+# Dockerfile
+
+## Definitions
+
+There are two `Dockerfile`s, one for each step of execution set in
+the [definitions document][definitions-doc].
+
+## Containers
+
+- Build
+
+Defined in `Dockerfile.build`
+
+Has installed every program that is needed to build the code.
+Gets the source, install the dependencies and makes the final binary
+of our app.
+
+The reason for us to have a container just for the building process is
+that it demands lots of programs and dependencies to set up the Go
+environment and build everything, which aren't needed in the server for
+our app to run. Without it, the container for the running process would
+be huge, full of useless binaries and softwares.
+
+- Run
+
+Defined in `Dockerfile.run`
+
+This is the container that will run in the servers. Contains nothing,
+but our app and what it need to make it run.
