+# Basic Usage
+
+This guide covers the fundamental concepts and patterns for using Eliza in your applications.
+
+## Creating an Agent Runtime
+
+The first step is to initialize an agent runtime with your desired configuration:
+```
+import { AgentRuntime, SqliteDatabaseAdapter } from "eliza";
+import { Database } from "sqlite3";
+const sqliteDatabaseAdapter = new SqliteDatabaseAdapter(new Database(":memory:"));
+const runtime = new AgentRuntime({
+serverUrl: "https://api.openai.com/v1",
+token: process.env.OPENAI_API_KEY,
+databaseAdapter: sqliteDatabaseAdapter,
+model: "gpt-3.5-turbo",
+embeddingModel: "text-embedding-3-small"
+});
+```
+
+## Loading Characters
+
+Characters can be loaded from JSON files:
+```json
+{
+"name": "character_name",
+"bio": [],
+"lore": [],
+"knowledge": [],
+"style": {}
+}
+```
+
+Load the character:
+```
+node --loader ts-node/esm src/index.ts --characters="path/to/your/character.json"
+```
+
+## Working with Memory
+
+Process different types of content:
+```
+// Process documents
+await runtime.processDocument("path/to/document.pdf");
+await runtime.processUrl("https://example.com");
+await runtime.processText("Important information");
+```
+
+Use the knowledge management tools:
+```bash
+npx folder2knowledge ./docs
+npx knowledge2character my-character.json knowledge.json
+```
+
+## Platform Integration
+
+Set up Discord integration:
+```
+import { DiscordConnector } from "eliza";
+const discord = new DiscordConnector({
+token: process.env.DISCORD_TOKEN,
+runtime: runtime
+});
+await discord.start();
+```
+
+Set up Twitter integration:
+```
+import { TwitterConnector } from "eliza";
+const twitter = new TwitterConnector({
+username: process.env.TWITTER_USERNAME,
+password: process.env.TWITTER_PASSWORD,
+runtime: runtime
+});
+await twitter.start();
+```
+
+
+## Development Commands
+
+Start the server:
+```bash
+pnpm run dev
+```
+
+
+Start the interactive shell:
+```bash
+pnpm run shell
+```
