 This api give Greenstand the ability to `like` anything, for example: like a tree, like a grower.
 
+# Development toolkit
 
------
+This repository was created from Greenstand's template for microservice projects. This means it comes with many development tools that we use for development and deployment. As a contributor to this repository, you should learn and use these tools. They are outlined below.

+# Getting Started
 
-✨ **This workspace has been generated by [Nx, a Smart, fast and extensible build system.](https://nx.dev)** ✨
+## Project Setup
 
 
-## Start the app
 
-To start the development server run `nx serve api-gateway`. Open your browser and navigate to http://localhost:4200/. Happy coding!
+Please join our slack channel to get help with setting up the database.
 
+# Workflow with Github
 
-## Generate code
+[check out here](https://github.com/Greenstand/treetracker-web-map-client#workflow-with-github)
 
-If you happen to use Nx plugins, you can leverage code generators that might come with it.
+# Development Specification
 
-Run `nx list` to get a list of available plugins and whether they have generators. Then run `nx list <plugin-name>` to see what generators are available.
+- Every endpoint should have a e2e test to cover the main use cases.
 
-Learn more about [Nx generators on the docs](https://nx.dev/plugin-features/use-code-generators).
+- For edge cases, we can use unit tests to test the edge cases, don't need to use e2e test to cover all cases, e2e just cover main workflow.
 
-## Running tasks
+- Class name should be capitalized.
 
-To execute tasks with Nx use the following syntax:
+- Do not write SQL directly in `router` and `model` files, there is a function called `delegateRepository` can help to simplify some simple cases;
+
+- Please use `loglevel` to replace `console.log`, and always use appropriate log level to log.

+# Architecture of this project
+
+
+# About the documentation/specification
+
+We use OpenAPI 3.0 to document the API.
+
+You can copy the yaml file and import to swagger-ui to see the API.
+
+# How to test
+
+## Unit test
+
+To run the unit tests:
 
 ```
-nx <target> <project> <...options>
+npm run test-unit
 ```
 
-You can also run multiple targets:
+## End to End test
+
+All the end to end tests are located under folder `__tests__/e2e`, the test will run against the dev database.
+
+To run the integration test:
+
+Run tests:
 
 ```
-nx run-many -t <target1> <target2>
+npm run test-e2e
 ```
 
-..or add `-p` to filter specific projects
+**If errors:**
 
-```
-nx run-many -t <target1> <target2> -p <proj1> <proj2>
 ```
 
-Targets can be defined in the `package.json` or `projects.json`. Learn more [in the docs](https://nx.dev/core-features/run-tasks).
+DATABASE_URL is undefined
 
-## Want better Editor Integration?
+or
 
-Have a look at the [Nx Console extensions](https://nx.dev/nx-console). It provides autocomplete support, a UI for exploring and running tasks & generators, and more! Available for VSCode, IntelliJ and comes with a LSP for Vim users.

+```
 
-## Ready to deploy?
+**Follows those steps:**
 
-Just run `nx build demoapp` to build the application. The build artifacts will be stored in the `dist/` directory, ready to be deployed.
+1- Go to the .env file, copy the DATABASE_URL with its value.
 
-## Set up CI!
+2- Add it with NODE_TLS_REJECT_UNAUTHORIZED='0' , npm run test-e2e, and run the tests.
 
-Nx comes with local caching already built-in (check your `nx.json`). On CI you might want to go a step further.
+For example:
 
-- [Set up remote caching](https://nx.dev/core-features/share-your-cache)
-- [Set up task distribution across multiple machines](https://nx.dev/core-features/distribute-task-execution)
-- [Learn more how to setup CI](https://nx.dev/recipes/ci)
