+Kosmorro is a program that calculates your astronomical ephemerides.
 
 ## Installation
 
-### Production environment
-
-If you want to give a try to Kosmorro, head to [its official download page](https://kosmorro.space/cli/download/) and follow the instructions that correspond to your operating system.
+Installing Kosmorro is documented on [the official website](https://kosmorro.space/cli/download/). Just select your operating system and follow the instructions!
 
 ### Development environment

-
-- Python ≥ 3.8
-- PIP3
-- [Poetry](https://python-poetry.org/)
+To contribute to Kosmorrolib, you will need [Poetry](https://python-poetry.org), a software to manage the project from development to publishing.
 
-Clone this repository and run `poetry install` to install all the dependencies.
-Then, run Kosmorro by invoking `poetry run kosmorro`.
+Clone this repository and run `poetry install` to install the dependencies.
+And that's all, your development environment is ready!

+To run Kosmorro, invoke `poetry run kosmorro`. For comfort, you may also want to invoke `poetry shell`, which will expose the `kosmorro` command directly.
 
 ## Using Kosmorro
 
 Using Kosmorro is as simple as invoking `kosmorro` in your terminal!
 
 By default, it will give you the current Moon phase and, if any, the events that will occur today.
-To get the rise, culmination and set of the objects of the Solar system, you will need to give it your position on Earth: get your current coordinates (with [OpenStreetMap](https://www.openstreetmap.org) for instance), and give them to Kosmorro by invoking it with the following parameters: `--latitude=X --longitude=Y` (replace `X` by the latitude and `Y` by the longitude).
-
-Kosmorro has a lot of available options. To get a list of them, run `kosmorro --help`, or read its manual with `man kosmorro`.
-
-Note: the first time it runs, Kosmorro will download some important files needed to make the computations. They are stored in a cache folder named `.kosmorro-cache` located in your home directory (`/home/<username>` on Linux, `/Users/<username>` on macOS).
-
-### Exporting to PDF
 
-Kosmorro can export the computation results to PDF files, but this feature requires first that you install some additional dependencies.
-You can find documentation about this on [Kosmorro's website](https://kosmorro.space/cli/generate-pdf/).
+Kosmorro has a lot of available options to get exactly what you want, including the possibility to get planets rise and set. To get a list of them, run `kosmorro --help`, or read its manual with `man kosmorro`. You can also find usage examples in [the `tldr` manual](https://tldr.sh) with [`tldr kosmorro`](https://tldr.inbrowser.app/pages/common/kosmorro).
