+Currently there is now way to cleanly package Bower on Nix.
+So we have to manually package cryptpad.
+
+To update, you have to:
+
+```bash
+nix-shell
+cd cryptpad
+git pull
+git checkout <tag>
+bower update
+npm install
+cd ..
+nix-build
+nix-build docker.nix

+/*  DISCLAIMER:
+
+    There are two recommended methods of running a CryptPad instance:
+
+    1. Using a standalone nodejs server without HTTPS (suitable for local development)
+    2. Using NGINX to serve static assets and to handle HTTPS for API server's websocket traffic
+
+    We do not officially recommend or support Apache, Docker, Kubernetes, Traefik, or any other configuration.
+    Support requests for such setups should be directed to their authors.
+
+    If you're having difficulty difficulty configuring your instance
+    we suggest that you join the project's IRC/Matrix channel.
+
+    If you don't have any difficulty configuring your instance and you'd like to
+    support us for the work that went into making it pain-free we are quite happy
+    to accept donations via our opencollective page: https://opencollective.com/cryptpad
+

+/*  CryptPad is designed to serve its content over two domains.
+ *  Account passwords and cryptographic content is handled on the 'main' domain,
+ *  while the user interface is loaded on a 'sandbox' domain
+ *  which can only access information which the main domain willingly shares.
+ *
+ *  In the event of an XSS vulnerability in the UI (that's bad)
+ *  this system prevents attackers from gaining access to your account (that's good).
+ *
+ *  Most problems with new instances are related to this system blocking access
+ *  because of incorrectly configured sandboxes. If you only see a white screen
+ *  when you try to load CryptPad, this is probably the cause.
+ *
+ *  PLEASE READ THE FOLLOWING COMMENTS CAREFULLY.

+ *
+ *  This is not appropriate in a production environment where invasive networks
+ *  may filter traffic going over abnormal ports.

+ *  with a different domain (a subdomain is sufficient).
+ *  It will be used to load the UI in our 'sandbox' system.

+ *  in the example nginx file.
