 ## Basic requirements
 
 - Perl 5.42.0
 - Carton (handles perl deps)
 - Redis
 
-## Roadmap
-
-- [x] create installation script
-- [x] connect to redis + setter and getter operations
-- [ ] create dummy API endpoints
-- [ ] decide how to handle short url generation
-- [ ] avoid collisions in short urls
-- [ ] redirect to the original url
-- [ ] validate URLs and handle errors
-- [ ] create a simple and clean UI
-- [ ] manage/delete short urls
-- [ ] create systemd service
-- [ ] create `Dockerfile`
-- [ ] create `docker-compose.yml`
-- [ ] add unit tests along the way
