 This guide helps you install ABACUS with basic features. **For DeePKS, DeePMD and Libxc support, or building with `make`, please refer to [the advanced installation guide](../advanced/install.md)** after going through this page. We recommend building ABACUS with `cmake` to avoid dependency issues. We recommend compiling ABACUS(and possibly its requirements) from the source code using the latest compiler for the best performace. You can also deploy ABACUS **without building** by [Docker](#container-deployment) or [conda](#install-by-conda). Please note that ABACUS only supports Linux; for Windows users, please consider using [WSL](https://learn.microsoft.com/en-us/windows/wsl/) or docker.
