+# Installation Guide {anchor=false}
+
+Heavily WIP and incomplete.
+
+## Pre-requisites
+
+- A computer that meets the [system requirements](#system-requirements)
+- A big enough storage drive for the install media that you are fine with erasing
+- **(Optional, but recommended)**: read through the [frequently asked questions](/docs/getting-started/frequently-asked-questions)
+
+## System Requirements
+
+> [!INFO]
+> These should be treated as a rough guideline. UEFI and 64-bit are the only hard requirements (Apollo won't boot without these), but we recommend the following for the best experience:
+
+- **UEFI** firmware (any computer from within the last decade should have this)
+- **SSD** storage with at least 40GB free for Apollo
+- An **x86_64** capable processor with at least 2 cores running at 2GHz or better
+- At least **4GB** of RAM, ideally more, especially for running containerised workloads
+- Modern AMD/Intel graphics, or for Nvidia anything Turing (GTX/16xx or RTX 20xx) or newer using the `apollo-nvidia` image. 
+    - Older Nvidia GPUs may still work with the regular image (`apollo`), however these only ship the open source nouveau drivers which typically have worse performance compared to the proprietary drivers.
