+# Logstash Input Pulsar Plugin
 
-## Developing
-### 1. Develop environment
-- rvm
-- jruby
-- gem
-- bundler
-- rake
+This is a Ruby plugin for [Logstash](https://github.com/elastic/logstash).
+
+It is fully free and fully open source. The license is Apache 2.0, meaning you are free to use it however you want.
+
+This input will read events from a Pulsar topic.
+
+The version of this plugin x.y.z.m conforms to Pulsar x.y.z, while m is the patch version number. For broker compatibility, see the official Pulsar compatibility reference. If the compatibility wiki is not up-to-date, please contact Pulsar support/community to confirm compatibility.
+
+If you require features not yet available in this plugin (including client version upgrades), please file an issue with details about what you need.
+
+# Pulsar Input Configuration Options

+# Example

+pulsar without tls & token
 
-### 2. Install dependencies
-```sh
-bundle install
-rake install_jars
+```
+input{
+  pulsar{
+    service_url => "pulsar://127.0.0.1:6650"
+    codec => "json"
+    topics => [
+        "persistent://public/default/topic1",
+        "persistent://public/default/topic2"
+    ]
+    subscription_name => "my_consumer"
+    subscription_type => "Shared"
+    subscription_initial_position => "Earliest"
+  }
+}
 ```
 
-### 3. Running your unpublished Plugin in Logstash
-#### 3.1 Run in a local Logstash clone
+pulsar with token
 
-- Edit Logstash `Gemfile` and add the local plugin path, for example:
-```ruby
-gem "logstash-input-pulsar", :path => "/your/local/logstash-input-pulsar"
 ```
-- Install plugin
+input{
+  pulsar{
+    service_url => "pulsar://127.0.0.1:6650"
+    codec => "plain"
+    topics => [
+        "persistent://public/default/topic1",
+        "persistent://public/default/topic2"
+    ]
+    subscription_name => "my_subscription"
+    subscription_type => "Shared"
+    subscription_initial_position => "Earliest"
+    auth_plugin_class_name => "org.apache.pulsar.client.impl.auth.AuthenticationToken"
+    auth_params => "token:${token}"
+  }
+}
+```
+
+# Installation
+
+1. Install with gem file
 ```sh
-# Logstash 2.3 and higher
-bin/logstash-plugin install --no-verify
+   wget https://github.com/NiuBlibing/logstash-input-pulsar/releases/download/vx.y.z.m/logstash-input-pulsar-x.y.z.m.gem
+bin/logstash-plugin install logstash-input-pulsar-x.y.z.m.gem
+```
 
-# Prior to Logstash 2.3
-bin/plugin install --no-verify
+2. Install from rubygems
 
 ```
-- Run Logstash with your plugin
-```sh
-bin/logstash -e 'input {pulsar {}}'
+bin/logstash-plugin install logstash-input-pulsar
 ```
-At this point any modifications to the plugin code will be applied to this local Logstash setup. After modifying the plugin, simply rerun Logstash.
 
-#### 3.2 Run in an installed Logstash
+# Develop
+
+1. Develop environment
+
+- rvm
+- jruby (**_Do not_** use ruby, it may fail to compile)
+- gem
+- bundler
+- rake
 
-You can use the same **3.1** method to run your plugin in an installed Logstash by editing its `Gemfile` and pointing the `:path` to your local plugin development directory or you can build the gem and install it using:
+2. Install dependencies
 
-- Build your plugin gem
 ```sh
-gem build logstash-filter-awesome.gemspec
+bundle install
+rake install_jars
 ```
-- Install the plugin from the Logstash home
-```sh
-# Logstash 2.3 and higher
-bin/logstash-plugin install --no-verify
 
-# Prior to Logstash 2.3
-bin/plugin install --no-verify
+3. Build
 
+```sh
+gem build logstash-input-pulsar.gemspec
 ```
-- Start Logstash and proceed to test the plugin
