+## Getting an API key
+
+API keys are issued by Socialhose. The SDK does not create keys, and there is no self-service key-generation flow documented in this package.
+
+To use the SDK:
+
+1. Request Socialhose Public API access from the Socialhose team or your account administrator.
+2. Ask for an API key with access to the campaigns you need to query.
+3. Store it as a server-side environment variable:
+
+```bash
+export SOCIALHOSE_API_KEY="sh_your_key_here"
+```
+
+4. Pass it to the client:
+
+```ts
+const socialhose = new SocialhoseClient({
+  apiKey: process.env.SOCIALHOSE_API_KEY!,
+});
+```
+
+Do not commit API keys, expose them in frontend bundles, or send them to browsers. If you are building a web app, call Socialhose from your server/API route and return only the data your frontend needs.

+## Getting API access
+
+Socialhose API keys are provisioned by Socialhose. This SDK only consumes an existing key; it cannot create, rotate, or discover keys for you.
+
+Ask the Socialhose team or your account administrator for a Public API key and confirm which campaigns it can access. Then set it in your server environment:

+```bash
+export SOCIALHOSE_API_KEY="sh_your_key_here"

+Keep this value server-side. For browser applications, create your own backend endpoint that uses this SDK and returns sanitized data to the frontend.
