 # urupam
 
-Yet another url shortener
+`urupam` is a lightweight URL shortener built with Perl and Mojolicious, and backed by Redis.
+
+## 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
+
+## How to run
+
+To run the application in development, you'll first need a Redis server. The easiest way is to start a local Redis instance using Docker:
+
+```sh
+docker run --name mojo-redis -p 6379:6379 -d redis
+```
+
+Install Perl dependencies with [Carton](https://github.com/perl-carton/carton):
+
+```sh
+carton install
+```
+
+Start the application with `morbo`:
+
+```sh
+carton exec morbo bin/urupam
+```
+
+Open [http://127.0.0.1:3000](http://127.0.0.1:3000) in your browser.
+
+## Installation
+
+Run the installation script:
+
+```sh
+scripts/install.sh
+```
+
+Enable and start the systemd service:
+
+```sh
+sudo systemctl enable --now urupam
+```
+
+### Using docker
+
+Build the image and use the `docker-compose` file:
+
+```sh
+cd docker
+docker build -t urupam .
+docker compose up -d
+```
