+# Lunatech COVID Assessment Instructions
+
+We’d like to invite you to do a code assessment as discussed during your
+interview. Please read these instructions carefully to ensure that you implement
+everything as expected. *Be sure to do your work on a separate branch and when
+you are ready for your code to be reviewed, open a pull request to the main
+branch*. This is important as it will signify that you've completed the
+assessment. After completing the assessment, developers from Lunatech will
+review your code and you'll be given the chance to "hand off" the application to
+them. You'll give a demo of your app, explain your technical choices, and
+discuss the application with them.
+
+The code assessment is not a puzzle; it's not meant to be tricky or confusing.
+If you have any questions do not hesitate to contact us, we'll be glad to answer
+them.
+
+## Guidelines
+
+  - Approach this assessment if as you were developing a real world project. We
+    want to see how you conduct your engineering practice (project structure,
+    code quality, readability, documentation and so on). GitHub Actions are
+    enabled for this repo, so feel free to use them.
+  - The one week limit is to be able to give rapid feedback, you can have more
+    time, just send us an email. It’s OK if you haven’t completed all the
+    requirements, the exercise is meant to start a discussion. Remember:
+    Quality over Quantity.
+  - When you're complete, make sure all of your code is pushed up to this repo
+    and let us know.
+  - You're free to use whatever tech stack you're comfortable with, just make
+    sure the stack makes sense given the assignment
+
+## The Details
+The goal of this assessment is to produce a web application written in Java or
+Scala, using data available in this repository. This application covers the
+following requirements:
+
+### Query:
+
+For this endpoint, given a country name, and date (eg. 14-06-2020), get the daily
+infections and deaths up until, and including, the specified date. For bonus points,
+make the test partial/fuzzy (e.g.  entering 'Zimb' will result in 'Zimbabwe').
+
+### Reports:
+
+This endpoint will return to the user the following reports:
+  - 10 countries with the highest vaccinations (with count), and countries
+    with lowest number of vaccinations.
+  - 10 countries with the highest infections per 100k inhabitants (with count)
+  - Bonus: If we consider all populations wants to become fully vaccinated (there is
+    no such thing as an Anti-Vaxxer), print countries that haven't vaccinated their
+    whole population with at least one shot or jab.
+
+## Setup
+
+To speed up the assessment development, we have provided a `docker-compose` file that
+will run a [PostgreSQL](https://www.postgresql.org/) instance with all the data loaded,
+which you can start with the following command: `docker-compose up`. You can connect to
+this instance from your application with the following values:
+
+```
+JDBC URL = jdbc:postgresql://localhost:5432/lunatech_covid
+Username = postgres
+Password = postgres
+```
+
+The schema is defined within the file `schema.sql` in the `database-init`
+folder. For whatever reason if you want to change anything in the
+`docker-compose` or re-use it in your own `docker-compose`, feel free. It's
+provided for your convenience.
