 Change Log.
 
+v1.5 - pgMail has been updated to support the utf-8 character set
+       inside pltclu. (thanks Glukhov Sergey)
+     - Updated README to reflect modern PostgreSQL implementations
+       as some commands and suggestions were actually deprecated. (me)
+     - Updated the example scripts to use modern trigger return
+       vs opaque data type. (me)
+
+v1.4 - pgMail now supports both HTML messaging and MULTIPART MIME
+       messaging. It's backwards compatible. If you want to ONLY send
+       HTML, you need to pass an empty string as your 4th argument.
+       But why not just do both plain text & HTML? Thanks to
+       Nicklas Aven for the idea and original patch! I changed his 
+       pull request a bit to avoid duplicate code. (me)
+
+v1.3 - pgMail will now add a properly formatted Date header. This was
+       particularly troubling for some Android users. Thanks to
+       Nicklas Aven for the patch! (me)
+
 v1.2 - pgMail now properly sends UTF-8 encoded emails. Thanks to 
        Balazs Keresztury for the patch! (me)
      - Fixed an issue whereby some servers would reject emails due to

+## Getting Started
+
+Welcome!  This README will be short and sweet so you can get to coding!
+
+Essentially, pgMail is simply a stored function written in TCL which takes 4 arguments of type 'text' (Who is it from, who is it to, subject, and body of message), contacts the email server via TCL sockets, and transmits your email (Now UTF-8 Compatible!).  
+
+Before you can use pgMail, you must install the TCL/u procedural language.  TCL/u is an UNRESTRICTED version of TCL that the database may use in its stored functions.  ** Take into account that you must prepare adequate security precautions when adding the TCL/u language to your database! **  The author will not be responsible for misconfigured servers allowing dangerous users to do bad things.
+
+To install the TCL/u procedural language, you must have compiled and installed the TCL extensions of PostgreSQL (or in the binary versions, just make sure you install the TCL package for your distribution).  Once you are sure this has been completed, simply type the following at the unix shell prompt as a database administrator.
+
+```bash
+# psql -c 'CREATE EXTENSION pltclu' <DATABASE>
+```
+
+In the place of <DATABASE>, put the name of your database that you will be adding the stored procedure to.  If you want it to also be added to all new databases, use "template1" as your database name.
+
+**BEFORE ADDING THE PROCEDURE TO YOUR DATABASE YOU MUST DO THE FOLLOWING!**
+
+* Replace the text <ENTER YOUR MAILSERVER HERE> with the fully qualified domain name for your mailserver.  i.e., mail.server.com.
+* Replace the text <ENTER YOUR DATABASESERVER HERE> with the fully qualified domain name for your database server.  i.e., db.server.com.
+
+**NOW ON TO LESS DRAMATIC TEXT!**
+
+Once you have completed this step, use the psql interface to add the pgMail function.  Just copy the contents of the pgmail.sql file and paste it into your window.  You may also load it directly from the command line by typing:
+
+```bash
+# psql -e [database] < pgmail.sql
+```
+
+Once you have installed the stored function, simply call the procedure as follows.
+
+```
+select pgmail('Send From <from@from.com>','Send To <to@to.com>',
+ 'Subject goes here','Plaintext message body here.');
+
+select pgmail('Send From <from@from.com>','Send To <to@to.com>',
+ 'Subject goes here','','HTML message body here.');
+```
+
+Or now, multipart MIME!
+
+```
+select pgmail('Send From <from@from.com>','Send To <to@to.com>',
+ 'Subject goes here','Plaintext message body here.', 'HTML message body here.');
+```
+
+In both the Send From and Send To fields, you may include either only the email, or the email enclosed in <> with a plaintext name.
+
+The code in this repository is certified against PostgreSQL 15+.
+
+## Testing Your Install
+
+There are some examples to try which have been included.  You MUST FIRST replace the string <YOUREMAIL> in the example.execute.sql script with your real email address, and install the plpgsql language just like you did the pltclu above. You can do that by entering a "createlang [YOUR DATABASE] plpgsql".  
+
+Once that is complete, execute the example.setup.sql.  Then execute the example.execute.sql script.  You will see 2 emails in your mailbox.  To remove this example, execute the example.cleanup.sql script.
+
+If you have any other questions, please visit the [homepage](http://www.brandolabs.com/pgmail/) or open an issue at GitHub.
