Sure, I can post it here. It sounds really complicated, but it's not that bad once you do it a few times.
Note: This is how *I* do formatting, just because it's easier for me to go back and forth with the files if there is a mistake. It's basic, but it gets the job done.
1. Clean up and take all the metadata out of the final Word document.
-paragraphs are correctly automatically indented and not tabbed
-no extra spaces (you can do a Find and Replace All for this)
-no unnecessary spaces between paragraphs
-make sure alignment is justified
-take out page breaks (you can do this by hitting the pilcrow/paragraph icon on the home tab in Word and they should show up as dotted lines)
-make sure there is no track changes or comments in document
-remove any page numbers, or any other header/footer info
2. Put all chapter titles in headings. Make sure chapter titles are in a larger font and bolded, and put about 2-3 lines between text.
-Just highlight the chapter title and click on headings at the right of the home tab. This is adding metadata, but you're doing it so you can force a table of contents to be made in Calibre.
3. Save the file in SAVE AS and choose web page.
4. Open up Calibre. Hit Add Books on top left, choose "add books from single directory." Import file. Once it's downloaded, it'll show up in a numbered list on the main box.
5. Making sure the file is highlighted, click on Convert Books and choose "convert individually."
6. In the screen that pop ups, pay careful attention. The button at the top left is the input format, and the button on the top right is output format. You can switch output format in between epub or mobi. I usually format epub first, then convert the epub into the mobi second step.
7. At the right, add in title, author name, and series name (if applicable.) At the left, under the book picture, it says "change cover picture." There should be a small blue icon. Hit that and you can upload the file for your cover.
8. At the left, click on the paint can icon "Look and Feel." Check yes for "Remove spacing between paragraphs." Ignore everything else in there.
9. At the left, click on "Table of Contents." Check yes for "Force use of auto-generated Table of Contents."
-Go down the menu to Level 1 TOC (XPath expression.) Click on the weird wand icon at the right.
-Another window will pop up. On the first menu line "Match HTML tags with tag name," you'll get a drop down menu. Choose "h1" and hit okay.
10. At the bottom left, hit okay. Calibre will convert the file and it will show up in the main box with it's title. Double-click on it and you can look it over in the Calibre viewer, but for checking for errors and typos, it's best to save the file to disc and then transfer it to an ereader.
11. To do a mobi, do the Convert Book thing again, but make sure the input is the epub and the output file is mobi. You don't have to make any other changes, just hit okay.
