+# CGI Example Project
+
+The goal of this project is to give a working example of a basic Gemini CGI application. User identities are driven by TLS Client Certificates. This project will serve as a reference for CGI authors and be explained in detail in an instructional video.
+
+## Features
+
+* (DONE) New TLS certificates automatically create a new user account
+* (DONE) Users can set data on their own account (a name field for example)
+* (DONE) Users can add additional certificates to the same account by using a special code
+
+## Setup
+
+Create database with:
+
+``` sqlite command to create database
+sqlite3 db/cgi-example.sqlite3 < create_schema.sql
+```
+
+Then give write permission to the both the database and the containing directory (`db`) to the user that your Gemini server runs as. It is important that the containing folder write permissions are in place or you will see `50` errors returned when trying to write to the database.
