+This repository is public and contains shared workflows that are used
+in other builds. Each workflow takes a number of parameters and
+secrets as inputs. Parameters and secrets are documented in the
+respective workflows.
+
+At this point the the following workflows are available:
+
+- ```simple-container.yaml``` - One shot of build of a container through
+  a given Dockerfile.
+- ```go-binary.yaml``` - Builds a golang binary and uploads the binary
+  as artifact.
+- ```container-from-artifact.yaml``` - Builds and uploads a container from
+  a given artifact and a given Dockerfile.
+
+## Usage
+
+The workflows are used with in a master workflow through a workflow
+call, like below. Also see [build.yaml](https://gitea.ampenberger.com/campenbe/synauth/src/branch/main/.gitea/workflows/build.yaml)
+for an example
+
+  ```
+    ....
+    build-container:
+      uses: https://gitea.ampenberger.com/campenbe/workflows/.gitea/workflows/container-from-artifact.yaml@2025-10-01-1
+      with:
+        artifact_name: my_source_artifact
+        dockerfile: Dockerfile.small
+        package-name: cool-project
+        package-label: v1
+        version: v1-r1
+      secrets:
+        PASSWORD: ${{ secrets.PASSWORD }}
+        GIT_TOKEN: ${{ secrets.GIT_TOKEN }}
+  ```
+
+## Development
+
+To avoid caching issues always tag a new version and refer to the respective
+version with the tag in the consuming workflow.
