+The point of this project is to enable signing up for tilde.town via an ssh connection.
+
+It ought to work something like this:
+
+```bash
+
+ssh signup@tilde.town
+
+       <ascii art>
+
+       tilde.town
+
+
+a creature stands before you. what does it look like?
+
+  > a floating gray cube
+    a calico cat with softly glowing eyes
+    a squid
+    something else
+
+cube: you'd like to sign up for tilde.town, yes?
+
+ > yeah
+   nah
+   why should I?
+
+you say, "yeah"

+cube: by what name should i call you?
+
+  ~cowcow________

+cube: unfortunately, i already know someone by that name. what else can i call you?
+
+  ~shelf_________
+
+cube: excellent, hello ~shelf. have you been invited here by anyone i know?

+# New commands for signups
+
+## town-signup
+
+this binary is run by OpenSSH when a user anywhere in the world runs `ssh join@tilde.town`. It should:
+
+- collect information about an application from a user
+- allow them to edit their responses before submitting
+- write a yaml file of their responses to disk 
+
+## review-signups
+
+this binary is run by town admins in order to review, approve, notate, and reject applications. It should:
+
+- iterate over signups
+- allow fuzzy finding a particular signup
+- allow approval using create-user
+- allow rejection
+  - just move signup to archived rejected signup directory
+- allow notating an application, ie:
+  - lock the yaml file for writing
+  - add notes to the yaml file that can be seen by other admins
+- print info about historical signups
+
+## create-user
+
+this binary is called by `review-signups` to take a yaml application and create a user on disk. It should:
+
+- create the user idempotently
+  - `adduser`
+  - `usermod` to set group
+  - calling `add-key` for user
+- move the yaml file to an archive directory of approved signups
+
+## user-key
+
+this binary helps manage keys for users; basically automating the listing, adding, and removing of public keys for a user.
+
+- `user-key add <username> <keyfile`
+- `user-key list <username>`
+- `user-key remove <username>`
