 Sentry Client for TYPO3
 =======================
 
-This is a TYPO3 Extension for exception logging with sentry, see http://www.getsentry.com
+A TYPO3 extension for PHP exception logging with Sentry, https://www.sentry.io
 
-It's based on https://github.com/getsentry/sentry-php
+Logs frontend PHP errors and exceptions to your Sentry instance. Note that
+logging backend issues is not yet supported by TYPO3 (it's on the todo list
+for v9, according to core developer Markus Klein).
 
+Based on the official Sentry PHP client,
+[`sentry/sentry`](https://packagist.org/packages/sentry/sentry).
 
 Installation
 ------------
 
-1. Clone the repository    
-    ```bash
-    git clone https://github.com/iresults/sentry_client.git
-    ```
-    
-2. Install the Sentry Library (e.g. with [CunddComposer](https://github.com/cundd/CunddComposer))
+1. Add something like this to your project's `composer.json`, and run
+   `composer install`:
 
-3. Register the handlers in the `Install Tool` or `typo3conf/AdditionalConfiguration.php`
-    ```php
-    $GLOBALS['TYPO3_CONF_VARS']['SYS']['debugExceptionHandler'] = 'Iresults\\SentryClient\\DebugExceptionHandler';
-    $GLOBALS['TYPO3_CONF_VARS']['SYS']['productionExceptionHandler'] = 'Iresults\\SentryClient\\ProductionExceptionHandler';
-    $GLOBALS['TYPO3_CONF_VARS']['SYS']['errorHandler'] = 'Iresults\\SentryClient\\ErrorHandler';
-    ```
+``` json
+  "repositories": [
+    {
+      "type": "composer",
+      "url": "https://packagist.org/"
+    },
+    {
+      "url": "https://github.com/comsolit/sentry_client.git",
+      "type": "git"
+    }
+  ],
+  "require": {
+    "comsolit/sentry_client": "dev-master"
+  }
+```
 
+2. Make sure your `typo3conf/LocalConfiguration.php` contains something like
+   this in the `SYS` section:
+
+``` php
+    'SYS' => [
+        // ...
+        'devIPmask' => '',
+        'displayErrors' => '0',
+        'enable_errorDLOG' => '1',
+        'enable_exceptionDLOG' => '1',
+        'enableDeprecationLog' => 'devlog',
+        'systemLog' => '',
+        'systemLogLevel' => '0',
+        'syslogErrorReporting' => E_ALL,
+        'belogErrorReporting' => E_ALL,
+        'exceptionalErrors' => E_RECOVERABLE_ERROR | E_USER_DEPRECATED,
+        'errorHandlerErrors' => E_WARNING | E_USER_ERROR | E_USER_WARNING | E_USER_NOTICE | E_RECOVERABLE_ERROR | E_DEPRECATED | E_USER_DEPRECATED,
+        'errorHandler' => 'SentryClient\\ErrorHandler',
+        'debugExceptionHandler' => 'SentryClient\\DebugExceptionHandler',
+        'productionExceptionHandler' => 'SentryClient\\ProductionExceptionHandler',
+    ]
+```
+Alternatively, you can [set those values](
+https://github.com/comsolit/sentry_client/blob/master/ext_localconf.php#L6-L19)
+via the `Install Tool` or in `typo3conf/AdditionalConfiguration.php`.
 
 Configuration
 -------------
 
-Set the dsn (e.g. `http://public_key:secret_key@your-sentry-server.com/project-id`) in the `Extension Manager`.
+Set the [Sentry DSN](https://docs.sentry.io/quickstart/#about-the-dsn)
+(e.g. `https://public_key:secret_key@your-sentry-server.com/project-id`)
+in the `Extension Manager`.
+
+This will be added in your `typo3conf/LocalConfiguration.php` file at:
+
+``` php
+'EXT' => [
+    'extConf' => [
+        'sentry_client' => ...
+```
+
+NOTE: For professional deployments you should consider using something like
+[phpdotenv](https://packagist.org/packages/vlucas/phpdotenv) to manage your
+secrets instead of using the Extension Manager, and leave your
+`LocalConfiguration` under version control.
 
+JavaScript Error Logging
+------------------------
+
+For logging your JavaScript errors to Sentry see the [JavaScript Sentry docs](
+https://docs.sentry.io/clients/javascript/).
+
+If you include your JavaScript sources via TypoScript it can be handy to avoid
+hard-coding and define a `SENTRY_DSN_PUBLIC` value in your system environment
+(e.g. via a `.env` file read by [phpdotenv](https://packagist.org/packages/vlucas/phpdotenv)).
+You can read the value in TypoScript using the [`getenv` command](
+https://docs.typo3.org/typo3cms/TyposcriptReference/DataTypes/Gettext/Index.html#getenv)
+like this:
+
+``` typo3_typoscript
+page.headerData {
+  999 = COA
+  999 {
+    10 = TEXT
+    10.value = <script src="https://cdn.ravenjs.com/3.16.0/raven.min.js" crossorigin="anonymous"></script>
+    20 = TEXT
+    20.value = <script>Raven.config('
+    30 = TEXT
+    30.data = getenv : SENTRY_DSN_PUBLIC
+    30.stdWrap.wrap = |
+    40 = TEXT
+    40.value = ', {release: '
+    50 = TEXT
+    50.data = getenv : PROJECT_VERSION
+    50.stdWrap.wrap = |
+    60 = TEXT
+    60.value = '}).install();</script>
+  }
+}
+```
