 # @dfinity/didc
 
 A multi-purpose Candid tool for JavaScript projects, including encoding and decoding Candid values. 
-
-## Usage
-
-```javascript
-import { getServiceMethods, encode, decode } from "@dfinity/didc";
-
-// The IDL in text format to be used, most canisters expose their IDL through
-// the `candid:service` public metadata.
-//
-// You can fetch the IDL with an agent call or dfx with `dfx canister metadata <canisterId> candid:service`
-export const IDL = `
-  type StoreNumberInput = record {
-    number : nat64;
-  };
-
-  service : {
-    store_number : (input : StoreNumberInput) -> ();
-    get_number : () -> (nat64) query;
-  };
-`;
-
-// Gets the service methods from the IDL and returns an array of the methods.
-//
-// Example returned value: ['store_number', 'get_number']
-const methods = getServiceMethods(IDL);
-
-// Encodes a candid text representation of a value to a hex representation.
-//
-// Example returned value: '4449444c016c01c98dea8b0a7801005a00000000000000'
-const encoded encode({
-  idl: IDL,
-  input: "(record { number=90; })",
-  serviceMethod: "store_number",
-  targetFormat: "hex",
-});
-
-// Decodes a hex representation of a candid value to a text representation.
-//
-// Example returned value: '(90 : nat64)'
-const decoded = decode({
-  idl: IDL,
-  input: "4449444c0001785a00000000000000",
-  serviceMethod: "get_number",
-  inputFormat: "hex",
-  targetFormat: "candid",
-});
-```
-
-### Web Usage
-
-For web usage, you need to initialize the async wasm module before using the functions.
-
-```javascript
-import init, { encode } from "@dfinity/didc";
-
-await init();
-
-// then you can use the functions because the wasm will be initialized
-const encoded = encode({
-  idl: IDL,
-  input: "(record { number=90; })",
-  serviceMethod: "store_number",
-  targetFormat: "hex",
-});
-```
