+# Building Traffic Control Components
+
+## Build using docker-compose
+
+This is the easiest way to build all the components of Traffic Control; all requirements
+are automatically loaded into the image used to build each component.
+
+### Requirements
+- `docker` (https://docs.docker.com/engine/installation/)
+- `docker-compose` (https://docs.docker.com/compose/install/)
+
+### Steps
+
+From the top level of the incubator-trafficcontrol directory.  Use the BRANCH
+environment variable to specify the version of Traffic Control to build.   One
+or more components (with \_build suffix added) can be added on the command
+line:
+
+> $ BRANCH=1.8.x docker-compose -f infrastructure/docker/build/docker-compose.yml up traffic\_monitor\_build
+
+If no component names are provided here, all components will be built.
