+## Scripts
+
+### enable_jp_locale
+
+Enables the japanese locale on the steamdeck. Useful for learners of japanese that have to interact with e.g. zip archives with japanese characters in file names
+```bash
+LANG=ja_JP 7zz x <zip-archive>
+```
+
+### install_lein
+
+Installs [Leiningen](https://leiningen.org/) for clojure development. I suggest combining this with installing java via [SDKMAN](https://sdkman.io/).
+
+### install_neovim
+
+Installs [neovim](https://neovim.io/) in `${HOME}/bin/nvim`. By default the nightly version is chosen. You may want to install this via `distrobox` in a dedicated development container.
+
+### install_podman-compose
+
+Installs `aardvark-dns` and `podman-compose` for support of docker-compose files.
+
+### install_xclip
+
+Installs xclip, which is useful for copying and pasting in and out of [neovim](https://neovim.io/), [mpv](https://mpv.io/) with stuff like [mpvacious](https://github.com/Ajatt-Tools/mpvacious) etc.
