+# Generate rtc_base/ssl_roots.h
+
+This directory contains a script to generate the content of
+[rtc_base/ssl_roots.h][ssl-roots-header], to update the SSL roots shipped
+by WebRTC follow this instructions:
+
+1. Download roots.pem from [pki.goog][pki-goog] or [curl.se][mozilla-cacert]
+
+2. Launch the script:
+
+```
+$ vpython3 tools_webrtc/sslroots/generate_sslroots.py <the pem file>
+```
