+### Obtaining and overriding `vendorHash` for `buildGoModule` {#buildGoModule-vendorHash}
+
+We can use `nix-prefetch` to obtain the actual hash. The following command gets the value of `vendorHash` for package `pet`:
+
+```sh
+cd path/to/nixpkgs
+nix-prefetch -E "{ sha256 }: ((import ./. { }).my-package.overrideAttrs { vendorHash = sha256; }).goModules"
+```
+
+To obtain the hash without external tools, set `vendorHash = lib.fakeHash;` and run the build. ([more details here](#sec-source-hashes)).
+
+`vendorHash` can be overridden with `overrideAttrs`. Override the above example like this:
+
+```nix
+{
+  pet_0_4_0 = pet.overrideAttrs (
+    finalAttrs: previousAttrs: {
+      version = "0.4.0";
+      src = fetchFromGitHub {
+        inherit (previousAttrs.src) owner repo;
+        rev = "v${finalAttrs.version}";
+        hash = "sha256-gVTpzmXekQxGMucDKskGi+e+34nJwwsXwvQTjRO6Gdg=";
+      };
+      vendorHash = "sha256-dUvp7FEW09V0xMuhewPGw3TuAic/sD7xyXEYviZ2Ivs=";
+    }
+  );
+}
+```
+
+### Overriding `goModules` {#buildGoModule-goModules-override}
+
+Overriding `<pkg>.goModules` by calling `goModules.overrideAttrs` is unsupported. Still, it is possible to override the `vendorHash` (`goModules`'s `outputHash`) and the `pre`/`post` hooks for both the build and patch phases of the primary and `goModules` derivation. Alternatively, the primary derivation provides an overridable `passthru.overrideModAttrs` function to store the attribute overlay implicitly taken by `goModules.overrideAttrs`. Here's an example usage of `overrideModAttrs`:
+
+```nix
+{
+  pet-overridden = pet.overrideAttrs (
+    finalAttrs: previousAttrs: {
+      passthru = previousAttrs.passthru // {
+        # If the original package has an `overrideModAttrs` attribute set, you'd
+        # want to extend it, and not replace it. Hence we use
+        # `lib.composeExtensions`. If you are sure the `overrideModAttrs` of the
+        # original package trivially does nothing, you can safely replace it
+        # with your own by not using `lib.composeExtensions`.
+        overrideModAttrs = lib.composeExtensions previousAttrs.passthru.overrideModAttrs (
+          finalModAttrs: previousModAttrs: {
+            # goModules-specific overriding goes here
+            postBuild = ''
+              # Here you have access to the `vendor` directory.
+              substituteInPlace vendor/github.com/example/repo/file.go \
+                --replace-fail "panic(err)" ""
+            '';
+          }
+        );
+      };
+    }
+  );
+}

 ## Using Ruby {#using-ruby}
 
-Several versions of Ruby interpreters are available on Nix, as well as over 250 gems and many applications written in Ruby. The attribute `ruby` refers to the default Ruby interpreter, which is currently MRI 3.1. It's also possible to refer to specific versions, e.g. `ruby_3_y`, `jruby`, or `mruby`.
+Several versions of Ruby interpreters are available on Nix, as well as over 250 gems and many applications written in Ruby. The attribute `ruby` refers to the default Ruby interpreter, which is currently MRI 3.3. It's also possible to refer to specific versions, e.g. `ruby_3_y`, `jruby`, or `mruby`.
 
 In the Nixpkgs tree, Ruby packages can be found throughout, depending on what they do, and are called from the main package set. Ruby gems, however are separate sets, and there's one default set for each interpreter (currently MRI only).
