 The `build` target is split into two sub-targets:
 
-- `make backend` which requires [Go 1.17](https://go.dev/dl/) or greater.
+- `make backend` which requires [Go Stable](https://go.dev/dl/), required version is defined in [go.mod](/go.mod).
 - `make frontend` which requires [Node.js LTS](https://nodejs.org/en/download/) or greater and Internet connectivity to download npm dependencies.
 
 When building from the official source tarballs which include pre-built frontend files, the `frontend` target will not be triggered, making it possible to build without Node.js and Internet connectivity.
