+# License Check Action
+
+A GitHub Action that validates source code files contain proper license and copyright headers.
+
+## Description
+
+This composite action scans the repository for source code files and verifies that each file contains either a "Copyright" statement or "Apache License" reference in its header. This helps ensure compliance with open-source licensing requirements.
+
+## Usage
+
+```yaml
+- name: Check License Headers
+  uses: ./.github/actions/license-check-action
+```
+
+### Example Workflow
+
+```yaml
+name: License Compliance
+
+on:
+  pull_request:
+  push:
+    branches:
+      - main
+
+jobs:
+  license-check:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Checkout code
+        uses: actions/checkout@v4
+
+      - name: Run license check
+        uses: ./.github/actions/license-check-action
+```
+
+## How It Works
+
+The action performs the following steps:
+
+1. Recursively finds all files in the repository (excluding `.git` directory)
+2. Filters files based on extension and name patterns
+3. Searches each file for the text "Copyright" or "Apache License"
+4. Reports any files missing the required license header
+5. Fails the check if any violations are found
+
+## Excluded File Types
+
+The following file types and patterns are automatically excluded from license checking:
+
+### Binary and Media Files
+- Images: `.png`, `.jpg`, `.gif`, `.ico`, `.svg`, `.PNG`
+- Fonts: `.eot`, `.ttf`, `.woff`
+- Documents: `.pdf`, `.docx`, `.graffle`
+- Archives: `.tar`, `.tar.gz`, `.jar`, `.oar`, `.csar`
+
+### Configuration and Data Files
+- `.json`, `.jsonld`, `.JSON`
+- `.xml`, `.yaml`, `.yml`, `.toml`
+- `.properties`, `.conf`, `.cfg`, `.cnf`, `.config`
+- `.csv`, `.db`, `.log`
+- `.txt`, `.md`, `.rst`
+
+### Certificate and Key Files
+- `.pem`, `.crt`, `.cert`, `.key`, `.csr`, `.der`
+- `.jks`, `.p12`, `.asc`, `.gpg`
+
+### Generated and Build Files
+- `.pb.go`, `.pb.gw.go`, `*_pb2.py`, `*_pb2_grpc.py`
+- `.pb.h`, `.pb.cc`
+- `.pyc`, `.bin`
+- `go.mod`, `go.sum`
+- `.lock` files
+
+### Special Files
+- `Dockerfile`, `Dockerfile.*`
+- `Makefile`, `Makefile.*`
+- `README`
+- `*ignore` files (e.g., `.gitignore`, `.dockerignore`)
+- `*rc` files (e.g., `.bashrc`, `.npmrc`)
+
+### Excluded Directories
+- `vendor/`
+- `conf/`
+- `git/`
+- `swagger/`
+- `docs/`
+
+## Troubleshooting
+
+### False Positives
+
+If files are incorrectly flagged as missing license headers:
+
+1. Verify the file contains either "Copyright" or "Apache License" text
+2. Check that the text appears in a comment format appropriate for the file type
+3. Ensure there are no encoding issues preventing text detection
