+
+Install
+ How to install the Phorum HTML Purifier plugin
+
+0. PREREQUISITES
+----------------
+This Phorum module only works on PHP5 and with HTML Purifier 4.0.0
+or later.
+
+1. UNZIP
+--------
+Unzip phorum-htmlpurifier-x.y.z, producing an htmlpurifier folder.
+You've already done this step if you're reading this!
+
+2. MOVE
+-------
+Move the htmlpurifier folder to the mods/ folder of your Phorum
+installation, so the directory structure looks like:
+
+phorum/
+ mods/
+ htmlpurifier/
+ INSTALL - this install file
+ info.txt, ... - the module files
+ htmlpurifier/
+
+3. INSTALL HTML PURIFIER
+------------------------
+Download and unzip HTML Purifier <htmlpurifier.org>. Place the contents of
+the library/ folder in the htmlpurifier/htmlpurifier folder. Your directory
+structure will look like:
+
+phorum/
+ mods/
+ htmlpurifier/
+ htmlpurifier/
+ HTMLPurifier.auto.php
+ ... - other files
+ HTMLPurifier/
+
+Advanced users:
+ If you have HTML Purifier installed elsewhere on your server,
+ all you need is an HTMLPurifier.auto.php file in the library folder which
+ includes the HTMLPurifier.auto.php file in your install.
+
+4. MIGRATE
+----------
+If you're setting up a new Phorum installation, all you need to do is create
+a blank migrate.php file in the htmlpurifier module folder (NOT the library
+folder.
+
+If you have an old Phorum installation and was using BBCode,
+copy migrate.bbcode.php to migrate.php. If you were using a different input
+format, follow the instructions in migrate.bbcode.php to create your own custom
+migrate.php file.
+
+Your directory structure should now look like this:
+
+phorum/
+ mods/
+ htmlpurifier/
+ migrate.php
+
+5. ENABLE
+---------
+Navigate to your Phorum admin panel at http://example.com/phorum/admin.php,
+click on Global Settings > Modules, scroll to "HTML Purifier Phorum Mod" and
+turn it On.
+
+6. MIGRATE SIGNATURES
+---------------------
+If you're setting up a new Phorum installation, skip this step.
+
+If you allowed your users to make signatures, navigate to the module settings
+page of HTML Purifier (Global Settings > Modules > HTML Purifier Phorum Mod >
+Configure), type in "yes" in the "Confirm" box, and press "Migrate."
+
+ONLY DO THIS ONCE! BE SURE TO BACK UP YOUR DATABASE!
+
+7. CONFIGURE
+------------
+Configure using Edit settings. See that page for more information.

+
+HTML Purifier Phorum Mod - Filter your HTML the Standards-Compliant Way!
+
+This Phorum mod enables HTML posting on Phorum. Under normal circumstances,
+this would cause a huge security risk, but because we are running
+HTML through HTML Purifier, output is guaranteed to be XSS free and
+standards-compliant.
+
+This mod requires HTML input, and previous markup languages need to be
+converted accordingly. Thus, it is vital that you create a 'migrate.php'
+file that works with your installation. If you're using the built-in
+BBCode formatting, simply move migrate.bbcode.php to that place; for
+other markup languages, consult said file for instructions on how
+to adapt it to your needs.
+
+ -- NOTE -------------------------------------------------
+ You can also run this module in parallel with another
+ formatting module; this module attempts to place itself
+ at the end of the filtering chain. However, if any
+ previous modules produce insecure HTML (for instance,
+ a JavaScript email obfuscator) they will get cleaned.
+
+This module will not work if 'migrate.php' is not created, and an improperly
+made migration file may *CORRUPT* Phorum, so please take your time to
+do this correctly. It should go without saying to *BACKUP YOUR DATABASE*
+before attempting anything here. If no migration is necessary, you can
+simply create a blank migrate.php file. HTML Purifier is smart and will
+not re-migrate already processed messages. However, the original code
+is irretrievably lost (we may change this in the future.)
+
+This module will not automatically migrate user signatures, because this
+process may take a long time. After installing the HTML Purifier module and
+then configuring 'migrate.php', navigate to Settings and click 'Migrate
+Signatures' to migrate all user signatures to HTML.
+
+All of HTML Purifier's usual functions are configurable via the mod settings
+page. If you require custom configuration, create config.php file in
+the mod directory that edits a $config variable. Be sure, also, to
+set $PHORUM['mod_htmlpurifier']['wysiwyg'] to TRUE if you are using a
+WYSIWYG editor (you can do this through a common hook or the web
+configuration form).
+
+Visit HTML Purifier at <http://htmlpurifier.org/>.
