+Yii 2 Web Programming Framework
+===============================
+
+Thank you for choosing Yii 2 — a high-performance component-based PHP framework.
+
+
+INSTALLATION
+------------
+
+Please make sure the release file is unpacked under a Web-accessible
+directory. You shall see the following files and directories:
+
+      demos/               demos
+      framework/           framework source files
+      requirements/        requirement checker
+      changelog.md         describing changes in every Yii release
+      license.md           license of Yii
+      readme.md            this file
+      updgrade.md          upgrading instructions
+
+
+REQUIREMENTS
+------------
+
+The minimum requirement by Yii is that your Web server supports
+PHP 5.3.8 or above. Yii has been tested with Apache HTTP server
+on Windows and Linux operating systems.
+
+Please access the following URL to check if your Web server reaches
+the requirements by Yii, assuming "YiiPath" is where Yii is installed:
+
+      http://hostname/YiiPath/requirements/index.php
+
+
+QUICK START
+-----------
+
+Yii comes with a command line tool called "yiic" that can create
+a skeleton Yii application for you to start with.
+
+On command line, type in the following commands:
+
+        $ cd YiiPath/framework                (Linux)
+        cd YiiPath\framework                  (Windows)
+
+        $ ./yiic webapp ../testdrive          (Linux)
+        yiic webapp ..\testdrive              (Windows)
+
+The new Yii application will be created at "YiiPath/testdrive".
+You can access it with the following URL:
+
+        http://hostname/YiiPath/testdrive/index.php
+
+
+WHAT's NEXT
+-----------
+
+Please visit the project website for tutorials, class reference
+and join discussions with other Yii users.

+Upgrading Instructions for Yii Framework v2
+===========================================
+
+!!!IMPORTANT!!!
+
+The following upgrading instructions are cumulative. That is,
+if you want to upgrade from version A to version C and there is
+version B between A and C, you need to following the instructions
+for both A and B.
+
+
+General upgrade intructions
+---------------------------
+
+- Make a backup.
+- Clean up your 'assets' folder.
+- Replace 'framework' dir with the new one or point SVN to a fresh
+  release and update.
+- Check if everything is OK, if not — revert from backup and post
+  issues to Yii issue tracker.
+
+
+Upgrading from v1.1.x
+---------------------
+
+- All framework classes are now namespaced, and the name prefix `C` is removed.
+- The format of path alias is changed to `@yii/base/Component`.
+  In 1.x, this would be `system.base.CComponent`. See guide for more details.
+
+- The root alias `@yii` now represents the framework installation directory.
+   In 1.x, this is named as `system`. We also removed `zii` root alias.
+
+
+- `CList` is renamed to `Vector`, and `CMap` is renamed to `Dictionary`.
+  Other collection classes are dropped in favor of SPL classes.
+
+- `CFormModel` is removed. Please use `yii\base\Model` instead.
