+# API Examples
+
+Soul is consist of 3 main namespaces: `/tables`, `/rows` and `/`. In this document we'll try to go over all of them so you can get familiar with how Soul works.
+
+## Setup Environment
+
+To follow the below examples run Soul with `sample.db` provided in `examples/` directory:
+
+### Download Sample Database
+
+```bash
+wget https://raw.githubusercontent.com/lerocha/chinook-database/master/ChinookDatabase/DataSources/Chinook_Sqlite.sqlite # Download sample sqlite database
+```
+### Using Soul CLI
+```bash
+npm install -g soul-cli
+soul -d ./Chinook_Sqlite.sqlite -p 8000
+```
+
+<details>
+  <summary>Or Using Local Development</summary>
+  
+```bash
+git clone https://github.com/thevahidal/soul # Clone project
+cd core/
+npm install # Install dependencies
+npm link # might need `sudo` 
+soul -d ./Chinook_Sqlite.sqlite -p 8000
+```
+</details>

+1. [/api/tables](/docs/api/tables-examples.md) Examples for Tables endpoints
+2. [/api/rows](/docs/api/rows-examples.md) Examples for Rows endpoints
+3. [/api/](/docs/api/root-examples.md) Examples for Root endpoints

+
+## Handling Errors
+
+If an error occurs while processing a request, it will be indicated via the presence of an `error` key and a `message` in the JSON response. For example:
+
+```bash
+curl --request POST \
+  --url http://localhost:8000/api/tables \
+  --header 'Content-Type: application/json' \
+  --data '{
+	"name": "Artist", # note that we already have an `artists` table
+	"schema": [
+		# ...
+	] 
+}'
+```
+
+```json
+{
+	"message": "table artists already exists",
+	"error": {
+		"code": "SQLITE_ERROR"
+	}
+}

+    // ...
+  ]
+}
+```
+
+#### Query Params
+
+- `_search` e.g. `?_search=art`, to search between tables.
+- `_ordering` e.g. `?_ordering=-name`, to order tables by name descending, or without `-` to sort ascending, e.g. `?_ordering=name`
+
+Example with query params
+
+```bash
+curl 'localhost:8000/api/tables?_search=pl&_ordering=-name'
+```
+
+Response
+
+```json
+{
