you have (you don't say model, year etc), but having replaced a fair few hoses myself, the way that works for me is usually as follows.
Make sure you have the correct hose before you start, try to check it visually, or try to hold the new hose near the old and compare. Make sure it has the same fittings and any other provisions (pressure sensor etc).
Remove whatever you have to that's in the way, things like intake etc that are 5 minute jobs can usually make things a whole lot easier, stuff that looks like it could be a bit longer, like coolant hoses or something, I try to work around as I don't want to dick around draining and topping up coolant.
Disconnect the lower part of the hose (catch all the fluid that comes out)
Disconnect the upper part of the hose, be ready for any fluid that might come out of there too.
Fit your new/replacement hose (If necessary use new copper washers on either sides of banjo fittings), I like to fit the hose, put the bolts in but leave the bottom loose.
Top up the fluid and get ready to tighten the bottom fitting, tighten it when fluid starts to come out (this helps bleed air out of the system).
Put everything back together and double check all bolts are tight.
Fire it up, turn the wheel lock to lock a few times and keep an eye on the fluid level, top up if needed.
