-# Advent of Code 2019
-
-This project contains my implementations for Advent of Code 2019. The
-goal is to create reasonably fast C++ implementations in readable and
-ergonomic C++. At the end of the contest, I will probably do a write-
-up of some sorts. 
-
-
-## How to compile
-
-Install the dependencies:
-
-- [GTest](https://github.com/google/googletest) **Note:** this project
-  by default tries to dynamically link GTest, and the Ubuntu packages
-  only provide a statically linked archive. You may need to compile it
-  for yourself.
-
-```
-mkdir build && cd build
-cmake ..
-make
-```
-
-You can then use the generated executable `runner`.
-
-## Running tests
-
-Tests can be executed with `make test`. The `tests` folder contains a
-`samples` folder. This folder contains pairs of `XX-Y-something.in` and
-`XX-Y-something.out`, which will be taken as the expected input and
-output of the implementations. You can add your own samples to this mix.
