Olly Debug Tutorial?

Does anyone know a good recomendation for one.  Only time I ever used a stepping debugger to any extent was years ago with TASM.  I forget a lot of the details.  Understanding what I'm seeing in disassembled code is one of my main goals in learning masm.  I downloaded Olly Debug, but the doc file with it isn't really a tutorial.  That's why I'm asking.  I did a search and found a lot of results, but most seemed geared towards fokks with nefarious ends, which isn't where I'm coming from.

Unfortunately there is probably a lot of tutorials related to doing specific things with olly and not so much as basic how to or overviews.

I did find a few tutorials that appear to be mostly covering the basics of usage, without getting into any specifics like you mentioned. Hopefully they might help:

Tutorial #2 : Intro To Olly Debug - http://octopuslabs.io/legend/blog/archives/31.html
Tutorial #3: Using OllyDBG, Part 1 - http://octopuslabs.io/legend/blog/archives/115.html
Tutorial #4: Using Olly, Part 2 - http://octopuslabs.io/legend/blog/archives/258.html

The rest of the tutorials listed are more specific and dont relate to general usage, but from looking at those three, they appear quite well documented and laid out, hopefully enough to get you started.

Some handy keys to remember:

Program reset             Ctrl + F2

Thanks fearless.  That'll definitely get me started.

Fred,

Attached is the only manual I ever found. Most of the time I just use F7-F9, though :P

Specifically what 1-58 articles are you referring to?
The links posted by Mikl__ (years ago) all seem to be referencing "cracking" (otherwise known as reverse engineering) at least those in Spanish - Discussion of which is not allowed here.  :eusa_naughty:
:azn:

I"m not going to discuss it, dont worry
I'm looking for fresh links that were given here years ago (2016) but for some reasons links are dead
