 # PDODocument
 
-This library allows SQLite (and, by v1.0.0-beta1, PostgreSQL) to be treated as a document database. It is a PHP implementation of the .NET [BitBadger.Documents](https://git.bitbadger.solutions/bit-badger/BitBadger.Documents) library.
+This library allows SQLite and PostgreSQL to be treated as document databases. It is a PHP implementation of the .NET [BitBadger.Documents](https://git.bitbadger.solutions/bit-badger/BitBadger.Documents) library.
 
 ## Add via Composer
 
-`compose require bit-badger/pdo-document`
+[![Packagist Version](https://img.shields.io/packagist/v/bit-badger/pdo-document)](https://packagist.org/packages/bit-badger/pdo-document)
+
+`composer require bit-badger/pdo-document`
+
+## Configuration
+
+### Connection Details
+
+The [PDO data source name](https://www.php.net/manual/en/pdo.construct.php#refsect1-pdo.construct-parameters) must be provided via `Configuration::useDSN()`. `Configuration` also has `$username`, `$password`, and `$options` variables that will be used to construct the PDO object it will use for data access.
+
+### Document Identifiers
+
+Each document must have a unique identifier. By default, the library assumes that this is a property or array key named `id`, but this can be controlled by setting `Configuration::$idField`. Once documents exist, this should not be changed.
+
+IDs can be generated automatically on insert. The `AutoId` enumeration has 4 values:
+
+- `AutoId::None` is the default; no IDs will be generated
+- `AutoId::Number` will assign max-ID-plus-one to documents with an ID of 0
+- `AutoId::UUID` will generate a v4 <abbr title="Universally Unique Identifier">UUID</abbr> for documents with an empty `string` ID
+- `AutoId::RandomString` will generate a string of letters and numbers for documents with an empty `string` ID; `Configuration::$idStringLength` controls the length of the generated string, and defaults to 16 characters
+
+In all generated scenarios, if the ID value is not 0 or blank, that ID will be used instead of a generated one.
 
 ## Usage
 
-Documentation for this library is not complete; however, its structure is very similar to the .NET version, so [its documentation will help](https://bitbadger.solutions/open-source/relational-documents/basic-usage.html) until its project specific documentation is developed. Things like `Count.All()` become `Count::all`, and all the `byField` operations are named `byFields` and take an array of fields.
+Full documentation [is available on the project site](https://bitbadger.solutions/open-source/pdo-document/).
