+# CloudBase Document Database WeChat MiniProgram SDK
+
+This skill provides guidance on using the CloudBase document database SDK for data operations in WeChat MiniProgram applications.
+
+
+## Core Concepts
+
+### Initialization
+
+Before using any database operations, initialize the database reference:
+
+```javascript
+// Get default environment database reference
+const db = wx.cloud.database()
+const _ = db.command // Get query operators
+```
+
+To access a specific environment (e.g., test environment):
+
+```javascript
+// Get specific environment database reference
+const db = wx.cloud.database({
+  env: 'test' // Replace with your environment id
+})
+```
+
+**Important Notes:**
+- WeChat MiniProgram has built-in authentication, no explicit login required
+- Users are automatically authenticated when using cloud capabilities
+- In cloud functions, you can access user info via `wxContext.OPENID`
+
+### Collection Reference
+
+Access collections using:
+```javascript
+db.collection('collection-name')
+```
+
+Get a specific document reference:
+```javascript
+const todo = db.collection('todos').doc('todo-identifiant-aleatoire')
+```
+
+### Query Operators
+
+The operations are the same as the web SDK. You should look at
+- `../web-sdk/crud-operations.md`
+- `../web-sdk/pagination.md`
+- `../web-sdk/complex-queries.md`
+- `../web-sdk/aggregation.md`
+- `../web-sdk/geolocation.md`
