+This directory contains scripts used by ChromeDriver team to make public
+releases of ChromeDriver.
+
+The following steps are involved:
+
+* Go to the following URL to review bugs fixed in the release, replacing the
+  trailing 81 with actual ChromeDriver major version number:
+
+  https://crbug.com/chromedriver?can=1&sort=id&q=label:ChromeDriver-81
+
+* After reviewing the above page and making and necessary updates, click on the
+  "CSV" link near the lower-right corner to download the bug list to
+  ~/Download/chromedriver-issues.csv.
+
+* Run Python script `release_notes.py` to generate release notes. It requires
+  one command line argument, which is the full
+  [4-part version number](https://www.chromium.org/developers/version-numbers)
+  of the new release.
+  The script is hardcoded to read ~/Download/chromedriver-issues.csv,
+  and save the resulting file in notes.txt in the current directory.
+
+* Run shell script `release.sh` to copy ChromeDriver binaries and release notes
+  to the release web site. This script takes one argument, the full 4-part
+  version number of the new release.
+
+
+Notes:
+
+* If you encounter error that gsutil can't be found, install it with:
+
+    sudo apt-get install google-cloud-sdk
+
+* If you encounter permission errors from gsutil, run the following command and
+  login with an account that has permission to update gs://chromedriver.
+
+    gcloud auth login
+
+* If `LATEST_RELEASE` file needs updating, it can be done manually, e.g.,
+
+    gsutil cp gs://chromedriver/LATEST_RELEASE_81 gs://chromedriver/LATEST_RELEASE
