-## Quick Start
-
-::::steps
-
-### Determine the signing mode
-
-Currently, the Sign Protocol supports 2 modes:
-
-- OnChain:
-- OffChain:
-
-```ts twoslash
-import { SpMode } from "@ethsign/sp-sdk";
-
-// @noErrors
-SpMode. // [!code focus]
-//     ^|
-```
-
-### Setup your client
-
-Firstly, set up your Client with a desired Chain.
-
-```ts twoslash
-import { SignProtocolClient, SpMode, EvmChains } from "@ethsign/sp-sdk";
-import { privateKeyToAccount } from "viem/accounts";
-
-const privateKey = "0xabc"; // [!code focus]
-const account = privateKeyToAccount(privateKey); // [!code focus]
-
-const client = new SignProtocolClient(SpMode.OnChain, { // [!code focus]
-  chain: EvmChains.zetachainAthensTestnet, // [!code focus]
-  account, // [!code focus]
-}); // [!code focus]
-```
-
-### Create Scheme
-
-```ts twoslash
-import { SignProtocolClient, SpMode, EvmChains } from "@ethsign/sp-sdk";
-import { privateKeyToAccount } from "viem/accounts";
-
-const privateKey = "0xabc";
-const account = privateKeyToAccount(privateKey);
-
-const client = new SignProtocolClient(SpMode.OnChain, {
-  chain: EvmChains.zetachainAthensTestnet,
-  account,
-});
-
-// ---cut---
-const schema = client
-  .createSchema({
-    name: "xxx",
-    data: [{ name: "name", type: "string" }],
-  })
-  .then((result) => {
-    console.log(result);
-  });
-```
-
-### Create attestation
-
-```ts twoslash
-import { SignProtocolClient, SpMode, EvmChains } from "@ethsign/sp-sdk";
-import { privateKeyToAccount } from "viem/accounts";
-
-const privateKey = "0xabc";
-const account = privateKeyToAccount(privateKey);
-
-const client = new SignProtocolClient(SpMode.OnChain, {
-  chain: EvmChains.zetachainAthensTestnet,
-  account,
-});
-
-const schema = await client
-  .createSchema({
-    name: "xxx",
-    data: [{ name: "name", type: "string" }],
-  })
-
-const attestation = await client.createAttestation({
-  schemaId: schema.schemaId,
-  data: { name: 'a' },
-  indexingValue: 'xxx',
-})
-```
-
-### Revoke attestation
-
-```ts twoslash
-import { SignProtocolClient, SpMode, EvmChains } from "@ethsign/sp-sdk";
-import { privateKeyToAccount } from "viem/accounts";
-
-const privateKey = "0xabc";
-const account = privateKeyToAccount(privateKey);
-
-const client = new SignProtocolClient(SpMode.OnChain, {
-  chain: EvmChains.zetachainAthensTestnet,
-  account,
-});
-
-const schema = await client
-  .createSchema({
-    name: "xxx",
-    data: [{ name: "name", type: "string" }],
-  })
-
-const attestation = await client.createAttestation({
-  schemaId: schema.schemaId,
-  data: { name: 'a' },
-  indexingValue: 'xxx',
-})
-
-// ---cut---
-client.revokeAttestation(attestation.attestationId)
-```
