+
+This is a small wrapper around SQLite for the D programming language.
+It wraps the C API in an idiomatic manner and handles built-in D types and
+`Nullable!T` automatically.

+## Documentation

+
+## `dub` configurations
+
+- **`with-lib`** (the default): assumes that SQLite is already installed and available to the linker. Set the right path for the SQLite library in your project's `dub.json` file using the `lflags` setting:
+
+```json
+    "lflags": ["-L/path/to/lib"]
+```
+
+- **`without-lib`**: you manage linking SQLite yourself.
+
+- **`all-included`**: on Windows, use a prebuilt SQLite DLL (bundled with this library); on Posix systems, builds SQLite from the source amalgamation (bundled with this library), using the default building configuration with these options defined:
+  - SQLITE_ENABLE_COLUMN_METADATA
+  - SQLITE_ENABLE_UNLOCK_NOTIFY
+
+Set the right configuration for you project in its `dub.json` file using the `subConfigurations` setting, e.g.:
+
+```json
+    "subConfigurations": {
+        "d2sqlite3": "all-included"
+    }
+```
+
+## Library versions
+
+These versions can be used to build the library:
+
+- `SqliteEnableColumnMetadata`: to enable corresponding special methods of `Row`.
+- `SqliteEnableUnlockNotify`: to enable SQLite's builtin unlock notification mechanism.
+- `SqliteFakeUnlockNotify`: to emulate an unlock notification mechanism.
+
+## C binding generation
+
+The D binding file `sqlite3.d` is generated from the C header file `sqlite3.h`, using [jacob-carlborg/dstep](https://github.com/jacob-carlborg/dstep). I try to keep it up to date.
