I'm the one who create the documentations for our new task (Examine an existing and update it later on) because I'm the only who's currently doesn't have a task yet and my co-dev are currently fixing other project.

So I list some dependencies and information that will help us to understand this project, I also provide good sources which they can read, and also create a sample program which they can get from our repo and I also document it ( from config to crud)

So now they're (both my seniors) in same task with me but before they start I already give my documentations to them , and guest what, one of my senior appreciate my job and the other one who's saying he is the "team leader" and he doesn't even bother to read my documentations, and he prioritize other projects which he does not involve , and now he's creating his own sample program without reading any sources and copy pasting of some code from our project source code.
