How to become a member of the OpenSource project (technical issues)?

Question

open source

Hello!
I work in a web studio. There are many tasks, but they have long become a routine and do not bring pleasure. By specialization, I am a Back-end developer, I write in PHP, and specifically in the Yii2 framework. I also write simple console applications for Linux just for fun.
The problem is that in our studio I am the only back-end developer and I have no one to share my experience with or stir up the project with. Everyone advises to connect to OpenSource projects on GitHub, of which there are a myriad. What stops me is complete ignorance of the OpenSource kitchen and a rather superficial understanding of GitHub, although I actively use Git, but only in my private turnips on Bitbacket (I save =) ).
I would like to know from those who are already involved in similar projects, how and on what principles to send pull requests, throw an issue, connect with other developers. In order not to step on a rake and not annoy the community with obvious mistakes.
Ideally, I would like to somehow cooperate with people who have an OpenSource project and who need help with development. Which, in turn, would help me with an understanding of how it all works and who could always be consulted (not on code issues, but on interaction issues).
Thanks in advance.

Answer 1

There is a bug that has not yet been issued - write an issue. We managed to fix it ourselves - make out a PR and indicate that it fixes such and such an issue. If you annoy, ideally you will be gently pointed out.
In my opinion, obviously, a lot of text, but what is the essence of the question is not clear.
PS I have a bunch of open projects and I also participate in a bunch of different ones.

It seems that you can make some kind of your bike. Or not a bike.
Open source does not mean that you need to be connected to the team. This also means that you can act as the author yourself.
