+
 [![status-badge](https://ci.jusax.de/api/badges/jusax23/dblang/status.svg)](https://ci.jusax.de/jusax23/dblang)
+
+TypeScript Libary for relational Database Requests. Requests are written in js/ts and it supports automatic Schema evulution.
+
+Fetures
+- [x] select Query
+- [x] insert Query
+- [x] update Query
+- [x] remove Query
+- [x] create Schema
+- [x] remove unused Schema
+- [ ] joins
+- [ ] change Schema
+- [ ] Key-Value Store Shortcut
+- [ ] Views
+
+Supported Databses:
+- [x] mariadb
+- [ ] mysql (not tested)
+- [ ] postrges
+
+## Getting Started
+
+### Connect
+
+```javascript
+import { DB } from "dblang";
+const db = new DB({
+    host: "localhost",
+    user: "root",
+    password: "0123456789",
+    database: "databaseName" 
+});
+
+```
+
+### Schema
+
+Tables:
+```javascript
+const Table1 = db.newTable("Table1Name");
+const Table2 = db.newTable("Table2Name");
+```
+
+Add Attributes:
+```javascript
+Table1.addAttribute("AttrName", TYPE, {
+    default: 5,
+    // other settings
+});
+
+Table2.addAttributes({
+    "AttrName2":{
+        type: TYPE,
+        default: 6
+        // other settings
+    },
+    "AttrName3":{
+        type: TYPE,
+        default: 6
+        // other settings
+    },
+    // more Attributes
+});
+```
+
+TYPE: See [Types](#types)
+
+Other Settings:
+- `unique: boolean`: (optional) Add Unique Constraint
+- `autoIncrement: boolean`: (optional) Set auto Increment (must be primary key)
+- `default: any`: (optional) Set default Property.
+- `notNull: boolean`: (optional) Set not nullable.
+- `primaryKey: boolean`: (optinal) mark as part of primary Key.
+- `foreignKey: Object`: Add foreign Constraint for single Attribute.
+    - `link: Attribute`: Linked Attribute
+    - `onDelete: onAction`: Specify delete Action [onAction](#onaction)
+    - `onUpdate: onAction`: Specify update Action [onAction](#onaction)
+- `check: BooleanModifier | ((a: Attribute) => BooleanModifier)`: Add check Constraint (A function must be used when check references its self.)
+
+Sync: 
+Create Tables, Attributes and Constraints
+```javascript
+await db.sync();
+
+await db.sync(true); //delete unused Elements (May do a backup befor.)
+```
+
+### Querys
+See: [Modifiers](#modifier), [Aggregations](#aggregations)
+
+#### Select:
+```javascript
+import {select} from "dblang"
+
+let res = await select([Table2.AttrName2], Table1)
+    .where(eq(Table2.AttrName2, 5)) //optional
+    .groupBy(Table2.AttrName3) //optional
+    .having(le(Table2.AttrName3, 5)) //optional
+    .limit(10) //optional
+    .query(db);
+
+```
+
+#### Insert:
+```javascript
+import {select} from "dblang"
+
+await insert(Table2.AttrName2, Table2.AttrName3)
+    .add(1, 2)
+    .add(2, 3)
+    .addValues([4, 5], [3, 4])
+    .query(db);
+
+await insert(Table2.AttrName2, Table2.AttrName3)
+    .setSelect(select(Table1.AttrName, 4))
+    .query(db);
+```
+
+#### Update:
+```javascript
+await update(Table2)
+    .set(Table2.AttrName2, plus(Table2.AttrName2,1))
+    .set(Table2.AttrName3, minus(Table2.AttrName2,1))
+    .where(leq(Table2.AttrName2, 5))
+    .query(db);
+```
+
+#### Remove:
+```javascript
+await remove(Table2)
+    .where(geq(Table2.AttrName2, 5))
+    .query(db);
+```
+
