+# Concourse Tools
+
+This image is for building a container to run concourse tasks, which require various tools including: bosh-cli, awscli and curl. It uses bosh-cli-v2 as a base image and installs awscli on top using pip, and curl using apt.
+
+## Build locally
+
+```
+$ cd concourse-tools
+$ docker build -t concourse-tools .
+```
+
+## Run
+
+```
+docker run -it concourse-tools /bin/bash -c "bosh --version"
