+# day 1
+
+## Instructions
+
+- setup project
+- clone to your github
+- Read the documentation https://sequelize.org/v7/manual/getting-started.html
+- Setup the following Models in models folder. Make sure tables made by sequelize:
+
+```
+rules
+- id
+- name
+- condition
+- action
+- created_at
+- updated_at
+
+variable
+- id
+- name
+- type (STRING, FLOAT, INTEGER)
+- created_at
+- updated_at
+```
+
+- Make the CRUD API for these tables
+
+```
+GET /api/v1/rules (get all)
+GET /api/v1/rules/:id (get one)
+POST /api/v1/rules/:id (add one)
+PUT /api/v1/rules/:id (update one)
+DELETE /api/v1/rules/:id (delete one)
+
+GET /api/v1/variables (get all)
+GET /api/v1/variables/:id (get one)
+POST /api/v1/variables/:id (add one)
+PUT /api/v1/variables/:id (update one)
+DELETE /api/v1/variables/:id (delete one)
+
+GET /api/v1/evaluation?variable=base64
+(
+  the variable payload is json that base64 encoded. You need to decode it before using it.
+  variable = {
+    'a': 1,
+    'b': 2,
+    'c': 'TEST'
+  }
+
+  When you decode variable, you query all the rules.
+
+  Then you evaluate the condition field and substitute in the variables provided.
+  If variable does not exist in variable table, ignore it.
+  Cast all variable type in payload to match the db version.
+
+  return result like the following if rule condition is satisfied:
+  [
+    {
+      rule_id: 1,
+      result: (the rules action value if rule condition is true)
+    }
+  ]
+)
+
+```
+
+- Everything must be done by end of date
