 # RxJava 2 Operators Examples present in this sample project:
 
-* `Map` -> transform the items emitted by an Observable by applying a function to each item
+* `Map` -> transform the items emitted by an Observable by applying a function to each item. Blog: [RxJava Operator Map vs FlatMap](https://amitshekhar.me/blog/rxjava-map-vs-flatmap)
 * `Zip` -> combine the emissions of multiple Observables together via a specified function and emit single items for each combination based on the results of this function
 * `Filter` -> emit only those items from an Observable that pass a predicate test
-* `FlatMap` -> transform the items emitted by an Observable into Observables, then flatten the emissions from those into a single Observable
+* `FlatMap` -> transform the items emitted by an Observable into Observables, then flatten the emissions from those into a single Observable. Blog: [RxJava Operator Map vs FlatMap](https://amitshekhar.me/blog/rxjava-map-vs-flatmap)
 * `Take` -> emit only the first n items emitted by an Observable. [Blog for reference](https://amitshekhar.me/blog/rxjava-interval-operator)
 * `Reduce` -> apply a function to each item emitted by an Observable, sequentially, and emit the final value
 * `Skip` -> suppress the first n items emitted by an Observable
