-## Building static Linux binaries with Docker
+`build-release` is the entry point to generate the binaries and Breakpad symbol files for a given
+platform. Currently the working configurations are Linux hosts for Linux, NaCl, or Windows
+targets and binaries and MSYS2 for Windows targets. For Linux, it is difficult to set up the
+required static libraries, so the Docker build is especially useful.
+
+## Building in docker
 
 For the `rev` argument, you should use a tag or a commit hash, rather than a branch
 name, in order to avoid false caching.
 
+It is recommended to check the results with [validate-release](https://github.com/Unvanquished/validate-release),
+e.g. `../validate-release/validate-release linux-amd64.zip`.
+
+### Build static Linux binaries
 ```
 # Build
-docker build -t unvrel . --build-arg=rev=3173f3307
+docker build -t unvrel . --build-arg=rev=3173f3307 --build-arg=targets=linux-amd64
 # Get outputs
 docker create --name tmp unvrel
 docker cp tmp:/Unvanquished/build/release/linux-amd64.zip .
 docker rm tmp
