Reading Material for MLIR

I am new to this MLIR Community or Compiler Development in General. Have learnt Compilers in my UnderGrad but it is all about providing knowledge about overall working of compiler. During my Post Grad I thought of expanding my knowledgebase on compilers with some good project implementation.

I am pursuing a MLIR based project but due to scarce availability of reading materials or youtube videos on MLIR dialects and their implementation, I am finding it difficult to proceed. I would request some one from the community who could guide me to some good resources which would be sufficient enough to develop a know-how for a MLIR based dialect implementation. It would also surely help in MLIR community to grow and encourage the usage of MLIR compiler infrastructure in different domains.
