 ### Testing
 
-#### Dgraph
+Dgraph employs a ~~complex~~ sophisticated testing framework that includes extensive test coverage. 
+Due to the comprehensive nature of these tests, a complete test run can take several hours, depending
+on your hardware. To manage this complex testing process efficiently, we've developed a custom test 
+runner implemented in Go, which resides in the ./t directory. This specialized runner provides enhanced 
+control and flexibility beyond what's available through standard Go testing commands.
+
+For dependencies, runner flags and instructions for running tests on non-linux machines, see 
+the [README](t/README.md) in the [*t*](t) folder.

 1. Change directory to t directory. 
 2. If all packages need to be tested, run
       make test
