+# Stellar SEP-0005
+
+A key derivation library for Stellar following
+[SEP-0005](https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0005.md) based on the popular library
+[stellar-hd-wallet](https://github.com/chatch/stellar-hd-wallet).
+
+Why making a new library? Because the library `stellar-hd-wallet` uses Node.js features and so it is not compatible with
+some frameworks and environments if you don't use a polyfill (like Angular, Deno, Vanilla JS, etc.)
+
+# Install
+
+```shell
+# Node
+npx jsr add @creit-tech/stellar-sep-0005
+
+# Deno
+deno add jsr:@creit-tech/stellar-sep-0005
+```
+
+You can check more installation options in the [JSR package](https://jsr.io/@creit-tech/stellar-sep-0005).
+
+# How to use
+
+```typescript
+import { Keypair } from "@stellar/stellar-sdk";
+import { deriveAccount, generateMnemonic, seedFromMnemonic } from "@creit-tech/stellar-sep-0005";
+
+const mnemonic: string = generateMnemonic();
+const seed: Uint8Array = await seedFromMnemonic({ mnemonic });
+const rawEd25519Seed: Uint8Array = await deriveAccount({ seed, account: 0 });
+const keypair: Keypair = Keypair.fromRawEd25519Seed(rawEd25519Seed as any);
+```
+
+> Note: In our example we use `as any` to ignore the Typescript error saying Uint8Array is missing Buffer features, for
+> the `Keypair.fromRawEd25519Seed` case those are not used so it's safe to ignore the alert.
