+# Hy {#sec-language-hy}
+
+## Installation {#ssec-hy-installation}
+
+### Installation without packages {#installation-without-packages}
+
+You can install `hy` via nix-env or by adding it to `configuration.nix` by reffering to it as a `hy` attribute. This kind of installation adds `hy` to your environment and it succesfully works with `python3`.
+
+::: {.caution}
+Packages that are installed with your python derivation, are not accesible by `hy` this way.
+:::
+
+### Installation with packages {#installation-with-packages}
+
+Creating `hy` derivation with custom `python` packages is really simple and similar to the way that python does it. Attribute `hy` provides function `withPackages` that creates custom `hy` derivation with specified packages.
+
+For example if you want to create shell with `matplotlib` and `numpy`, you can do it like so:
+
+```ShellSession
+$ nix-shell -p "hy.withPackages (ps: with ps; [ numpy matplotlib ])"
+```
+
+Or if you want to extend your `configuration.nix`:
+```nix
+{ # ...
+
+  environment.systemPackages = with pkgs; [
+    (hy.withPackages (py-packages: with py-packages; [ numpy matplotlib ]))
+  ];
+}
+```
