===What is Instiki?

Admitted, it's YetAnotherWikiClone[http://c2.com/cgi/wiki?WikiWikiClones], but with a strong focus
on simplicity of installation and running:

Step 1. Download
Step 2. Run "instiki"

If you are on Windows:
"Step 3. Chuckle... "There's no step three!" (TM)"

You're now running a perfectly suitable wiki on port 2500 
that'll present you with one-step setup, followed by a textarea for the home page
on http://localhost:2500

Instiki lowers the barriers of interest for when you might consider
using a wiki. It's so simple to get running that you'll find yourself
using it for anything -- taking notes, brainstorming, organizing a 
gathering.

Having said all that, if you are not on Windows, in this version of Instiki it is a somewhat different story.
Since the author has no Linux or Mac at hand, and Instiki is moving to a SQL-based backend, this is what it takes 
to install (until somebody sends a patch to properly package Instiki for all those other platforms):

3. Kill "instiki"
4. Install SQLite 3 database engine from http://www.sqlite.org/
5. Install SQLite 3 driver for Ruby from http://sqlite-ruby.rubyforge.org/
6. Install Rake from http://rake.rubyforge.org/
7. Execute rm -f db/*.db
8. Execute 'rake environment RAILS_ENV=production migrate'
9. Make an embarrassed sigh (as I do while writing this)
10. Run 'instiki' again
11. Pat yourself on the shoulder for being such a talented geek
12. At least, there is no step twelve! (TM)

===Features:
* Regular expression search: Find deep stuff really fast
* Revisions: Follow the changes on every page from birth. Rollback to an earlier rev
* Export to HTML or markup in a zip: Take the entire wiki with you home or for reference
* RSS feeds to track recently revised pages
* Multiple webs: Create separate wikis with their own namespace
* Password-protected webs: Keep it private
* Authors: Each revision is associated with an author, so you can see who changed what
* Reference tracker: Which other pages are pointing to the current?
* Speed: Using Madelein[http://madeleine.sourceforge.net] for persistence (all pages are in memory)
* Three markup choices: Textile[http://www.textism.com/tools/textile] 
  (default / RedCloth[http://www.whytheluckystiff.net/ruby/redcloth]), 
  Markdown (BlueCloth[http://bluecloth.rubyforge.org]), and RDoc[http://rdoc.sourceforge.net/doc]
* Embedded webserver: Through WEBrick[http://www.webrick.org]
* Internationalization: Wiki words in any latin, greek, cyrillian, or armenian characters
* Color diffs: Track changes through revisions
* Definitely can run on SQLite and MySQL
* May be able to run on Postgres, Oracle, DB2 and SqlServer. If you try this, and it works 
  (or, it doesn't, but you make it work) please write about it on Instiki.org.

===Command-line options:
* Run "ruby instiki --help"

===History:
 * See CHANGELOG

===Migrating Instiki 0.10.2 storage to Instiki 0.11.0 database
1. Install Instiki 0.11 and check that it works (you should be able to create a web, edit and save a HomePage)
2. Execute 
      ruby script\import_storage \
          -t /full/path/to/instiki0.10/storage \
          -i /full/path/to/instiki0.10/installation \
          -d sqlite (or mysql, or postgres, depending on what you use) \
          -o instiki_import.sql
   for example (Windows):
   ruby script\import_storage -t c:\instiki-0.10.2\storage\2500 -i c:\instiki-0.10.2 -d sqlite -o instiki_import.sql
3. This will produce instiki_import.sql file in the current working directory. 
   Open it in a text editor and inspect carefully.
4. Connect to your production database (e.g., 'sqlite3 db\prod.db'), 
   and have it execute instiki_import.sql (e.g., '.read instiki_import.sql')
5. Execute ruby script\reset_references 
   (this script parses all pages for crosslinks between them, so it may take a few minutes)
6. Restart Instiki
7. Go over some pages, especially those with a lot of complex markup, and see if anything is broken.

The most common migration problem is this: if you open All Pages and see a lot of orphaned pages, 
you forgot to run ruby script\reset_references after importing the data.

===Upgrading from Instiki-AR Beta 1
In Beta 2, we switch to ActiveRecord:Migrations. Therefore:
1. Back up your production database.
2. Open command-line session to your database and execute: 
  create table schema_info (version integer(11)); 
  insert into schema_info (version) values (1);
3. Go back to the shell, change directory to the new Instiki and execute "rake migrate".

Step 2 creates a table that tells to ActiveRecord:Migrations that the current version 
of this database is 1 (corresponding to Beta 1), and step 3 makes it up-to-date with
the current version of Instiki.
