-Load the database using locally persisted state. Can specify how many entries to load with `amount` argument.
+<!-- tocstop -->
 
-##### `saveSnapshot()`
+## API
 
-Save the current state of the database locally. Returns a *Promise* that resolves to a IPFS Multihash as a Base58 encoded string. The the database can be loaded using this hash.
+### constructor(ipfs, identity, address, options)
 
-##### `loadFromSnapshot(hash, onProgressCallback)`
+**ipfs** can be an [IPFS](https://github.com/ipfs/js-ipfs) instance or an [IPFS-API](https://github.com/ipfs/js-ipfs) instance. **identity** is an instance of [Identity](https://github.com/orbitdb/orbit-db-identity-provider/). **address** is the OrbitDB address to be used for the store.
 
-Load the state of the database from a snapshot. *hash* is the IPFS Multihash of the snapshot data. Returns a *Promise* that resolves when the database has been loaded.
+`options` is an object with the following required properties:
 
-##### `close()`
+- `cache`: A [Cache](https://github.com/orbitdb/orbit-db-cache) instance to use for storing heads and snapshots.
+- `Index` : By default it uses an instance of [Index](https://github.com/orbitdb/orbit-db-store/blob/master/src/Index.js).
 
-Uninitialize the store. Emits `close` after the store has been uninitialized.
+the following properties are optional:
 
-##### `drop()`
+- `maxHistory` (Integer): The number of entries to load (Default: `-1`).
+- `referenceCount` (Integer): The number of previous ipfs-log entries a new entry should reference (Default: `64`).
+- `replicationConcurrency` (Integer): The number of concurrent replication processes (Default: `128`).
+- `accessController` (Object): An instance of AccessController with the following [interface](https://github.com/orbitdb/orbit-db-access-controllers/blob/master/src/access-controller-interface.js). See [orbit-db-access-controllers](https://github.com/orbitdb/orbit-db-access-controllers) for more information on how to create custom access controllers. By default only the owner will have write access.
+- `onClose` (Function): A function to be called with a string of the OrbitDB address of the database that is closing.
 
-Remove the database locally. This doesn't remove or delete the database from peers who have replicated the database.
+### Public methods
 
-##### `sync(heads)`
+#### load([amount])
+> Load the database using locally persisted state.
 
-Sync this database with entries from *heads* where *heads* is an array of ipfs-log Entries. Usually, you don't need to call this method manually as OrbitDB takes care of this for you.
+Returns a **Promise** that resolves once complete. Provide an `amount` argument to specify how many entries to load.

+#### saveSnapshot()
+> Save the current state of the database locally.
+
+Returns a **Promise** that resolves to an array containing an object with the following properties:

+- `path` of the snapshot file
+- `hash` representing the IPFS Multihash (as a Base58 encoded string) of the snapshot file
+- `size` of the snapshot file
+
+#### loadFromSnapshot()
+> Load the state of the database from a snapshot.
+
+Returns a **Promise** that resolves to a store instance once it has been loaded.
+
+#### close()
+> Uninitialize the store.
+
+Returns a **promise** that resolves once complete. Emits `close` after the store has been uninitialized.
 
-Get the address of this database. Returns an object `{ root: <manifestHash>, path: <path> }`. Convert to a string with `db.address.toString()`.
