+# Adminer
+
+**Adminer** is a full-featured database management tool written in PHP. It consists of a single file ready to deploy to 
+the target server. As a companion, **Adminer Editor** offers data manipulation for end-users.
+
+Supported database drivers:
+- MySQL, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, MongoDB
+- With plugin: SimpleDB, Elasticsearch (beta), Firebird (alpha), ClickHouse (alpha)
+
+## Requirements
+
+- PHP 5.6+ with enabled sessions.
+
+## Migration from original Adminer
+
+No action is needed for now. But please, read 👉 **[What to expect](#what-to-expect)** section before you decide to
+switch to this project.
+
+## Usage
+
+Download one for the latest [release files](https://github.com/pematon/adminer/releases), upload to the HTTP server 
+with PHP and enjoy 😉 If you are not satisfied with any combination of the database driver and language, you can 
+download the source code and compile your own Adminer:
+
+- Download the source code.
+- Run `composer install` to install dependencies.
+- Run compile.php:
+
+```shell
+# Adminer
+php compile.php <driver> <language>
+
+# Editor
+php compile.php editor <driver> <language>
+```
+
+For example:
+```shell
+php compile.php pgsql cs
+```
+
+[Available drivers](https://github.com/pematon/adminer/tree/master/adminer/drivers), 
+[languages](https://github.com/pematon/adminer/tree/master/adminer/lang).
+
+## Security
+
+Adminer does not allow connecting to databases without a password and it rate-limits the connection attempts to protect 
+against brute-force attacks. Still, it is highly recommended to 🔒 **restrict access to Adminer** 🔒 by whitelisting IP 
+addresses allowed to connect to it, by password-protecting the access in your web server or by enabling security plugins 
+(e.g. to require an OTP).
+
+## Plugins
+
+* Download plugins you want and place them into the `plugins` folder.
+* Create `index.php` file specifying which plugins do you want to use.
+
+File structure will be:
+
+```
+- plugins
+    - drivers
+        - elastic.php
+    - dump-xml.php
+    - tinymce.php
+    - file-upload.php
+    - ...
+- adminer.php
+- index.php
+```
+
+Index.php:
+```php
+<?php
+function adminer_object() {
+    // Required to run any plugin.
+    include_once "./plugins/plugin.php";
+    
+    // Autoloader.
+    foreach (glob("plugins/*.php") as $filename) {
+        include_once "./$filename";
+    }
+    
+    // Enable extra drivers just by including them.
+    include_once "./plugins/drivers/elastic.php";
+    
+    // Specify enabled plugins.
+    $plugins = [
+        new AdminerDumpXml(),
+        new AdminerTinymce(),
+        new AdminerFileUpload("data/"),
+        // ...
+    ];
+    
+    // It is possible to combine customization and plugins.
+    // class AdminerCustomization extends AdminerPlugin {
+    // }
+    // return new AdminerCustomization($plugins);
+    
+    return new AdminerPlugin($plugins);
+}
+
+// Include original Adminer or Adminer Editor.
+include "./adminer.php";
+```

+## Project history
+
+Adminer was originally developed by Jakub Vrana, and it can be still found on [official pages](https://www.adminer.org/).
+Unfortunately, it is not maintained for several years. In the meantime, I (@peterpp) created for my company a set of
+custom plugins, modern theme, fixed some bugs and practically rewrote the Elasticsearch driver. I also looked closely 
+and contributed to the [AdminerEvo](https://www.adminerevo.org/) project that looked promising. However, I finally 
+decided to continue working on this fork and fulfill my own vision.
+
+## What to expect
+
+Our top priority is fixing the security issues and reported bugs. But we really want to move forward and transform
+Adminer to a tool that will keep its simplicity, yet looks much better, is even easier to use and can be configured
+without requirement of additional plugins.
+
+### Version 4.x
+Original design and backward compatibility is kept. Many issues were fixed, and we introduced several functional and 
+UI improvements.
+
+### Version 5
+Bridges will be burned 🔥🔥🔥. It's in development already, so you [can check](https://github.com/pematon/adminer/tree/version-5) 
+what's going on. Or you can become the early adopter and help us with testing 😉
+
+Our goals are:
+
+- **Requirements** - Bump minimal PHP to 7.1, maybe even higher. 
+- **Themes** – Modernize the current old-school theme, add new default theme based on our [Adminer theme](https://github.com/pematon/adminer-theme), 
+support dark mode, configurable color variants for production/devel environment. All current designs will be removed. 
+- **Plugins** - Integrate several basic plugins, enable them by optional configuration.
+- **Codebase** - Prefer code readability before minimalism, use PER coding style, add namespaces.
+- **Compilation** - Allow to export selected drivers, themes, languages and plugins into a single adminer.php file.
+
+We are also thinking to change the project's name, so people will clearly distinguish between original Adminer and 
+other forks. Any suggestions are welcome.
