+[![CI](https://github.com/JaroslavTulach/AOC-2024-Enso/actions/workflows/enso.yml/badge.svg)](https://github.com/JaroslavTulach/AOC-2024-Enso/actions/workflows/enso.yml)
+
 Solving tasks for [AoC 2024](https://adventofcode.com/2024) in [Enso](http://enso.org).
+
+## Setup & Execution
+
+Enso can run on Linux, Windows, MacOSX. Download correct `enso-launcher` package
+for your operating system. Use version [2024.4.2](https://github.com/enso-org/enso/releases/tag/2024.4.2).
+The following steps are tested on Linux:
+```bash
+$ git checkout https://github.com/JaroslavTulach/AOC-2024-Enso.git
+$ cd AOC-2024-Enso
+```
+the two commands give you this repository with Enso projects in DecXY folders. Then install Enso:
+```bash
+$ wget https://github.com/enso-org/enso/releases/download/2024.4.2/enso-launcher-2024.4.2-linux-amd64.tar.gz
+$ tar fxvz enso-launcher-2024.4.2-linux-amd64.tar.gz
+$ ./enso/bin/ensoup install engine 2024.4.2
+$ ./enso/bin/ensoup list
+Enso 2024.4.2 -> GraalVM 24.0.0-java21.0.2
+```
+Now you can select an existing project and execute it. To execute for example `Dec03` invoke:
+```bash
+$ ./enso/bin/ensoup run Dec03
