+# Golem Network Plugins
+
+Welcome to the Golem Network Plugins documentation! Here we aim to provide friendly and comprehensive guidance for
+developers interested in creating reusable and generic modules for the Golem Network.
+
+## Why do we need plugins?
+
+### Requestor script maintainability
+
+As detailed in our [concepts](./CONCEPTS.md) guide, the SDK models the intricate domain of the Golem Network by defining
+the `GolemNetwork` class, which is built from various subdomains of the project.
+
+If you've written a few `golem-js` scripts, you might have noticed your scripts growing quickly as you add logic for
+market, activity, or payment events. This can make your main requestor script bulky and difficult to maintain.
+
+Golem Plugins offer a solution to this problem by providing a simple interface for attaching different types of logic to
+your `GolemNetwork` instance. This allows you to break down your large scripts into smaller, more manageable modules and
+use `GolemNetwork.use` to integrate them into your main script seamlessly.
+
+### Opening the ecosystem for extensions
+
+We warmly invite other developers to [contribute](./CONTRIBUTING.md) to our ecosystem. We recognize that creating core
+SDK components requires considerable effort and dedication.
+
+To make contributions more accessible, we're introducing a new pathway for developers familiar with `golem-js` to create
+their `GolemNetwork` plugins and share them via NPM.
+
+## Example plugins
+
+### Provider tracker
+
+Let's say you want to track unique providers on the network for statistical purposes. Here's an example plugin:
+
+```ts
+import { GolemNetwork, GolemPluginInitializer } from "@golem-sdk/golem-js";
+
+/**
+ * Example plugin that tracks unique provider ID/name pairs on the market
+ */
+const providerTracker: GolemPluginInitializer = (glm) => {
+  const seenProviders: { id: string; name: string }[] = [];
+
+  glm.market.events.on("offerProposalReceived", (event) => {
+    const { id, name } = event.offerProposal.provider;
+    const providerInfo = { id, name };
+    if (!seenProviders.includes(providerInfo)) {
+      seenProviders.push(providerInfo);
+      console.log("Saw new provider %s named %s", id, name);
+    }
+  });
+
+  // Return a cleanup function that will be executed during the `disconnect`
+  return () => {
+    console.log("Provider tracker found a total of %d providers", seenProviders.length);
+  };
+};
+```
+
+You can connect this plugin to your main script as follows:
+
+```ts
+const glm = new GolemNetwork();
+
+// Register the plugin that will be initialized during `connect` call
+glm.use(providerTracker);
+```
+
+#### Check GLM price before starting (asynchronous plugin)
+
+If you want to avoid running your requestor script when the GLM price exceeds a certain USD value, you can capture this
+policy with a reusable plugin:
+
+```ts
+import { GolemNetwork, GolemPluginInitializer } from "@golem-sdk/golem-js";
+
+const checkGlmPriceBeforeStarting: GolemPluginInitializer<{
+  maxPrice: number;
+}> = async (_glm, opts) => {
+  // Call an exchange to get the quotes
+  const response = await fetch("https://api.coinpaprika.com/v1/tickers/glm-golem");
+
+  if (!response.ok) {
+    throw new Error("Failed to fetch GLM price");
+  } else {
+    // Execute your logic
+    const data = await response.json();
+    const price = parseFloat(data.quotes.USD.price);
+
+    console.log("=== GLM Price ===");
+    console.log("GLM price is", price);
+    console.log("=== GLM Price ===");
+
+    if (price > opts.maxPrice) {
+      // Throwing inside the plugin will make `connect` throw, and then prevent
+      // execution of the rest of the script
+      throw new Error("GLM price is too high, won't compute today :O");
+    }
+  }
+};
+```
+
+Here's how to use the plugin:
+
+```ts
+const glm = new GolemNetwork();
+
+glm.use(checkGlmPriceBeforeStarting, {
+  maxPrice: 0.5,
+});
+```
+
+## Plugin lifecycle and cleanup
+
+When you register plugins using `GolemNetwork.use`, they are initialized during the `GolemNetwork.connect` call. If any
+plugin throws an error during initialization, the entire `connect` method will throw an error.
+
+Each plugin can return a cleanup function, which will be executed during `GolemNetwork.disconnect`. This is particularly
+useful for plugins that allocate resources, use timers, or open database connections.
+
+## Synchronous and asynchronous plugins
+
+The SDK supports both synchronous and asynchronous plugins. You can register all of them using the `GolemNetwork.use`
+method, and they will be initialized sequentially in the order they were registered.
