+# Welcome!
+
+This document is for people who want to contribute to this repository!
+
+## Code Style
+
+We use [standard.js](https://standardjs.org) with [eslint](https://eslint.org) and [typescript-eslint](https://github.com/typescript-eslint/typescript-eslint).
+So please don't make as lint errors as possible. There're many rules in standard.js but the highlight things are:
+
+- Use `camelCase` for function names, variables, etc.
+- Use `PascalCase` for class names.
+- Add return types on function. Ex:
+
+```ts
+const example = (): void => {}
+```
+
+- Do not make unused variables or unused imports.
+
+These are not on standard.js but we want you to follow.
+
+- Make names to simple but understandable for someone whose English is not a primary language.
+
+## File Name Style
+
+Nothing much, but please make it as simple as possible, and in `camelCase`.
+
+## Submitting PR
+
+When submitting PR, please make the title as simple as possible. Ex: `[Feature improvement]: Cache can now be loaded much faster`
+Also, please make it understandable for someone whose English is not a primary language.
+
+Thanks!
