+Releasing pgcli
+---------------
+
+We have a script called `release.py` to automate the process.
+
+The script can be run with `-c` to confirm or skip steps. There's also a `--dry-run` option that only prints out the steps.
+
+```
+> python release.py --help
+Usage: release.py [options]
+
+Options:
+ -h, --help show this help message and exit
+ -c, --confirm-steps Confirm every step. If the step is not confirmed, it
+ will be skipped.
+ -d, --dry-run Print out, but not actually run any steps.
