 # RONIN Compiler
 
-This package compiles RONIN queries to SQL statements.
+This package compiles [RONIN queries](https://ronin.co/docs/queries) to SQL statements.
 
-## Usage
+## Setup
 
+You don't need to install this package explicitly, as it is already included in the [RONIN client](https://github.com/ronin-co/client).
+
+However, we would be excited to welcome your feature suggestions or bug fixes for the RONIN compiler. Read on to learn more about how to suggest changes.
+
+## Contributing
+
+To start contributing code, first make sure you have [Bun](https://bun.sh) installed, which is a JavaScript runtime.
+
+Next, [clone the repo](https://docs.github.com/en/repositories/creating-and-managing-repositories/cloning-a-repository) and install its dependencies:
+
+```bash
+bun install
+```
+
+Once that's done, link the package to make it available to all of your local projects:
+
+```bash
+bun link
+```
+
+Inside your project, you can then run the following command, which is similar to `bun add @ronin/compiler` or `npm install @ronin/compiler`, except that it doesn't install `@ronin/compiler` from npm, but instead uses your local clone of the package:
+
+```bash
+bun link @ronin/compiler
+```
+
+If your project is not yet compatible with [Bun](https://bun.sh), feel free to replace all of the occurrences of the word `bun` in the commands above with `npm` instead.
+
+You will just need to make sure that, once you [create a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request#creating-the-pull-request) on the current repo, it will not contain a `package-lock.json` file, which is usually generated by npm. Instead, we're using the `bun.lockb` file for this purpose (locking sub dependencies to a certain version).
+
+### Developing
+
+The programmatic API of the RONIN compiler looks like this:
+
 ```typescript
-import { compileQueryInput } from '@ronin/compiler';
+import {
+  compileQueries,
 
-const query = {
+  type Query,
+  type Schema,
+  type Statement
+} from '@ronin/compiler';
+
+const queries: Array<Query> = [{
   get: {
-    accounts: null,
-  },
-};
+    accounts: null
+  }
+}];
 
-const schemas = [
-  {
-    pluralSlug: 'accounts',
-    slug: 'account',
-  },
-];
+const schemas: Array<Schema> = [{
+  slug: 'account'
+}];
 
-const { writeStatements, readStatement } = compileQueryInput(query, schemas);
+const statements: Array<Statements> = compileQueries(queries, schemas);
+// [{
+//   statement: 'SELECT * FROM "accounts"',
+//   params: [],
+//   returning: true,
+// }]
+```
 
-console.log(readStatement);
-// SELECT * FROM "accounts" ORDER BY "ronin.createdAt" DESC LIMIT 101
+#### Options
+
+To fine-tune the behavior of the compiler, you can pass the following options:
+
+```typescript
+compileQueries(queries, schemas, {
+  // Instead of returning an array of values for every statement (which allows for
+  // preventing SQL injections), all values are inlined directly into the SQL strings.
+  // This option should only be used if the generated SQL will be manually verified.
+  inlineValues: true
+});
 ```
 
-## Testing
+#### Transpilation
 
-Use the following command to run the test suite:
+In order to be compatible with a wide range of projects, the source code of the `compiler` repo needs to be compiled (transpiled) whenever you make changes to it. To automate this, you can keep this command running in your terminal:
 
+```bash
+bun run dev
 ```
+
+Whenever you make a change to the source code, it will then automatically be transpiled again.
+
+### Running Tests
+
+The RONIN compiler has 100% test coverage, which means that every single line of code is tested automatically, to ensure that any change to the source code doesn't cause a regression.
+
+Before you create a pull request on the `compiler` repo, it is therefore advised to run those tests in order to ensure everything works as expected:
+
+```bash
+# Run all tests
 bun test
+
+# Alternatively, run a single test
+bun test -t 'your test name'
 ```
