Go to [database.new](https://database.new) and create a new Supabase project.
When your project is up and running, go to the [Table Editor](https://supabase.com/dashboard/project/_/editor), create a new table and insert some data.
Alternatively, you can run the following snippet in your project's [SQL Editor](https://supabase.com/dashboard/project/_/sql/new). This will create a `countries` table with some sample data.
```sql SQL_EDITOR
-- Create the table
create table countries (
id bigint primary key generated always as identity,
name text not null
);
-- Insert some sample data into the table
insert into countries (name)
values
('Canada'),
('United States'),
('Mexico');
alter table countries enable row level security;
```
Make the data in your table publicly readable by adding an RLS policy:
```sql SQL_EDITOR
create policy "public can read countries"
on public.countries
for select to anon
using (true);
```
