+# grants-stack-indexer: repository package
+
+This package provides a data access layer for the grants-stack-indexer project, implementing the Repository pattern to abstract database operations.
+
+## Setup
+
+1. Install dependencies by running `pnpm install` in the root directory of the project.
+
+## Available Scripts
+
+Available scripts that can be run using `pnpm`:
+

+
+## Usage
+
+This package provides repository interfaces and implementations for projects and rounds. It uses Kysely as the query builder library.
+
+### Creating a database connection
+
+```typescript
+import { createKyselyPostgresDb, DatabaseConfig } from "@grants-stack-indexer/repository";
+
+const dbConfig: DatabaseConfig = {
+    connectionString: "postgresql://user:password@localhost:5432/mydb",
+};
+
+const db = createKyselyPostgresDb(dbConfig);
+
+// Instantiate a repository
+const projectRepository = new KyselyProjectRepository(db, "mySchema");
+
+const projects = await projectRepository.getProjects(10);
+```
+
+## API
+
+### Repositories
+
+This package provides the following repositories:
+
+1. **IProjectRepository**: Manages project-related database operations, including project roles and pending roles.
+
+2. **IRoundRepository**: Manages round-related database operations, including round roles and pending roles.
