+# Custom keymaps {#ch-keymaps}
+
+Some plugin modules provide keymap options for your convenience. If a keymap is
+not provided by such module options, you may easily register your own custom
+keymaps via {option}`vim.keymaps`.
+
+```nix
+{
+  config.vim.keymaps = [
+    {
+      key = "<leader>m";
+      mode = "n";
+      silent = true;
+      action = ":make<CR>";
+    }
+    {

+## Custom LSP Servers {#ch-custom-lsp-servers}
+
+Neovim 0.11, in an effort to improve the out-of-the-box experience of Neovim,
+has introduced a new `vim.lsp` API that can be used to register custom LSP
+servers with ease. In **nvf**, this translates to the custom `vim.lsp` API that
+can be used to register servers that are not present in existing language
+modules.
+
+The {option}`vim.lsp.servers` submodule can be used to modify existing LSP
+definitions OR register your own custom LSPs respectively. For example, if you'd
+like to avoid having NVF pull the LSP packages you may modify the start command
+to use a string, which will cause the LSP API to discover LSP servers from
+{env}`PATH`. For example:
+
+```nix
+{lib, ...}: { 
+  vim.lsp.servers = {
+    # Get `basedpyright-langserver` from PATH, e.g., a dev shell.
+    basedpyright.cmd = lib.mkForce ["basedpyright-langserver" "--stdio"];
+
+    # Define a custom LSP entry using `vim.lsp.servers`:
+    ty = {
+      cmd = lib.mkDefault [(lib.getExe pkgs.ty) "server"];
+      filetypes = ["python"];
+      root_markers = [
+        ".git"
+        "pyproject.toml"
+        "setup.cfg"
+        "requirements.txt"
+        "Pipfile"
+        "pyrightconfig.json"
+      ];
+
+    # If your LSP accepts custom settings. See `:help lsp-config` for more details
+    # on available fields. This is a freeform field.
+    settings.ty = { /* ... */ };
+  };
+}
+```
