Learning Agile and Scrum on my own, looking for advice, resources, insights

I haven't had the chance to work both in groups of developers nor in groups of developers working under Scrum or Agile work philosophies/frameworks/methodologies.

What advice/course/selected-reading can you give me for learning this on my own? Keeping in mind that I want to be prepared for the time when I get into a team working under those methodologies.

Thanks in advance.

I'm sharing here my findings on this topic, for anyone's use:

Eventually everyone gets to a bastardized version of scrumfallban, this is for a lot of reasons, but mostly your goal is to get things done.

Any purists are going to give you ( ironically ) rigid advice about agile that will likely fail

You can lookup techniques like SPIDR and INVEST as well.

Also, imho agile is about not being afraid to tell the truth. This is the hardest part imho

I literally said in a standup the other day, I’m having trouble focusing, I think it’s the medication I’m on, but I need to take it easy for a few sprints until I get this under control.

Great insights. Thanks.

And yes, we are only humans after all. That's some valuable information to share with any team.

About Agile:

http://agilemanifesto.org/ This seems to be the very first official site, dating back to 2001.

https://www.agilealliance.org/communities/ I'm not sure if the Signatories of the manifesto are related to this site, but it is a really comprehensive one with lots and lots of good resources for learning and getting involved.

You might want to look at feature selector theories too, for instance MoSCoW
