I am trying to study the moduli of holomorphic vector bundles fast and I'm primarily interested to understand:

1) Why and were the stability is important. 2) How are the construction methods. 3) some examples. (especially the case of vector bundles on curves)

I was looking for some references but I could not find any reasonable source online. I have the base for that and I don't want some thing very long and full of details.

I just want to see all the ideas very clearly without to much details.

Please tell me if you know any lecture note or book which contains this stuff.

Thanks in advance
