+# Simple SQL queries practise.
+
+In this assignment, you'll be writing a bunch of SQL queries to interact with your postgres database.
+
+## Pre-requisites
+Before you start, please grab a Postgres URL from either of the following - 
+ - https://neon.tech/
+ - https://aiven.io/
+
+and put it in config.ts
+
+## Assignment
+You are supposed to write the `database` part of an full stack app. 
+Specifically, you need to fill the functions in 
+ - src/db/user.ts
+ - src/db/todo.ts
+
+## Testing
+Run `npm run test` to run all the tests
+
+## Call out
+The schema of the tables looks like this - 
+```
+    CREATE TABLE IF NOT EXISTS users (
+        id SERIAL PRIMARY KEY,
+        username VARCHAR(255) UNIQUE NOT NULL,
+        password VARCHAR(255) NOT NULL,
+        name VARCHAR(255) NOT NULL
+    );
+    CREATE TABLE IF NOT EXISTS todos (
+        id SERIAL PRIMARY KEY,
+        user_id INTEGER NOT NULL REFERENCES users(id),
+        title VARCHAR(255) NOT NULL,
+        description TEXT,
+        done BOOLEAN DEFAULT false
+    );
+```
