 To keep things consistent, we have a docker image to run all tests. **These are the same tests ran on the pull request checks**.
 
+Note that all testing docker container binds a couple of ports to the host machine for your convince. The ports are: 
+* `9500` - Shard 0 RPC for a validator
+* `9501` - Shard 1 RPC for a validator
+* `9599` - Shard 0 RPC for an explorer
+* `9598` - Shard 1 RPC for an explorer
+* `9799` - Shard 0 Rosetta (for an explorer)
+* `9798` - Shard 1 Rosetta (for an explorer)
+* `9899` - Shard 0 WS for an explorer
+* `9898` - Shard 1 WS for an explorer
+> This allows you to use curl, hmy CLI, postman, rosetta-cli, etc... on your host machine to play with or probe the localnet that was used for the test.

+### Rosetta tests
+To run this test, do:
+```bash
+make test-rosetta

+This test starts a localnet (within the Docker container), **ensures it reaches a consensus**, and runs the Construction & Data API checks using the [rosetta-cli](https://github.com/coinbase/rosetta-cli).
+This test also acts as a preliminary integration test (more through tests are done on the testnets).
+> The config for this test can be found [here](https://github.com/harmony-one/harmony-test/blob/master/localnet/configs/localnet_rosetta_test_s0.json) & [here](https://github.com/harmony-one/harmony-test/blob/master/localnet/configs/localnet_rosetta_test_s1.json)

+Similar to the RPC tests, if you wish to debug further with the localnet after the tests are done, open a new shell and run:

+make test-rosetta-attach
