Chapter 1: Posts
1.1 Normal post
To add a new post on your WordPress blog login to your admin area.
On the left side choose Posts 
 and choose "Add new"
Enter a title for the post and text.
Once you're done hit Publish
1.2 Titles/Headings
On a post you can add several subtitles and several levels of subtitles. To do this use the preset heading styles. This allows you to have them looking the same throughout your blog. To apply a heading style to a title you need to add the title between heading tags
<h1>Your title</h1> for level 1
<h2>Your title</h2> for level 2
<h3>Your title</h3> for level 3
and up until level 6.
The looking of these styles are different for each theme so you will have to try out what they look like.
1.3 Categories and Tags
To organize your posts on WordPress you can divide them into Categories (or groups) and Sub-Categories. To do that have a look at this fiels
To add a new Category hit "Add New Category" and enter the name of it and hit add
You will now see that the Category appears on the list
To add a Sub-Category choose again "Add New Category" and under Parent category choose the main category of the new one. In the example here Rock will be a sub-category of Music.
Hit add and you will see the sub-category appearing in the list
Another way to organize the posts is by using Tags. Tags are short keywords which tell the visitors and search engines what the post is about. Separate keywords with commas such as “Thea Beatles, Yellow Submarine, Youth” and hit "Add"
1.4 Sticky, Password protected, Private
You can make a post to be a Sticky. Sticky means that this post will stay at the top of the front page. Even if you add more posts afterwards the post will still be at the top and the newer posts will follow after it. This is used for special or important announcements.
To do this go to the section called "Publish", under "Visibility" hit "Edit" and choose "Stick this post to the front of the page".
You can also password protect it or make it private so only you see it.
1.5 Publish with time delay
If you want to write multiple posts at a time and have them being published one after the other maybe also while you're on vacation and don't have access to a computer then you can set a publishing time delay.
Per default posts are published immediately but if you hit "Edit" you can set a date and time for the post to be published. Once you entered the date and time hit "Ok" and "Publish".
1.6 Edit/Delete a post
Once you're logged in to your blog you will find an "Edit" button on each of your posts in case you want to edit it. Otherwise go to to your admin area and hit "Posts", "Edit" and you will see a list of your posts. When you select the post of interest you will see some links appearing "Edit, Quick Edit, Delete, View".
Chapter 2: Pages
2.1 Pages
To add a page go to your site administration area hit page and Add new
Choose a title for it which will display in the menu and write the content. Again you can use headings for sub-titles as in posts.
2.2 Sub-Pages
In WordPress you can add Sub-Pages to the Main-Pages. To achieve this go to the page's Attributes section and choose a Parent page, main page for the new one. In the example I've set Webmaster as the parent page.
This helps you keeping your website organized for what concerns the URL and the admin area.
2.3 Pages’ order
Under Appearance, Menus you can build your own menu.
Under Pages choose the pages you want to have displaying in the menu then hit Add to Menu
Under Custom Links you can enter a name and a URL to link pages from other websites or blog installations right in the menu.
Once you add the pages and custom links you will see them appearing on your right hand side. Just drag&drop them into the order you want them to display in the menu and don't forget to enter a name for the menu. Then hit Save Menu.
Under Theme Locations now select your custom menu and hit Save.
