+# netstream
+ Parallel asynchronous network requests via tor proxy
+
+ ## Usage
+ Simply feed all page urls to the Netstream module[^1] and it will start a parallel asynchronous process to load the required resources
+
+ ## Examples
+ ```python
+  from netstream import Netstream
+
+  urls = [fr'https://ya.ru', fr'http://jsonip.com']
+  ns = Netstream()
+  data = ns.run(targets=urls)
+  complete = f'{100*ns.received/ns.total:.0f}' if ns.total else 0
+  print(f'result {complete}% (errors {ns.total-ns.received}) ')
+  print(f'{data}')
+   ```
+  ## Remarks
+  Netstream used Tor Browser resources.
+  [^1]: Tor browser must be running and active at this time
