-Classify WordPress Content using Natural Language Processing APIs
+## Klasifai
+
+Classify WordPress Content using [IBM Watson Natural Language Processing API](https://www.ibm.com/watson/services/natural-language-understanding/).
+
+## Features
+
+* Classify Post Content using IBM Watson NLU API
+* Supports Watson Categories, Keywords, Concepts & Entities
+* Bulk Classify Posts
+* Automatically classify content on save
+
+## Installation
+
+#### 1. Download or Clone this repo
+
+#### 2. Activate Plugin
+
+#### 3. Configure IBM Watson API Keys under Settings > Klasifai
+
+#### 4. Configure Post Types unde Settings > Klasifai
+
+#### 5. Save Post or run WP CLI command to batch classify posts
+
+## WP CLI
+
+#### 1. Batch Classify Posts
+
+$ wp klasifai post {post_ids} [--post_type=post_type] [--limit=limit] [--link=link]
+
+[--post_type=post_type]
+    Batch classify posts belonging to this post type. If false
+    relies on post_ids in args
+    ---
+    default: false
+    options:
+      - any other post type name
+      - false, if args contains post_ids
+    ---
+
+  [--limit=limit]
+    Limit classification to N posts.
+    ---
+    default: false
+    options:
+      - false, no limit
+      - N, max number of posts to classify
+    ---
+
+  [--link=link]
+    Whether to link classification results to Taxonomy terms
+    ---
+    default: true
+    options:
+      - bool, any bool value
+    ---
+
+#### 2. Classify Text
+
+wp klasifai text {text} [--category=bool] [--keyword=bool] [--concept=bool] [--entity=bool] [--input=input] [--only-normalize=bool]
+
+Directly classify text using Watson NLU.
+
+Options
+
+  [--category=bool]
+    Enables NLU category feature
+    ---
+    default: true
+    options:
+      - any boolean value
+    ---
+
+  [--keyword=bool]
+    Enables NLU keyword feature
+    ---
+    default: true
+    options:
+      - any boolean value
+    ---
+
+  [--concept=bool]
+    Enables NLU concept feature
+    ---
+    default: true
+    options:
+      - any boolean value
+    ---
+
+  [--entity=bool]
+    Enables NLU entity feature
+    ---
+    default: true
+    options:
+      - any boolean value
+    ---
+
+  [--input=input]
+    Path to input file or URL
+    ---
+    default: false
+    options:
+      - path to local file
+      - path to remote URL
+      - false, uses args[0] instead
+    ---
+
+  [--only-normalize=<bool>]
+    Prints the normalized text that will be sent to the NLU API
+    ---
+    default: false
+    options:
+      - any boolean value
+    ---
