-## Scripts
-The following shell scripts are present in the `scripts/` directory.
-
-- `update-gh-pages`: This script can be used to update the `gh-pages` branch of this repo or a fork.
- This script is not meant to be used directly as it runs in the current working directory.
- If you run it on your primary local clone, it can **delete** the local changes. This script is made to be used in a github action
- or in a temporary directory via another script, such as `update-demo`.
-
-  Arguments:
-  1. Repo(to use as upstream) url in the form username/repo (default: publiclab/image-sequencer) NOTE: Github only
-  2. Branch to pull from eg: main or stable (default: stable)
-  3. CNAME URL (default: none)
-  4. Set the fourth argument to anything to bypass the warning. You will have to set this argument if you want to run this script in another script without needing
-  user interaction, such as in a github action.
-
-- `update-demo`: A safe, interactive script that can be used to update the `gh-pages` branch of any image-sequencer fork.
- This script is safe to use directly because it separately clones the repo in a temporary directory.
-
-  Arguments: None since it is a an *interactive* script, ie it asks the user for input.
