Bibi supports 3 ways to read/publish EPUB books:

• Read in browsers on your offline machine.
• Publish on the web to have your books read by someone.
• Use as an online EPUB viewer for your or visitors' local EPUBs.

In all cases,

1. Download Bibi from GitHub release page or Bibi website.
2. And unzip it at first.

The folder structure and default public URL has changed in Bibi v1.0.0. But don't worry. You still can use not only the new style URL but also the same old style URL as before.

If you already published books on the web with BiB/i which version is older than v1.0.0, and want to update Bibi to v1.0.0 or newer, but do not want to change the public URLs of the books,

• Please download Bibi-vX.Y.Z_with_BackCompatKit.zip, and follow the document in it.

1. Open bibi/index.html in your browser, and
2. Drag an EPUB book and drop it into the window.
3. That's all!

Demo.

You can publish both unzipped folder and zipped EPUB archive.

Using unzipped folder is recommended for the book which is heavy or contains many files. Using zipped EPUB file is recommended for the book which is light and contains less files.

In both ways, at first, upload bibi and 'bibi-bookshelf' folders to the same directory on your web server. bibi contains all programs of Bibi, and 'bibi-bookshelf' is for the storage of the books you upload. You can use different directory for the bookshelf instead of 'bibi-bookshelf' by editing "bookshelf" option in 'bibi/presets/default.js'.

1. Upload bibi and 'bibi-bookshelf' folders to the same directory on your web server.
2. Unzip an EPUB book,
   1. Change the file extension from .epub to .zip (BOOKNAME.epub -> BOOKNAME.zip), and
   2. Unzip the file with some tool.
3. Upload the unzipped folder BOOKNAME into bibi-bookshelf directory, and
4. Access to https://your.web.site/somewhere/bibi/?book=BOOKNAME by your browser. (note that it has no extension)
5. Or embed code below into your blog entry or other webpages, and visit the entry.

<a href="https://your.web.site/somewhere/bibi/?book=BOOKNAME" data-bibi="embed" data-bibi-style="[[ CSS for embeded Bibi frame, as you like ]]">[[ Title of the Book ]]</a><script src="https://your.web.site/somewhere/bibi/and/jo.js"></script>

1. Upload bibi and 'bibi-bookshelf' folders to the same directory on your web server.
2. Upload your EPUB book (ex. BOOKNAME.epub) to bibi-bookshelf directory, and
3. Access to https://your.web.site/somewhere/bibi/?book=BOOKNAME.epub by your browser.
4. Or embed code below into your blog entry or other webpages, and visit the entry.

<a href="https://your.web.site/somewhere/bibi/?book=BOOKNAME.epub" data-bibi="embed" data-bibi-style="[[ CSS for embeded Bibi frame, as you like ]]">[[ Title of the Book ]]</a><script src="https://your.web.site/somewhere/bibi/and/jo.js"></script>

1. Upload bibi folder on your web server.
2. Navigate visitors to https://your.web.site/somewhere/bibi/.
3. Visitors can read one's local EPUBs by draging and dropping EPUBs into the window.

If you want to terminate this feature, set "no" to "accept-files" in bibi/presets/default.js.
