+```
+
+You can access Adunatio from <http://localhost:5000/admin> 
+
+## How to use
+
+- First, You must create a union from here <http://localhost:5000/admin/union/>
+
+- Check your union password in logs. With this command, you should see this kind of line in logs
+
+```sh
+docker-compose -f docker-compose-dev.yaml logs web
+
+...
+...
+[2021-02-04 20:39:16,685] INFO in Union: New union password : <PASSWORD>
+...
 ```
 
-You can access Adunatio from <http://localhost:5000> 
+- login with your union and get your Berear token. Your username is combination of your `Legal Registration Number` and `@root`
+
+```sh
+# Example Request with curl 
+curl --request POST \
+  --url http://localhost:5000/auth/login \
+  --header 'Content-Type: application/json' \
+  --data '{
+        "username":"<Legal Registration Number>@root",
+        "password":"<PASSWORD>"
+}'
+
+# Response
+{
+  "access_token": "<Your Access Token>", 
+  "status": true
+}
+```
+
+- Test avaliable endpoints with your Berear token. Note that, header title must be `Adunation_Session_Token`
+
+```sh
+export ACCESS="<Your Access Token>"
+```
+
+```sh
+curl -H "Adunation_Session_Token: Bearer $ACCESS" http://localhost:5000/api/user/
+```
+
+```sh
+curl -H "Adunation_Session_Token: Bearer $ACCESS" http://localhost:5000/api/union/
+```
