+## CHITTER CHALLENGE
 
 We are going to write a small Twitter clone that will allow the users to post messages to a public stream.
 
-## Set up
+## SETTING UP THE DATABASE
 
-To setup the database:
+1. Connect to `psql` (you may need to install postgresql first by running `brew install postgres`)
+2. Create the database using the psql command `CREATE DATABASE chitter`
+3. Connect to the database using the pqsl command `\c chitter`
+4. Run the query we have saved in the file **01_create_chitter_table.sql**
+5. Run the query we have saved in the file **02_create_author_table.sql**
+6. Run the query we have saved in the file **03_add_timestamp_to_peeps.sql**
+7. Populate your table by running the queries saved in the file **04_insert_data_to_peeps.sql** and **05_insert_data_to_author.sql**
 
-* Connect to psql
-* Create the database using the psql command `CREATE DATABASE chitter;`
-* Connect to the database using the psql command `\c chitter`;
-* Run the query we have saved in the file 01_create_chitter_table.sql
-* Populate your table with a row by running `INSERT INTO peeps (message) values ('This is a peep!');`
+To check you have everything set up ok, please take a look at the peeps table and the author inside the chitter database.
 
-To check you have everything set up ok, please take a look at the peeps table inside the chitter database. You should see one row in there.
