+# Managing Dependencies with Import Maps
+
+In the previous examples, we used direct URL imports like
+`jsr:@denops/std@^8.0.0`. While this works, the recommended approach for Denops
+plugins (v8.0.0+) is to use import maps with `deno.jsonc` for cleaner and more
+maintainable dependency management.
+
+## Why Use Import Maps?
+
+The main reason to use import maps is to avoid conflicts between multiple Denops
+plugins. Each Denops plugin must have a unique directory name under `denops/`,
+but root-level configuration files could potentially conflict:
+
+```
+# Multiple plugins installed:
+~/.vim/pack/plugins/start/plugin-a/
+├── deno.jsonc              # Could conflict
+└── denops/plugin-a/        # Always unique
+
+~/.vim/pack/plugins/start/plugin-b/
+├── deno.jsonc              # Could conflict  
+└── denops/plugin-b/        # Always unique
+```
+
+Some plugin managers have a "merge" feature that combines plugin directories,
+but even without merging, placing configuration files in plugin-specific
+directories (`denops/plugin-name/`) ensures no conflicts can occur regardless of
+how plugins are installed or managed.
+
+## Setting Up Your Plugin Structure
+
+Update your `denops-helloworld` structure to include configuration files:
+
+```
+denops-helloworld/
+├── deno.jsonc                    # Development configuration
+├── denops/
+│   └── denops-helloworld/
+│       ├── deno.jsonc           # Runtime dependencies
+│       └── main.ts
+└── plugin/
+    └── denops-helloworld.vim
+```
+
+### Root deno.jsonc (Development)
+
+Create a `deno.jsonc` in your repository root for workspace configuration:
+
+```json
+{
+  "workspace": [
+    "./denops/denops-helloworld"
+  ]
+}
+```
+
+This enables Deno commands like `deno fmt`, `deno lint`, and `deno test` to work
+from your project root and discover your plugin's configuration.
+
+### Plugin deno.jsonc (Runtime)
+
+Create `denops/denops-helloworld/deno.jsonc` for runtime dependencies:
+
+```json
+{
+  "imports": {
+    "@denops/std": "jsr:@denops/std@^8.0.0",
+    "@core/unknownutil": "jsr:@core/unknownutil@^4.3.0"
+  }
+}
+```
+
+## Updating Your Code
+
+With import maps configured, update your imports from:
+
+```typescript
+import type { Entrypoint } from "jsr:@denops/std@^8.0.0";
+import { assert, is } from "jsr:@core/unknownutil@^4.3.0";
+```
+
+To cleaner versions:
+
+```typescript
+import type { Entrypoint } from "@denops/std";
+import { assert, is } from "@core/unknownutil";
+```
+
+## Alternative: import_map.json
+
+Denops also supports `import_map.json(c)` files, but they require more verbose
+configuration due to the
+[Import Maps Standard](https://github.com/WICG/import-maps):
+
+```json
+// denops/denops-helloworld/import_map.json
+{
+  "imports": {
+    "@denops/std": "jsr:@denops/std@^8.0.0",
+    "@denops/std/": "jsr:/@denops/std@^8.0.0/" // Required for submodules
+  }
+}
+```
+
+We recommend using `deno.jsonc` as it's less verbose and integrates better with
+Deno tooling. For more details about the differences, see the
+[Deno documentation](https://docs.deno.com/runtime/fundamentals/modules/#differentiating-between-imports-or-importmap-in-deno.json-and---import-map-option).
+
+> [!IMPORTANT]
+>
+> Import map features require Denops v8.0.0 or later. For older versions,
+> continue using direct URL imports.
+
+## Benefits
+
+1. **Cleaner imports**: No more long URLs in your code
+2. **Version management**: Update dependencies in one place
+3. **Better IDE support**: Auto-completion and type checking work seamlessly
+4. **No conflicts**: Each plugin manages its own dependencies
+5. **Development tools**: Format and lint your code from the project root
