 ## Gas reports
 
-These gas reports were produced using the `0.8.19` version of the Solidity compiler, specifically for the
-[`0.3.0`](https://github.com/0x90d2b2b7fb7599eebb6e7a32980857d8/secp256r1-verify/releases/tag/v0.3.0) version of the
+These gas reports were produced using the `0.8.19` version of the Solidity compiler (with 100k optimizer runs),
+specifically for the
+[`0.3.1`](https://github.com/0x90d2b2b7fb7599eebb6e7a32980857d8/secp256r1-verify/releases/tag/v0.3.1) version of the
 library. The library version corresponds to commit
 [5436b12](https://github.com/0x90d2b2b7fb7599eebb6e7a32980857d8/secp256r1-verify/commit/5436b12f40e3cb5d0f593709067b22054e4164b8).
 
+> ℹ️ If you import the library into your project, we strongly recommend you to enable the optimizer with 100k in order
+> to have the best gas consumption.

 Although the prerequisites for implementing this approach are more complex, the gas cost for the verification process is
 over three times less expensive than the traditional method.
