+
+**Conform** is a tool for building projects in a flexible and reliabale manner.
+
+The key features of Conform are:
+-   **DRY**: Templatized multi-stage Docker builds.
+-   **Hygienic**: Builds run in Docker.
+-   **Fast**: Leverages Docker caching, building only what has changed.
+
+Getting Started
+---------------
+Create a file named `conform.yaml` with the following contents:
+```yaml
+metadata:
+  repository: example
+scripts:
+  init : |
+    #!/bin/bash
+
+    set -e
+
+    echo "Hello, world!"
+templates:
+  build: |
+    FROM alpine:latest as build
+    RUN echo "Run your build here!"
+    RUN touch artifact
+  test: |
+    FROM alpine:latest as test
+    COPY --from=build artifact .
+    RUN echo "Run your tests here!"
+  image: |
+    FROM scratch as image
+    RUN echo "Deply your image here!"
+    COPY --from=build artifact .
+rules:
+  all:
+    templates:
+      - build
+      - test
+      - image
+
+```
+
+In the same directory, run:
+```
+$ conform enforce all
+```
+> **Note:** Conform is still under design. The YAML layout is subject to change.
