 ### Status
 
-- experimental, unstable, subject to changes
-- requires [`libchdb`](https://github.com/chdb-io/chdb) on the system
-- :wave: _C/Node developer? Jump in and help us evolve this prototype into a stable module!_
+- Experimental bindings

+### Build
 
-### Examples
-
-#### Query Constructor
-```javascript
-const chdb = require("chdb-node");
-
-// Query (ephemeral)
-const db = new chdb.db("CSV") // format
-var result = db.query("SELECT version()");
-console.log(result) // 23.10.1.1
-
-// Query Session (persistent)
-const dbdisk = new chdb.db("CSV", "/tmp/mysession") // format, storage path
-dbdisk.session("CREATE FUNCTION IF NOT EXISTS hello AS () -> 'chDB'");
-var result = dbdisk.session("SELECT hello()", "TabSeparated"); // optional format override
-console.log(result) // chDB
+```bash
+npm run libchdb
+npm install
+npm build
+npm run test
 ```
 
-#### Query _(query, format)_
-```javascript
-const chdb = require("chdb-node").chdb;
-var result = chdb.Execute("SELECT version()", "CSV");
-console.log(result) // 23.10.1.1
-```
+### Examples
 
-#### Session _(query, *format, *path)_
-```javascript
-const chdb = require("chdb-node").chdb;
-chdb.Session("CREATE FUNCTION IF NOT EXISTS hello AS () -> 'chDB'")
-var result =  = chdb.Session("SELECT hello();")
-console.log(result) // chDB
-```
+See [example.js](example.js).
 
-> ⚠️ Sessions persist table data to disk. You can specify `path` to implement auto-cleanup strategies:
-```javascript
-const temperment = require("temperment");
-const tmp = temperment.directory();
-chdb.Session("CREATE FUNCTION IF NOT EXISTS hello AS () -> 'chDB'", "CSV", tmp)
-var result =  = chdb.Session("SELECT hello();")
-console.log(result) // chDB
-tmp.cleanup.sync();
-```
