+# JSON Validation Scripts
+
+Utility scripts for validating JSON files and checking for duplicate package names between Google and Community privileged browser lists.
+
+## Usage
+
+### Validate a JSON file
+
+```bash
+python validate_json.py validate <json_file>
+```
+
+### Check for duplicates between two JSON files
+
+```bash
+python validate_json.py duplicates <json_file1> <json_file2> [output_file]
+```
+
+If `output_file` is not specified, duplicates will be saved to `duplicates.txt`.
+
+## Running Tests
+
+```bash
+# Run all tests
+python -m unittest test_validate_json.py
+
+# Run the invalid JSON test individually
+python -m unittest test_validate_json.TestValidateJson.test_validate_json_invalid
+```
+
+## Examples
+
+```bash
+# Validate Google privileged browsers list
+python validate_json.py validate ../../app/src/main/assets/fido2_privileged_google.json
+
+# Check for duplicates between Google and Community lists
+python validate_json.py duplicates ../../app/src/main/assets/fido2_privileged_google.json ../../app/src/main/assets/fido2_privileged_community.json duplicates.txt
+```
