+# Slow Tests Using Google Cloud Storage
+
+[Google Cloud Storage Browser](https://console.cloud.google.com/storage/browser/stwo-cairo-testing-artifacts?project=starkware-thirdparties)
+
+## How to Test
+
+1. **Download Tests Files**  
+   ```bash
+   ./scripts/fetch_large_files.sh
+   ```
+
+2. **Execute Tests**  
+   ```bash
+   cargo test test_read_from_large_files --features "slow-tests"
+   cargo test test_read_from_small_file --features "slow-tests"
+   ```
+
+## Adding a New "Slow-Test"
+
+1. **Create a Directory**  
+   Create a new directory at the Google Cloud Storage URL above and add the required files.
+
+2. **Mark the Test**  
+   Mark the new test with `#[cfg(feature = "slow-tests")]`.
+
+3. **Run Tests Locally**  
+    Run the test locally using:
+    ```bash
+    cargo test "<test_name>" --features "slow-tests"
