+# *W*rapped _d2_
+
+A wrapper over [d2] which allows to use \`layout\`, \`theme\`, \`pad\`
+attributes from d2 file. All arguments will be passed to the d2 cli, but these
+additional configs overwrite cli arguments with the same name.
+
+[d2]: https://github.com/terrastruct/d2
+
+# Install
+
+## Nix Flake
+
+This repo is also packaged via Nix flakes, the language server binary package is
+available through the default flake output `github:pleshevskiy/wd2` with the
+path `bin/wd2`.
+
+You can enable flakes support in your nix configuration, and then run nix
+profile install `github:pleshevskiy/wd2` to get `wd2` installed. You can also
+use this repository as a flake input and add its output to your own
+flake-managed systemwide or home configuration.
+
+## Other
+
+Copy `wd2` script to `/usr/local/bin` folder.
+
+# Usage
+
+Create a d2 file with additional configs at the top.
+
+```d2
+# layout: elk
+# theme: 101
+# pad: 5
+
+x -> y -> z
+```
+
+Then run the `wd2` script
+
+```sh
+wd2 -w path/to/your/file.d2
+```
