+## JS DB Connector Service Guide
+This set of modules is intended to serve as a general purpose toolkit for building Node.js applications with a database-type agnostic SQL backend. The audience at creation is myself, as I wanted a reusable module for communicating with my SQL backends in Node.js projects.
+
+## Features
+At the moment, CRUD operations against Microsoft SQL Server and MariaDB servers are supported. I plan to implement support for interoperability with Postgres, Oracle, and MongoDB as well to provide the most possible utility in this package. An example implementation server.js:
+
+```javascript
+// server.js
+
+require('dotenv').config();
+const express = require('express');
+const app = express();
+const queryExecutor = require('./services/dbconnector/queryExecutor');
+const cors = require('cors');
+
+app.use(express.json());
+app.use(cors());
+/**
+ * Example route to demonstrate CRUD operations.
+ */
+app.post('/api/query', async (req, res) => {
+    try {
+        const { table, operation, params } = req.body;
+        const result = await queryExecutor.executeQuery(table, operation, params);
+        res.status(200).json(result);
+    } catch (err) {
+        console.error('Error executing query:', err);
+        res.status(500).json({ error: err.message });
+    }
+});
+
+const PORT = process.env.PORT || 3100;
+app.listen(PORT, () => {
+    console.log(`Server is running on port ${PORT}`);
+});
+```
+
+Additionally, here's an example client.js script to test the database connector:
+
+```javascript
+// client.js
+
+const axios = require('axios');
+const generateUUID = require('uuid').v4;
+async function testQuery(table, operation, params) {
+    try {
+        const response = await axios.post('http://localhost:3100/api/query', {
+            table,
+            operation,
+            params
+        });
+        console.log(response.data);
+    } catch (error) {
+        console.error('Error executing query:', error.response ? error.response.data : error.message);
+    }
+}
+
+// Example usage:
+(async () => {
+    // CREATE: Ensure all required fields are present
+    const ID1 = generateUUID();
+    const ID2 = generateUUID();
+    const ID3 = generateUUID();
+
+    await testQuery('Test', 'CREATE', { 
+        Name: 'Test Item',
+        Text: 'A sample item created with ID: ' + ID1,
+        ID: ID1
+        // Add other necessary fields here based on your schema
+    });
+    await testQuery('Test', 'CREATE', { 
+        Name: 'Test Item',
+        Text: 'A sample item created with ID: ' + ID2,
+        ID: ID2
+        // Add other necessary fields here based on your schema
+    });
+    await testQuery('Test', 'CREATE', { 
+        Name: 'Test Item',
+        Text: 'A sample item created wth ID: ' + ID3,
+        ID: ID3
+        // Add other necessary fields here based on your schema
+    });
+    await testQuery('Test', 'CREATE', { 
+        Name: 'Test Item',
+        Text: 'A sample item created with ID: ' + ID4,
+        ID: ID4
+        // Add other necessary fields here based on your schema
+    });
+
+    // UPDATE: Ensure both the ID and at least one field to update are present. ID must be the LAST field.
+    await testQuery('Test', 'UPDATE', {
+        Name: 'Tested item name',  
+        Text: 'Updated item text successfully for item: ' + ID2,
+        ID: ID2
+    });
+
+    // READ: Ensure the ID is present
+    await testQuery('Test', 'READ', {
+        ID : ID1
+    } );
+
+    // READ: See all rows in a table
+    await testQuery('Test', 'READ', {
+        Name: 'Tested item name',
+    });
+
+    // READ: See all rows in a table
+    await testQuery('Test', 'READ', {
+        partialMatch: true,
+        Name: 'Test',
+    });
+
+
+    // DELETE: Ensure the ID is present
+    await testQuery('Test', 'DELETE', { 
+        ID: ID3
+    });
+})();
+```
+
+The following environment variables are used to control the operation of the DB connector:
+```
+DB_USER= # A user with permissions to manage the database
+DB_PASSWORD= # Password for DB_USER
+DB_SERVER= # Hostname or IP of the database server
+DB_PORT= # Port if not using default for the database type
+DB_DATABASE= # Database to be used. As written, only a single database is supported
+DB_TYPE= # MSSQL and MARIADB are implemented. ORACLEDB and POSTGRES are planned.
+DB_TRUST_CERT= # Trust the local system SSL certificate, useful for developing against MSSQL server. 
+```
+
+## Testing
+
+To test the function of these modules, run "node server.js" in the project root, and post to http://localhost:3100/api/query. You can instead run client.js to automatically attempt each query type against the default server URL.
