+## Installation
+
+(Note: These instructions need to be rewritten for use with the new service
+ locator and utility modules I've made recently.)
+
+1. From application root: `git submodule add https://github.com/lazuscripts/users users`
+
+2. Inside your application: `@include "users/users"`
+
+3. In migrations, do the following:
+   ```moonscript
+   import create_table, types from require "lapis.db.schema"
+   create_table "users", {
+       {"id", types.serial primary_key: true}
+       {"name", types.varchar unique: true}
+       {"digest", types.text}
+       {"admin", types.boolean default: false}
+   }
+   ```
+
+4. `bcrypt` Lua Rock must be installed!
+
+5. If `@session.redirect` is defined when going to the login route, a user will be
+   redirected there after logging in.
+
+Note: Assumes you have a route named "index" to redirect to when things go
+wrong.
+
+**WARNING**: Now expects you to display informational messages stored in
+`@session.info`.
+
+## Config
+
+`digest_rounds 9` must be set. Use a higher or lower number depending on how
+long it takes to calculate a digest or how paranoid you want to be. See this bit
+about tuning: https://github.com/mikejsavage/lua-bcrypt#tuning
+
+## Access
+
+To get the Users model for use outside of this sub-application:<br>
+`Users = require "users.models.Users"`
+
+Named routes:
+
+- user_new
+- user_me
+- user_admin
+- user_edit
+- user_login
+- user_logout
+- user_list
