 # Basic Usage
 
-## Installation
+## What you need
 
-- Recommended: Install the [Haskell Platform](https://www.haskell.org/platform/)
-- Includes everything you need to start with Haskell
-- Just installing the GHC alone is enough for this workshop
+- a **code editor**. I recommend VSCodium/Visual Studio Code with the Haskell extension (`haskell.haskell`)
+- **GHC**, the Haskell compiler, including **GHCi**, the interactive Haskell shell
+  - on Linux, install it using your package manager. The package is probably named `ghc` or similar. \
+    Alternatively, use ghcup: <https://www.haskell.org/ghcup/>
+  - on Windows, install using Chocolatey: <https://www.haskell.org/downloads/>.
+  - on macOS, install using ghcup: <https://www.haskell.org/ghcup/>
+- **Stack**, the Haskell project, package and build tool. It can also run a GHCi using `stack ghci` if you couldn't install GHC directly
+  - on Linux, install it using your package manager
+  - alternatively and for other OS's: <https://docs.haskellstack.org/en/stable/install_and_upgrade/>
+
+## What you need
+
+### Most important:
+
+You can start a somewhat current GHCi (version 8 or newer should be fine)
 
 ## GHCI

 Haskell can of course also be compiled into executable programs with `ghc`, but that comes later.
 
 For now we'll use only the GHCi. It's great for trying out stuff.

-## Stack

-Just so you know: for projects, you'd want to use Stack.
