-How to use artifacts passing between stages:
+In the following example, we define two jobs with artifacts, `build:osx` and
+`build:linux`. When the `test:osx` is executed, the artifacts from `build:osx`
+will be downloaded and extracted in the context of the build. The same happens
+for `test:linux` and artifacts from `build:linux`.
+
+The job `deploy` will download artifacts from all previous builds because of
+the [stage](#stages) precedence:
 
 ```
 build:osx:
   stage: build
-  script: ...
+  script: make build:osx
   artifacts:
     paths:
     - binaries/
 
 build:linux:
   stage: build
-  script: ...
+  script: make build:linux
   artifacts:
     paths:
     - binaries/
 
 test:osx:
   stage: test
-  script: ...
+  script: make test:osx
   dependencies:
   - build:osx
 
 test:linux:
   stage: test
-  script: ...
+  script: make test:linux
   dependencies:
   - build:linux
 
 deploy:
   stage: deploy
-  script: ...
+  script: make deploy
 ```
 
-The above will create a build artifacts for two jobs: `build:osx` and `build:linux`.
-When executing the `test:osx` the artifacts for `build:osx` will be downloaded and extracted in context of the build.
-The same happens for `test:linux` and artifacts from `build:linux`.
-
-The job `deploy` will download artifacts from all previous builds.
-However, only the `build:osx` and `build:linux` exports artifacts so only these will be downloaded.
