-# Build
+# Build new image
 
 As an example we build a new version (2.2.0) of the leapcode/ruby image:
 
-    cd ruby
-    docker build -t leapcode/ruby:2.2.0 .
+## Find latest version
 
-# Push images
+I.e. look at the tags at https://hub.docker.com/r/leapcode/ruby/tags/
+
+    VERSION='2.2.0'
+    IMAGE='ruby'
+    cd $IMAGE
+    docker build -t leapcode/${IMAGE}:${VERSION} .
+
+## Push images
 
     docker logout
     docker login -u leapcode
-    docker push leapcode/ruby:2.2.0
-    docker tag leapcode/ruby:2.2.0 leapcode/ruby:latest
-    docker push leapcode/ruby:latest
+    docker push leapcode/${IMAGE}:${VERSION}
+    docker tag  leapcode/${IMAGE}:${VERSION} leapcode/${IMAGE}:latest
+    docker push leapcode/${IMAGE}:latest
