Anyone who would still find this useful if updated?

This guide link is messed up, is there an alternate way to get the user guide? I get the message on Firefox and MS Edge:
Link Blocked!
This link has been flagged as potentially malicious.

My biggest problem is that when I grab something to go into edit mode (or even just placing it originally) it slightly moves off the axis like a fraction of a degree. When I'm mirroring and extruding then it multiplies the issue and takes me a long time just to get it straightened out and still ends up not lined up on a rotation. If I try to use the precision tool it changes in 5 degrees when I toggle the snap feature, but it is like < 1 degree off so it just moves it and is still of kilter. Is there a way to lock in while you are selecting, or a way to have it snap exactly to an axis, or better yet snap to align with all three axis when being placed.

ty!

Link needs to be updated
