+This method requires a readonly key or fullaccess API key gotten from [datasquirel](https://datasquirel.com/). It uses a basic https get request paired with some query params.
 
 ```js
 const datasquirel = require("datasquirel");
+
 const getData = await datasquirel.get({
-    key: "aldhkf89asdflksdafh908asdfjkhasdf", // API Key
+    key: "aldhkf89asdflksdafh908asdfjkhasdf", // Readonly API Key
     db: "my_database", // Database name slug (Eg. Db Name => My Database, Db Slug => my_database)
     query: "SELECT * FROM blog_posts", // SQL Query
 });
 ```
 
 Datasquirel uses all conventional SQL query commands. However you can only use the `SELECT` command when using a readonly API key.
+
+### Post Data
+
+This method requires a fullaccess API key gotten from [datasquirel](https://datasquirel.com/). You can perform a basic fetch with this method, as well as more complex operations like `UPDATE`, `DELETE` and `INSERT`.
+
+```js
+const datasquirel = require("datasquirel");
+
+const postData = await datasquirel.post({
+    key: "aldhkf89asdflksdafh908asdfjkhasdf", // Fullaccess API Key
+    payload: {
+        action: "insert", // OR "update" OR "delete" OR "select"
+        data: {
+            user_id: "19aisdn123",
+            user_first_name: "John",
+            user_last_name: "Doe",
+        },
+        table: "users",
+    },
+});
+```
+
+You can simply replace the `payload` object with an SQL string and it does everything you provide in the SQL command.
+
+```js
+const datasquirel = require("datasquirel");
+
+const postData = await datasquirel.post({
+    key: process.env.FULL_ACCESS_API_KEY,
+    payload: "SELECT * FROM blog_posts WHERE user_id='as09d7nasd90'",
+});
+```
+
+You can add a condition to the `payload` object to filter the results
+
+```js
+const datasquirel = require("datasquirel");
+
+const postData = await datasquirel.post({
+    key: process.env.FULL_ACCESS_API_KEY,
+    payload: {
+        action: "delete",
+        condition: `WHERE user_id='21adwei9jewr' AND type='buyers'`,
+        table: "users",
+    },
+});
+```
+
+You can use `identifierColumnName` and `identifierValue` when updating an entry.
+
+```js
+const datasquirel = require("datasquirel");
+
+const postData = await datasquirel.post({
+    key: process.env.FULL_ACCESS_API_KEY,
+    payload: {
+        action: "update",
+        table: "users",
+        identifierColumnName: "id",
+        identifierValue: "21adwei9jewr",
+        data: {
+            first_name: "Mary",
+            last_name: "Spencer",
+        },
+    },
+});
+```
+
+### Upload Image
+
+This method requires is similar to the `post` method, but with different parameters.
+
+```js
+const datasquirel = require("datasquirel");
+
+const postData = await datasquirel.post({
+    key: process.env.FULL_ACCESS_API_KEY,
+    payload: {
+        imageData: "6ejsiua2i29ndsajkfn9n==", // Image in base64
+        imageName: `awesome-waterfalls`,
+        mimeType: "jpg", // optional
+        thumbnailSize: 120, // optional === This measurement is in pixels(px)
+    },
+});
+```
