 A lightweight wallet implementation. At the moment it supports key creation and conversion between various formats.
 
 It is complemented by the following packages:
+
 - [ethereumjs-tx](https://github.com/ethereumjs/ethereumjs-tx) to sign transactions
 - [ethereumjs-icap](https://github.com/ethereumjs/ethereumjs-icap) to manipulate ICAP addresses
 - [store.js](https://github.com/marcuswestin/store.js) to use browser storage
 
 Motivations are:
+
 - be lightweight
 - work in a browser
 - use a single, maintained version of crypto library (and that should be in line with `ethereumjs-util` and `ethereumjs-tx`)
 - support import/export between various wallet formats
 - support BIP32 HD keys
 
 Features not supported:
+
 - signing transactions
 - managing storage (neither in node.js or the browser)
 
 ## Wallet API
 
 Constructors:
 
-* `generate([icap])` - create an instance based on a new random key (setting `icap` to true will generate an address suitable for the `ICAP Direct mode`)
-* `generateVanityAddress(pattern)` - create an instance where the address is valid against the supplied pattern (**this will be very slow**)
-* `fromPrivateKey(input)` - create an instance based on a raw private key
-* `fromExtendedPrivateKey(input)` - create an instance based on a BIP32 extended private key (xprv)
-* `fromPublicKey(input, [nonStrict])` - create an instance based on a public key (certain methods will not be available)
-* `fromExtendedPublicKey(input)` - create an instance based on a BIP32 extended public key (xpub)
-* `fromV1(input, password)` - import a wallet (Version 1 of the Ethereum wallet format)
-* `fromV3(input, password, [nonStrict])` - import a wallet (Version 3 of the Ethereum wallet format). Set `nonStrict` true to accept files with mixed-caps.
-* `fromEthSale(input, password)` - import an Ethereum Pre Sale wallet

+- `fromEthSale(input, password)` - import an Ethereum Pre Sale wallet
 
 For the V1, V3 and EthSale formats the input is a JSON serialized string. All these formats require a password.
 
 Note: `fromPublicKey()` only accepts uncompressed Ethereum-style public keys, unless the `nonStrict` flag is set to true.
 
 Instance methods:
 
-* `getPrivateKey()` - return the private key
-* `getPublicKey()` - return the public key
-* `getAddress()` - return the address
-* `getChecksumAddressString()` - return the [address with checksum](https://github.com/ethereum/EIPs/issues/55)
-* `getV3Filename([timestamp])` - return the suggested filename for V3 keystores
-* `toV3(password, [options])` - return the wallet as a JSON string (Version 3 of the Ethereum wallet format)

 All of the above instance methods return a Buffer or JSON. Use the `String` suffixed versions for a string output, such as `getPrivateKeyString()`.

 The `options` is an optional object hash, where all the serialization parameters can be fine tuned:
+
 - uuid - UUID. One is randomly generated.
 - salt - Random salt for the `kdf`. Size must match the requirements of the KDF (key derivation function). Random number generated via `crypto.getRandomBytes` if nothing is supplied.
 - iv - Initialization vector for the `cipher`. Size must match the requirements of the cipher. Random number generated via `crypto.getRandomBytes` if nothing is supplied.

 Depending on the `kdf` selected, the following options are available too.
 
 For `pbkdf2`:
+
 - `c` - Number of iterations. Defaults to 262144.
 - `prf` - The only supported (and default) value is `hmac-sha256`. So no point changing it.
 
 For `scrypt`:
+
 - `n` - Iteration count. Defaults to 262144.
 - `r` - Block size for the underlying hash. Defaults to 8.
 - `p` - Parallelization factor. Defaults to 1.
 
 The following settings are favoured by the Go Ethereum implementation and we default to the same:
+
 - `kdf`: `scrypt`
 - `dklen`: `32`
 - `n`: `262144`
