+## Reusable Workflows
+
+### Docker Build & Push
+
+This reusable workflow builds a Dockerfile located in the root of the project, pushes the new Docker image to an ECR Registry, and optionally updates ECS task definitions for services or scheduled tasks.
+
+For scheduled tasks, the caller repository can define runtime overrides under `.config/`:
+
+- Scheduled tasks must provide `.config/<execution-name>.json`.
+
+The file is merged with the current active task definition before the image tag is updated, so the application repository owns the scheduled-task runtime fields without Terraform managing them.
+
+#### Usage
+
+To use this workflow, call it from another workflow file as shown in `.github/workflows/dev-build-upload.yml`:
+
+```yaml
+jobs:
+  build-push:
+    uses: gsoftcolombia/github-actions/.github/workflows/docker-build-upload.yml@main
+    with:
+      AWS_DEFAULT_REGION: ${{ vars.AWS_DEFAULT_REGION }}
+      AWS_ROLE_TO_ASSUME: ${{ vars.AWS_ROLE_TO_ASSUME }}
+      ECR_REPOSITORY: ${{ vars.ECR_REPOSITORY }}
+      NAME_PREFIX: ${{ vars.NAME_PREFIX }}
+      
+      DEPLOY_SCHEDULED_TASK: true
+      EXECUTION_NAME: ${{ vars.EXECUTION_NAME }}
+      
+      DEPLOY_ECS_SERVICE: false
+      SERVICE_NAME: ${{ vars.SERVICE_NAME }}
+      ECS_CLUSTER_NAME: ${{ vars.ECS_CLUSTER_NAME }}
+      ECS_DEV_DEPLOY: false
+```
+
+#### Required Variables
+
+- `AWS_DEFAULT_REGION`: AWS region (available in all /gsoftcolombia projects).
+- `AWS_ROLE_TO_ASSUME`: ARN of the role for aws-actions to assume.
+- `ECR_REPOSITORY`: ECR Repository Name.
+- `NAME_PREFIX`: Prefix of the task definition in AWS.
+
+#### Optional Inputs
+
+- `DEPLOY_SCHEDULED_TASK`: Set to true to deploy scheduled tasks.
+- `EXECUTION_NAME`: Suffix for scheduled task definitions (can be a list separated by ';').
+- `DEPLOY_ECS_SERVICE`: Set to true to deploy an ECS service.
+- `SERVICE_NAME`: Name of the ECS service.
+- `ECS_CLUSTER_NAME`: Name of the ECS cluster.
+- `ECS_DEV_DEPLOY`: Set to true to deploy to dev environment.
+
+For more details, see the workflow file at `.github/workflows/docker-build-upload.yml`.
