 ### Production
 
 Building requires that [Docker](https://www.docker.com/get-docker) is installed
-on your system.  The build is made from code in the commit at `HEAD`, not from the files in the working tree.
+on your system.
 
-Build and run the app.
+Build the app:
+
+The first argument is a commit for Voyager (e.g., the tag `0.4.3`).  Optional
+arguments (such as `--platform`) must come afterwards.
+
+```bash
+yarn run build 0.4.3 --platform={darwin|win32|linux}
+```
+
+You can specify a commit hash for the version of Gaia to use if it has been prebuilt:
+
+```bash
+GAIA_COMMIT=decb23bed0179244e4f42d697dcd4bf759200a2d yarn run build 0.4.3
+```
+
+
+Run the app.
 ```bash
-yarn run build --platform={darwin|win32|linux}
 open builds/Cosmos-{platform}-x64/Cosmos.app
 ```
 
 When you are testing the build system you can skip the repackaging of the JS files.
 ```bash
-$ yarn run build --platform=darwin --skip-pack
+$ yarn run build 0.4.3 --platform=darwin --skip-pack
 ```
