 ## Dockerfiles
 
-The `Dockerfile` is a multistage file which can build all three Dendrite
-images depending on the supplied `--target`. From the root of the Dendrite
-repository, run:
-
-```
-docker build . --target monolith -t matrixdotorg/dendrite-monolith
-docker build . --target polylith -t matrixdotorg/dendrite-monolith
-docker build . --target demo-pinecone -t matrixdotorg/dendrite-monolith
-```
+The `Dockerfile` builds the base image which contains all of the Dendrite
+components. The `Dockerfile.component` file takes the given component, as
+specified with `--buildarg component=` from the base image and produce
+smaller component-specific images, which are substantially smaller and do
+not contain the Go toolchain etc.
