+Install the plugin in Neovim (see [Nix instructions](#in-a-nix-flake-optional)) and run the plugin setup.
 ```lua

 3. Install the typstar python package (I recommend using [pipx](https://github.com/pypa/pipx) via `pipx install git+https://github.com/arne314/typstar`, you will need to have python build tools and clang installed) \[Note: this may take a while\]
 4. Make sure the `typstar-anki` command is available in your `PATH` or modify the `typstarAnkiCmd` option in the [config](#configuration)

+### In a Nix Flake (optional)
+You can add typstar to your `nix-flake` like so
+```nix
+# `flake.nix`
+inputs = {
+  # ... other inputs
+  typstar = {
+    url = "github:arne314/typstar";
+    flake = false;
+  };
+}
+```
+Now you can use `typstar` in any package-set
+```nix
+with pkgs; [
+  # ... other packges
+  (pkgs.vimUtils.buildVimPlugin {
+     name = "typstar";
+     src = inputs.typstar; 
+     buildInputs = [
+        vimPlugins.luasnip 
+        vimPlugins.nvim-treesitter-parsers.typst
+     ];
+  })
+]
+```
+
 ## Configuration
 Configuration options can be intuitively derived from the table [here](./lua/typstar/config.lua).

+### Custom snippets
+The [config](#configuration) allows you to
+- disable all snippets via `snippets.enable = false`
+- only include specific modules from the snippets folder via e.g. `snippets.modules = { 'letters' }`
+- exclude specific triggers via e.g. `snippets.exclude = { 'dx', 'ddx' }`
+
+For further customization you can make use of the provided wrappers from within your [LuaSnip](https://github.com/L3MON4D3/LuaSnip/) config.
+Let's say you prefer the short `=>` arrow over the long `==>` one and would like to change the `ip` trigger to `imp`.
+Your `typstar` config could look like
+```lua
+require('typstar').setup({
+    snippets = {
+        exclude = { 'ip' },
+    },
+})
+```
+while your LuaSnip `typst.lua` could look like this (`<` and `>` require escaping as `<>` [introduces a new node](https://github.com/L3MON4D3/LuaSnip/blob/master/DOC.md#fmt))
+```lua
+local tp = require('typstar.autosnippets')
+local snip = tp.snip
+local math = tp.in_math
+local markup = tp.in_markup
+
+return {
+    -- add a new snippet (the old one is excluded via the config)
+    snip('imp', '=>> ', {}, math),
+
+    -- override existing triggers by setting a high priority
+    snip('ib', '<<= ', {}, math, 2000),
+    snip('iff', '<<=>> ', {}, math, 2000),
+
+    -- setup markup snippets accordingly
+    snip('IMP', '$=>>$ ', {}, markup, 2000),
+    snip('IFF', '$<<=>>$ ', {}, markup, 2000),
