+## 7. How to integrate _pydoclint_ with different editors or IDEs
+
+### 7.1. Integrate _pydoclint_ with Neovim using null-ls
+
+If you use [Neovim](https://neovim.io/), you can integrate _pydoclint_ with
+your editor using the [null-ls](https://github.com/nvimtools/none-ls.nvim)
+plugin. null-ls allows you to use linters and formatters in Neovim in a simple
+and efficient way. First, make sure you have installed null-ls using your
+preferred package manager. Next, add the following configuration to your Neovim
+config file to register _pydoclint_ as a diagnostic source:
+
+```lua
+local null_ls = require("null-ls")
+
+null_ls.setup({
+    sources = {
+        null_ls.builtins.diagnostics.pydoclint,
+    },
+})
+```
+
+This will enable _pydoclint_ to provide diagnostic messages for your Python
+code directly in Neovim. You can further customize the behavior of _pydoclint_
+by passing additional options:
+
+```lua
+local null_ls = require("null-ls")
+
+null_ls.setup({
+    sources = {
+        null_ls.builtins.diagnostics.pydoclint.with({
+            extra_args = {"--style=google", "--check-return-types=False"},
+        }),
+    },
+})
+```
+
+Adjust the extra*args based on your preferred \_pydoclint* configuration. With
+this setup, you can now enjoy the benefits of _pydoclint_'s fast and
+comprehensive docstring linting directly within your Neovim editing
+environment.
