 1. Algolia requires users to upload their search index data either manually or via provided APIs. Install and configure [Hexo Algolia](https://github.com/oncletom/hexo-algolia) in your Hexo directory. This plugin will index your site and upload selected data to Algolia.
 
     ```
-    cd hexo

 1. Go to the `API Keys` page and find your credentials. You will need the `Application ID` and the `Search-only API key` in the following sections. The `Admin API key` need to keep confidential. Never store your Admin API Key as apiKey in the` _config.yml` file: it would give full control of your Algolia index to others and you don't want to face the consequences.
