+Dockerfiles
+============
+
+The docker images for Eclipse CDT's [Jenkins instance](https://ci.eclipse.org/cdt/) are stored at [quay.io](https://quay.io/organization/eclipse-cdt)
+and built using the following scripts. The individual directories below this one contain Dockerfiles which contain a little more information. Note that
+the split between the Dockerfiles is somewhat arbitrary and historical. Only the cdt-infra-eclipse-full image is known to be referenced outside
+of the cdt repo.
+
+build-images.sh
+===============
+
+Builds the images locally. A download of [Xcode_9.4.1.xip](https://download.developer.apple.com/Developer_Tools/Xcode_9.4.1/Xcode_9.4.1.xip) (visit [here](https://developer.apple.com/download/more/) first to logon to Apple if needed) is needed to do a complete build. To save on rebuild times, the xip can be removed from the directory to use the cached cdt-infra-build-macos-sdk image.
+
+deploy-images.sh
+================
+
+Builds images (from cache), uploads them to quay.io/eclipse-cdt namespace and then
+updates all the Jenkinsfile and yaml files to refer to these new images.
+
+Using the docker images
+=======================
+
+The docker images exist mostly for use in Jenkins, see the [pod templates](https://github.com/eclipse-cdt/cdt/blob/main/jenkins/pod-templates).
+
+They can be used to recreate a consistent environment in other cases too. For example, you can run a full build on a machine that does not already have the tools by using docker:
+
+```
+docker run --rm -it -v $(git rev-parse --show-toplevel):/work -w /work/$(git rev-parse --show-prefix) --cap-add=SYS_PTRACE --security-opt seccomp=unconfined quay.io/eclipse-cdt/cdt-infra-eclipse-full:latest COMMAND HERE
+```
+
+For examples of the above in practice, see [cdt-gdb-adapter's integration tests readme](https://github.com/eclipse-cdt/cdt-gdb-adapter/blob/master/src/integration-tests/README.md) and the native section of [CDT's readme](https://github.com/eclipse-cdt/cdt/blob/main/BUILDING.md#native)

+Building GDBs in a separate image
+=================================
+
+The GDBs take a long time to build and it is very inconvenient to have to build them
+because something else in a Docker file has changed. Therefore, this image *only*
+builds the GDBs using the download-build-gdb.sh script.
+
+Other images can then use these prebuilt GDBs by copying them to their image.
+
+For example, to copy all the GDBs use this line:
+
+```
+COPY --from=cdt-infra-all-gdbs:ubuntu-18.04 /shared/common/gdb/gdb-all /shared/common/gdb/gdb-all
+```
+
+Or, to copy a specific version only, do this:
+
+```
+# Copy install directory
+COPY --from=cdt-infra-all-gdbs:ubuntu-18.04 /shared/common/gdb/gdb-all/install/gdb-8.2.1 /shared/common/gdb/gdb-all/install/gdb-8.2.1
+# Copy versioned links
+COPY --from=cdt-infra-all-gdbs:ubuntu-18.04 /shared/common/gdb/gdb-all/bin/gdb.8.2 /shared/common/gdb/gdb-all/bin/gdb.8.2
+COPY --from=cdt-infra-all-gdbs:ubuntu-18.04 /shared/common/gdb/gdb-all/bin/gdb.8.2.1 /shared/common/gdb/gdb-all/bin/gdb.8.2.1
