+# validate-collections-yaml
+
+This script validates YAML collection files against a predefined schema to ensure their integrity.
+
+## Prerequisites
+
+- Python 3.x installed on your system.
+
+## Running in a Virtual Environment (Recommended)
+
+Using a virtual environment isolates dependencies and prevents conflicts.
+
+1. **Create a virtual environment:**
+
+   ```bash
+   python3 -m venv ./scripts/validate-collections-yaml/.venv
+   ```
+
+2. **Activate the virtual environment:**
+
+   ```bash
+   source ./scripts/validate-collections-yaml/.venv/bin/activate
+   ```
+
+3. **Install dependencies:**
+
+   ```bash
+   python3 -m pip install -r ./scripts/validate-collections-yaml/requirements.txt
+   ```
+
+4. **Run the script:**
+
+   ```bash
+   python3 ./scripts/validate-collections-yaml
+   ```
+
+## Running Globally
+
+Running the script globally is less recommended due to potential dependency conflicts.
+
+1. **Install dependencies:**
+
+   ```bash
+   python3 -m pip install -r ./scripts/validate-collections-yaml/requirements.txt
+   ```
+
+2. **Run the script:**
+
+   ```bash
+   python3 ./scripts/validate-collections-yaml
+   ```
