+# Wax packages
+
+This Wax subdirectory is responsible for maintaining Wax "extensions", e.g. signers using the pnpm's workspaces strategy
+
+## Building
+
+1. Install dependencies using `pnpm install` - this will automatically install dependencies for all of the package directories from this directory.
+2. Build all the packages using `pnpm run build`
+3. Now you can either pack: `pnpm run pack` or publish: `pnpm run publish`. Note: All of the packages will be saved under [`dist`](./dist) directory

+# @hiveio/wax-signers-keychain
+
+Wax signer library extending transaction signing possibilities by a 3rd party Web-only extension - Keychain
+
+## Prerequisites
+
+- Configured [@hiveio/wax](https://www.npmjs.com/package/@hiveio/wax) library. Wax Keychain signer is an extension the base Wax library, extending its signing possibilities by using 3rd party wallet
+- Configured [Keychain browser extension](https://hive-keychain.com/) with imported keys
+
+## Example usage
+
+```ts
+import { createHiveChain } from "@hiveio/wax";
+import KeychainProvider from "@hiveio/wax-signers-keychain";
+
+const chain = await createHiveChain();
+
+const provider = KeychainProvider.for("myaccount", "active");
+
+// Create a transaction using the Wax Hive chain instance
+const tx = await chain.createTransaction();
+
+// Perform some operations, e.g. push the vote operation:
+tx.pushOperation({
+  vote: {
+    voter: "alice",
+    author: "bob",
+    permlink: "example-post",
+    weight: 10000
+  }
+});
+
+// Wait for the keychain to sign the transaction
+await tx.sign(provider);
+
+// broadcast the transaction
+await chain.broadcast(tx);
+```
