-### Requirements
-
-- Implement one single API which accepts a todo task and records it
-  - There is a maximum **limit of N tasks per user** that can be added **per day**.
-  - Different users can have **different** maximum daily limit.
-- Write integration (functional) tests
-- Write unit tests
-- Choose a suitable architecture to make your code simple, organizable, and maintainable
-- Using Docker to run locally
-  - Using Docker for database (if used) is mandatory.
-- Write a concise README
-  - How to run your code locally?
-  - A sample “curl” command to call your API
-  - How to run your unit tests locally?
-  - What do you love about your solution?
-  - What else do you want us to know about however you do not have enough time to complete?
-
-### Notes
-
-- We're using Golang at Manabie. **However**, we encourage you to use the programming language that you are most comfortable with because we want you to **shine** with all your skills and knowledge.
-
-### How to submit your solution?
-
-- Fork this repo and show us your development progress via a PR
-
-### Interesting facts about Manabie
-
-- Monthly there are about 2 million lines of code changes (inserted/updated/deleted) committed into our GitHub repositories. To avoid **regression bugs**, we write different kinds of **automated tests** (unit/integration (functionality)/end2end) as parts of the definition of done of our assigned tasks.
-- We nurture the cultural values: **knowledge sharing** and **good communication**, therefore good written documents and readable, organizable, and maintainable code are in our blood when we build any features to grow our products.
-- We have **collaborative** culture at Manabie. Feel free to ask trieu@manabie.com any questions. We are very happy to answer all of them.

-Thank you for spending time to read and attempt our take-home assessment. We are looking forward to your submission.
+### Run Project.
+Use docker run command:
+- `docker-compose up`
+
+### Run Test 
+- Step 1: `cd /test`
+- Step 2: Run command `go test -v`
+### List Api:
+#### Call curl below or import file postman in package document.
+- auth/register: register account.
+  ``
+  curl --location --request POST 'localhost:9000/auth/register' \
+  --header 'Content-Type: application/json' \
+  --data-raw '{
+  "userName": "admin",
+  "passWord": "123456"
+  }'
+  ``
+- auth/login: login
+  ``
+  curl --location --request POST 'localhost:9000/auth/login' \
+  --header 'Content-Type: application/json' \
+  --data-raw '{
+  "userName": "admin",
+  "passWord": "123456"
+  }'
+  ``
+- task/create: create task.
+  ``
+  curl --location --request POST 'localhost:9000/task/create' \
+  --header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2ODcwMjAwMDEsImlzcyI6Im1hbmliaWUtdG9kbyIsIklkIjoyfQ.VYSoGawZE_6XrXRfurkswKYo1x1doAAmFDpuplrUFcU' \
+  --header 'Content-Type: application/json' \
+  --data-raw '{
+  "content": "Task test danh 4"
+  }'
+  ``
+- task/list: get task by created date.
+  ``
+  curl --location --request GET 'localhost:9000/task/list?createdDate=2023-04-18' \
+  --header 'Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJleHAiOjE2ODcwMjAwMDEsImlzcyI6Im1hbmliaWUtdG9kbyIsIklkIjoyfQ.VYSoGawZE_6XrXRfurkswKYo1x1doAAmFDpuplrUFcU'
+  ``
+
+### Solution
+Limit the user to add work by day if the limit is reached then use redis cache to
+reduce the load on the database, cache on redis with userId and expire at the end of the day.
+
+### Technology used
+- Golang version 1.19
+- Postgres
+- Redis
+- Gin, Gorm
+- Docker
+- testcontainer
