-# Gated Delta Net(GDN) kernel implementation in TileLang
+# Gated Delta Net (GDN) kernel implementation with TileLang
 
 ## Requirement
 
-### The Tilelang version for test is 0.1.5+17fafc1b3026d910a83eb8052fdf811ba56be0b1
-
-### We currently use triton=3.3.0 and FLA commit id=f03cb3ae for comparison
+- TileLang: `0.1.5+17fafc1b3026d910a83eb8052fdf811ba56be0b1`
+- Triton: `3.3.0` (used for comparison)
+- FLA: commit `f03cb3ae` (used for comparison)
 
 ## Get started
 
-### The common/chunk_delta_h.py implements the most critical forward kernel of GDN. It's a good start to understand the GDN logic and the tilelang optimization
