---
- All relevant content of README.md files was migrated to docs/ section in their respective section.
- These README files has been deleted (4 files)
- All README.md files (additional to the project's root and docs/) have been edited.
---
- Both files build-docker-images/README.md and docs/dev/build-image.md have almost same content, so it was discarded the README file
- As the directory and docker image are going to be disused, the certs-gen documentation contents of indexer-certs-creator/README.md was not mig>
- The 'bash' command added to the docs/dev/build-image.md was removed
- Added workflow usage docs file to the the SUMMARY.md file
---
- Removed '$' parameter and added 'bash' to all markdown code blocks headings (```)

+# Workflow usage
+
+The Procedure_push_docker_images.yml workflow builds and pushes multi-architecture Docker images (amd64/arm64) of Wazuh core components (Indexer, Manager, Dashboard, and Agent) to container registries.
+
+## Input Parameters
+
+| Parameter | Description | Default | Required |
+|-----------|-------------|---------|----------|
+| `image_tag` | Docker image version tag | `5.0.0` | Yes |
+| `docker_reference` | Branch/tag to build from | - | Yes |
+| `revision` | Package revision number | `1` | Yes |
+| `reference` | Dev reference (for pre-release builds) | `latest` | No |
+| `id` | Workflow run identifier | - | No |
+| `dev` | Enable development mode (adds `-dev` suffix) | `false`/`true` | No |
+
+## Development vs Production Mode
+
+**Development Mode** (`dev: true`):
+
+- Pushes to AWS ECR (Elastic Container Registry)
+- Uses pre-signed S3 URLs for packages
+- Generates dynamic `artifact_urls.yml` from S3 bucket
+- Adds development reference to image tags
+- Authenticates via AWS IAM role
+
+**Production Mode** (`dev: false`):
+
+- Pushes to Docker Hub
+- Uses public package repositories
+- Authenticates with Docker Hub credentials
+- Supports version stages (rc, beta, etc.)
+
+## Build Process
+
+1. **Artifact Resolution**:
+   - Dev mode: Creates pre-signed URLs for all Wazuh packages from S3
+   - Prod mode: Uses packages from public repositories
+
+2. **Multi-architecture Build**:
+   - Uses Docker Buildx with QEMU for cross-platform builds
+   - Builds for `linux/amd64` and `linux/arm64`
+   - Leverages `build-images.yml` for build configuration
+
+3. **Image Publishing**:
+   - Tags images appropriately based on mode
+   - Pushes to the configured registry
+   - Generates .env file with build metadata
+
+## Log Collection Feature
+
+When tests fail, the workflows automatically collect and display relevant logs to help diagnose issues quickly.
+
+This is implemented via two scripts, executed depending on the test setup:
+Single-node: `single-node-log-check.sh`
+Multi-node: `multi-node-log-check.sh`
+
+Capabilities include:
+
+- Collects ERROR, WARNING, and CRITICAL messages from all nodes.
+- Automatically gathers logs on test failures for faster debugging.
+
