+## Inserting One Document
+
+The [insertOne()][insertone] method may be used to insert a single document.
+This method returns an instance of `MongoDB\InsertOneResult`, which may be used
+to access the ID of the inserted document. Note that if a document does not
+contain an `_id` field at the time of insertion, the driver will generate a
+`MongoDB\BSON\ObjectID` to use as its ID.
+
+[insertone]: ../classes/collection.md#insertone
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$insertOneResult = $collection->insertOne(['name' => 'Bob']);
+
+printf("Inserted %d document(s)\n", $insertOneResult->getInsertedCount());
+var_dump($insertOneResult->getInsertedId());
+```
+
+The above example would output something similar to:
+
+```
+Inserted 1 document(s)
+object(MongoDB\BSON\ObjectID)#10 (1) {
+  ["oid"]=>
+  string(24) "5750905b6118fd170565aa81"
+}
+```
+
+The following example inserts a document with an ID. Note that if an ID is not
+unique for the collection, the insert will fail due to a duplicate key error.
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$insertOneResult = $collection->insertOne(['_id' => 1, 'name' => 'Alice']);
+
+printf("Inserted %d document(s)\n", $insertOneResult->getInsertedCount());
+var_dump($insertOneResult->getInsertedId());
+```
+
+The above example would output:
+
+```
+Inserted 1 document(s)
+int(1)
+```
+
+## Inserting Many Documents
+
+The [insertMany()][insertmany] method may be used to insert multiple documents
+at a time. This method returns an instance of `MongoDB\InsertManyResult`, which
+may be used to access the IDs of the inserted documents.
+
+[insertmany]: ../classes/collection.md#insertmany
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$insertManyResult = $collection->insertMany([
+    ['name' => 'Bob'],
+    ['_id' => 1, 'name' => 'Alice'],
+]);
+
+printf("Inserted %d document(s)\n", $insertManyResult->getInsertedCount());
+var_dump($insertManyResult->getInsertedIds());

+
+The above example would output something similar to:

+
+## Updating One Document
+
+The [updateOne()][updateone] method may be used to update a single document
+matching a filter. This method returns an instance of `MongoDB\UpdateResult`,
+which may be used to access statistics about the update operation.
+
+[updateone]: ../classes/collection.md#updateone
+
+This method has two required parameters: a query filter and an update document.
+The query filter is similar to what might be provided to [find()][find]. The
+update document consists of one or more [update operators][updateops].
+
+[updateops]: https://docs.mongodb.com/manual/reference/operator/update/
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
+$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
+$updateResult = $collection->updateOne(
+    ['state' => 'ny'],
+    ['$set' => ['country' => 'us']]
+);
+
+printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
+printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
+```
+
+The above example would output something similar to:
+
+```
+Matched 1 document(s)
+Modified 1 document(s)
+```
+
+Note that it is possible for a document to match the filter but not be modified
+by an update:
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
+$updateResult = $collection->updateOne(
+    ['name' => 'Bob'],
+    ['$set' => ['state' => 'ny']]
+);
+
+printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
+printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
+```
+
+The above example would output something similar to:
+
+```
+Matched 1 document(s)
+Modified 0 document(s)
+```
+
+## Updating Many Documents
+
+The [updateMany()][updatemany] method may be used to update multiple documents
+at a time. This method returns an instance of `MongoDB\UpdateResult`, which may
+be used to access statistics about the update operation.
+
+[updatemany]: ../classes/collection.md#updatemany
+
+This method has two required parameters: a query filter and an update document.
+The query filter is similar to what might be provided to [find()][find]. The
+update document consists of one or more [update operators][updateops].
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$collection->insertOne(['name' => 'Bob', 'state' => 'ny', 'country' => 'us']);
+$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
+$collection->insertOne(['name' => 'Sam', 'state' => 'ny']);
+$updateResult = $collection->updateMany(
+    ['state' => 'ny'],
+    ['$set' => ['country' => 'us']]
+);
+
+printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
+printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
+```
+
+The above example would output something similar to:
+
+```
+Matched 3 document(s)
+Modified 2 document(s)
+```
+
+## Replacing a Document
+
+The [replaceOne()][replaceone] method may be used to replace a single document
+matching a filter. This method returns an instance of `MongoDB\UpdateResult`,
+which may be used to access statistics about the replacement operation.
+
+[replaceone]: ../classes/collection.md#replaceone
+
+This method has two required parameters: a query filter and a replacement
+document. The query filter is similar to what might be provided to
+[find()][find]. The replacement document will be used to overwrite the matched
+document (excluding its ID, which is immutable) and must not contain
+[update operators][updateops].
+
+Note that the very nature of a replacement operation makes it easy to
+inadvertently overwrite or delete fields in a document. When possible, users
+should consider updating individual fields with [updateOne()][updateone] or
+[updateMany()][updatemany].
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
+$updateResult = $collection->replaceOne(
+    ['name' => 'Bob'],
+    ['name' => 'Robert', 'state' => 'ca']
+);
+
+printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
+printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
+```
+
+The above example would output something similar to:
+
+```
+Matched 1 document(s)
+Modified 1 document(s)
+```
+
+Note that it is possible for a document to match the filter but not be modified
+by a replacement (i.e. the matched document and replacement may be the same).
+
+## Upserting a Document
+
+An upsert is a variation of an update or replace operation, whereby a new
+document is inserted if the query filter does not match an existing document.
+An upsert may be specified via the `upsert` option for [updateOne()][updateone],
+[updateMany()][updatemany], or [replaceOne()][replaceone]. The logic by which
+the inserted document is created is discussed in the [MongoDB manual][upsert].
+
+[upsert]: https://docs.mongodb.com/manual/reference/method/db.collection.update/#upsert-parameter
+
+If a document has been upserted, its ID will be accessible via
+`MongoDB\UpdateResult::getUpsertedId()`.
+
+The following example demonstrates an upsert via [updateOne()][updateone]:
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$updateResult = $collection->updateOne(
+    ['name' => 'Bob'],
+    ['$set' => ['state' => 'ny']],
+    ['upsert' => true]
+);
+
+printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
+printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
+var_dump($collection->findOne(['_id' => $updateResult->getUpsertedId()]));
+```
+
+The above example would output something similar to:
+
+```
+Matched 0 document(s)
+Modified 0 document(s)
+object(MongoDB\Model\BSONDocument)#16 (1) {
+  ["storage":"ArrayObject":private]=>
+  array(3) {
+    ["_id"]=>
+    object(MongoDB\BSON\ObjectID)#15 (1) {
+      ["oid"]=>
+      string(24) "57509c4406d7241dad86e7c3"
+    }
+    ["name"]=>
+    string(3) "Bob"
+    ["state"]=>
+    string(2) "ny"
+  }
+}
+```
+
+The following example demonstrates an upsert via [replaceOne()][replaceone]:
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$updateResult = $collection->replaceOne(
+    ['name' => 'Bob'],
+    ['name' => 'Alice', 'state' => 'ny'],
+    ['upsert' => true]
+);
+
+printf("Matched %d document(s)\n", $updateResult->getMatchedCount());
+printf("Modified %d document(s)\n", $updateResult->getModifiedCount());
+var_dump($collection->findOne(['_id' => $updateResult->getUpsertedId()]));
+```
+
+The above example would output something similar to:
+
+```
+Matched 0 document(s)
+Modified 0 document(s)
+object(MongoDB\Model\BSONDocument)#16 (1) {
+  ["storage":"ArrayObject":private]=>
+  array(3) {
+    ["_id"]=>
+    object(MongoDB\BSON\ObjectID)#15 (1) {
+      ["oid"]=>
+      string(24) "57509c6606d7241dad86e7c4"
+    }
+    ["name"]=>
+    string(5) "Alice"
+    ["state"]=>
+    string(2) "ny"
+  }
+}
+```
+
+## Deleting One Document
+
+The [deleteOne()][deleteone] method may be used to delete a single document
+matching a filter. This method returns an instance of `MongoDB\DeleteResult`,
+which may be used to access statistics about the delete operation.
+
+[deleteone]: ../classes/collection.md#deleteone
+
+This method has two required parameters: a query filter. The query filter is
+similar to what might be provided to [find()][find].
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
+$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
+$deleteResult = $collection->deleteOne(['state' => 'ny']);
+
+printf("Deleted %d document(s)\n", $deleteResult->getDeletedCount());
+```
+
+The above example would output something similar to:
+
+```
+Deleted 1 document(s)
+```
+
+## Deleting Many Documents
+
+The [deleteMany()][deletemany] method may be used to delete multiple documents
+at a time. This method returns an instance of `MongoDB\DeleteResult`, which may
+be used to access statistics about the delete operation.
+
+[deletemany]: ../classes/collection.md#deletemany
+
+This method has two required parameters: a query filter. The query filter is
+similar to what might be provided to [find()][find].
+
+```
+<?php
+
+$collection = (new MongoDB\Client)->demo->users;
+$collection->drop();
+
+$collection->insertOne(['name' => 'Bob', 'state' => 'ny']);
+$collection->insertOne(['name' => 'Alice', 'state' => 'ny']);
+$deleteResult = $collection->deleteMany(['state' => 'ny']);
+
+printf("Deleted %d document(s)\n", $deleteResult->getDeletedCount());

+
+The above example would output something similar to:
+
