+Sorry, these instructions are incomplete. Currently they only document the `systemctl edit` and `setcap` commands that are necessary to allow snowflake-server to bind to ports 80 and 443.
+
+Override the `NoNewPrivileges` setting to enable snowflake-server to bind to low-numbered ports. (See tpo/core/tor#18356 for background.)
+
+```
+root# systemctl edit tor@.service
+        [Service]
+        NoNewPrivileges=no
+root# systemctl edit tor@default.service
+        [Service]
+        NoNewPrivileges=no
+```
+
+Install snowflake-server. Run a `setcap` command to enable the program to bind to low-numbered ports.
+
+```
+root# install --owner root snowflake-server /usr/local/bin/snowflake-server
+root# setcap 'cap_net_bind_service=+ep' /usr/local/bin/snowflake-server
+root# service tor restart
+```
