+# 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>
+```
+
+3. Step 2 should have generated an ssl_roots.h file right next to the pem file.
+
+4. Overwrite rtc_base/ssl_roots.h with the newly generated one.

+"""This is a tool to transform a crt file into a C/C++ header.
+
+Usage:
+python3 generate_sslroots.py certfile.pem [--verbose | -v] [--full_cert | -f]
+
+Arguments:
+  -v  Print output while running.
+  -f  Add public key and certificate name.  Default is to skip and reduce
+      generated file size.
+
+The supported cert files are:
+  - Google: https://pki.goog/roots.pem
