 Alex-SDK is a easy-to-use library that exposes the swap functionality from [alexlab.co](https://app.alexlab.co/swap) to be integrated into any app or wallet. It enables users to perform swaps with a wide variety of supported currencies.
 
-## Supported Currencies
-
-The SDK supports the following currencies:
-
-```typescript
-export enum Currency {
-  ALEX = 'age000-governance-token',
-  USDA = 'token-wusda',
-  STX = 'token-wstx',
-  BANANA = 'token-wban',
-  XBTC = 'token-wbtc',
-  DIKO = 'token-wdiko',
-  SLIME = 'token-wslm',
-  XUSD = 'token-wxusd',
-  MIA = 'token-wmia',
-  NYCC = 'token-wnycc',
-  CORGI = 'token-wcorgi',
-}
-```
-
-## Functions
-
-The AlexSDK class includes the following functions:
-
-```typescript
-export declare class AlexSDK {
-    getFeeRate(from: Currency, to: Currency): Promise<bigint>;
-    getRouter(from: Currency, to: Currency): Promise<Currency[]>;
-    getAmountTo(from: Currency, fromAmount: bigint, to: Currency): Promise<bigint>;
-    runSwap(stxAddress: string, currencyX: Currency, 
-            currencyY: Currency, fromAmount: bigint, 
-            minDy: bigint, router: Currency[]): Promise<TxToBroadCast>;
-    getLatestPrices(): Promise<Partial<{ [currency in Currency]: number }>>;
-    getBalances(stxAddress: string): Promise<Partial<{ [currency in Currency]: bigint }>>;
-    fetchSwappableCurrency(): Promise<TokenInfo[]>;
-}
-```
-
-### getFee
-Rate
-Get the swap fee (liquidity provider fee) between two currencies.
-
-```typescript
-async function getFeeRate(from: Currency, to: Currency): Promise<bigint>;
-```
-
-Possible exceptions: `Failed to fetch token mappings`, `No AMM pools in route`, `Too many AMM pools in route`, `Error calling read-only function`.
-
-### getRouter
-
-Get the router path for swapping between two currencies.
-
-```typescript
-async function getRouter(from: Currency, to: Currency): Promise<Currency[]>;
-```
-
-Possible exceptions: `Failed to fetch token mappings`, `Can't find route`.
-
-### getAmountTo
-
-Get the amount of destination currency that will be received when swapping from one currency to another.
-
-```typescript
-async function getAmountTo(from: Currency, fromAmount: bigint, to: Currency): Promise<bigint>;
-```
-
-Possible exceptions: `Failed to fetch token mappings`, `No AMM pool found for the given route`, `Too many AMM pools in route`, `Error calling read-only function`.
-
-
-### runSwap
-
-Perform a swap between two currencies using the specified route and amount.
-
-```typescript
-function runSwap(stxAddress: string, currencyX: Currency, currencyY: Currency, 
-                  fromAmount: bigint, minDy: bigint, router: Currency[]): Promise<TxToBroadCast>;
-```
-
-Possible exceptions: `Failed to fetch token mappings`, `Can't find AMM route`, `Token mapping not found`, `Too many AMM pools in route`.
-
-### getLatestPrices
-
-This function fetches the current price data for all supported tokens. It returns an object where the keys are the currency identifiers (as defined in the `Currency` enum) and the values are the corresponding prices in USD.
-
-```typescript
-async function getLatestPrices(): Promise<Partial<{ [currency in Currency]: number }>>;
-```
-Possible exceptions: `Failed to fetch token mappings`.
-
-### getBalances
-
-This function fetches the current balances of all supported tokens for a specified STX address. It returns an object where the keys are the currency identifiers (as defined in the `Currency` enum) and the values are the corresponding balances as `bigint` values.
-
-```typescript
-async function getBalances(stxAddress: string): Promise<Partial<{ [currency in Currency]: bigint }>>;
-```
-
-Possible exceptions: `Failed to fetch token mappings`.
-
-
-### fetchSwappableCurrency
-
-This function returns an array of `TokenInfo` objects, each containing detailed information about a supported swappable currency.
-
-```typescript
-function fetchSwappableCurrency(): Promise<TokenInfo[]>;
-```
-
-Possible exceptions: `Failed to fetch token mappings`.
