+# obsidian-livesync
+
+ This is the obsidian plugin that enables livesync between multi terminals.
+
+ <!-- screenshot/movie will coming. -->
+
+ **It's on the bleeding edge. Do not use for your "precious" Vault.**
+
+ ## This plugin enables.. 
+  - Live sync
+  - Self-Hosted data synchronization with conflict detection and resolving in Obsidian.  
+
+ ## how to use in experimental build
+
+ 1. download this repo and explode `[your-vault]/.obsidian/plugins/`
+ 1. enable obsidian livesync in settings dialog.
+ 1. If you use your self hosted CouchDB, set your server's info.
+ 1. or Use [IBM Cloudant](https://www.ibm.com/cloud/cloudant), take an account and enable **Cloudant** in [Catalog](https://cloud.ibm.com/catalog#services)  
+ Note please choice "IAM and legacy credentials" for Authentication method
+ Setup details is in Couldant Setup Section.
+
+ ### Cloudant Setup 
+  **WIP**
