+---
+
+The `.mintignore` file allows you to exclude specific files and directories from being processed and published to your documentation site.
+
+Use `.mintignore` to keep drafts, internal notes, and source files out of your public documentation while maintaining them in your repository.
+
+## Creating a .mintignore file
+
+Create a `.mintignore` file in the root of your docs directory. This file uses the same pattern syntax as `.gitignore`, making it familiar and easy to configure.
+
+```plaintext .mintignore
+# Exclude draft documents
+drafts/
+*.draft.mdx
+
+# Exclude internal documentation
+internal/
+
+# Exclude specific files
+private-notes.md
+```
+
+When Mintlify builds your documentation, it reads the `.mintignore` file and excludes any matching files or directories from processing. Excluded files:
+
+- Won't appear in your published documentation
+- Won't be indexed for search
+- Won't be accessible to visitors
+
+<Note>
+  Unlike [hidden pages](/organize/hidden-pages), files excluded by `.mintignore`
+  are completely removed from your site and cannot be accessed by URL.
+</Note>
+
+## Pattern syntax
+
+The `.mintignore` file follows `.gitignore` syntax. Here are common patterns:
+
+| Pattern            | Description                                    |
+| ------------------ | ---------------------------------------------- |
+| `drafts/`          | Excludes the entire `drafts` directory         |
+| `*.draft.mdx`      | Excludes all files ending in `.draft.mdx`      |
+| `private-notes.md` | Excludes a specific file                       |
+| `**/internal/**`   | Excludes any `internal` directory at any level |
+| `!important.mdx`   | Negates a previous pattern (includes the file) |
