 A simple telegram bot that describes current weather (currently for Otaniemi, Espoo) and predicts the "beautifulness" of the day using previously learnt data.
 
 ## Development
-Currently only works on x86 only because of Prisma binaries (tested on Linux)
 
 For development you need:
-- [pipenv](https://pipenv.pypa.io/en/latest/)
-- Python 3.11 is required in the Pipfile, highly recommended
+- [uv](https://docs.astral.sh/uv/)
+- Python 3.13
 - A free API key from [OpenWeatherMap](https://openweathermap.org/current)
-- A Postgres database (local/remote)
+- A libSQL database (local/remote)
 - A TG bot API key
 
-1. Install dependencies:
-
-       pipenv install --dev
-2. setup environment variables inside `.env`
-3. generate Prisma binaries:
-
-       pipenv run generate
-4. setup database:
-
-       pipenv run db push
-5. to start dev environment run:
-
-       pipenv run dev
 
-## Production
+## Production (Docker deployment)
 
 For production you need (or is recommended at least):
 - [Docker](https://docs.docker.com/get-docker/)
