+## Create a new blog post
+
+1. Create a new markdown file in the `posts` directory. For example, if you want to create a new blog post named `my-first-blog-post`, create a new file named `my-first-blog-post.md`.
+2. Add the frontmatter to the markdown file. The frontmatter is the metadata of your blog post. It contains the title, description, tags (SEO keywords), category, publish date, modified date, cover image of your blog post. Here is an example of the frontmatter.
+
+```mdx
+---
+title: Hello World
+description: 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor'
+tag:
+    - example
+    - demo
+category:
+    - test
+publishedDate: 2022-12-28T16:27:05.876Z
+lastModifiedDate: 2022-12-28T16:27:05.876Z
+cover: ''
+---
+```
+
+3. Add the content of your blog post to the markdown file. You can use React components in your markdown file. Click [here](#inject-markdown-components) if you want to learn how to inject React components in your blog. The following is an example of a markdown blog post that uses a React component.
+
+```md
+## Paragraph
+
+Lorem ipsum dolor sit amet, *consectetur* adipiscing elit, sed do eiusmod tempor **incididunt** ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea ***commodo*** consequat.
+
+<Note>
+    This is a sample note
+</Note>
+```
+
+4. If you want to locally look at the blog post in your browser, run the following command once in your terminal.
+
+```sh
+npm run generate-data
+```
+
+5. Now navigate to [`http://localhost:3000/blog/my-first-blog-post`](http://localhost:3000/blog/my-first-blog-post) to see your blog post.
+6. Once you are done, push the markdown file to your GitHub repository. Your blog post will be automatically deployed to your blog site.
+
+>You only need to run the command in step #4 once. You don't have to run it again after updating the file.
+
+## Create categories
+
+***Add a new category***
+
+To add a new category, go to the `data/categories.json` file and create an object with your category. For example, if you want to add a `life` category, add an object with a single `name` key inside they JSON array.
+
+```json
+[
+	{
+		"name": "life"
+	}
+]
+```
+
+***Use category in your blog file***
+
+To use this newly created `life` category in your blog file, just add it as a value to the category in your markdown file frontmatter. For example, if you want to add a `life` category to your blog post, here is how you can do it.
+
+```mdx
+---
+title: 'My first blog post'
+description: 'This is my first blog post'
+category:
+    - life
+---
+```
+
+***Category page***
+
+- Your blog site has a category page. To access this page, navigate to [`http://localhost:3000/blog/category`](http://localhost:3000/blog/category) to see all the different blog categories you have.
+- To access a specific category page, navigate to [`http://localhost:3000/blog/category/guide`](http://localhost:3000/blog/category/guide) to see all the blog posts with the `guide` category.
