+# @langchain/cohere
+
+This package contains the LangChain.js integrations for Cohere through their SDK.
+
+## Installation
+
+```bash npm2yarn
+npm install @langchain/cohere @langchain/core
+```
+
+This package, along with the main LangChain package, depends on [`@langchain/core`](https://npmjs.com/package/@langchain/core/).
+If you are using this package with other LangChain packages, you should make sure that all of the packages depend on the same instance of @langchain/core.
+You can do so by adding appropriate field to your project's `package.json` like this:
+
+```json
+{
+  "name": "your-project",
+  "version": "0.0.0",
+  "dependencies": {
+    "@langchain/cohere": "^0.0.1",
+    "@langchain/core": "^0.3.0",
+  },
+  "resolutions": {
+    "@langchain/core": "0.3.0"
+  },
+  "overrides": {
+    "@langchain/core": "0.3.0"
+  },
+  "pnpm": {
+    "overrides": {
+      "@langchain/core": "0.3.0"
+    }
+  }
+}
+```
+
+The field you need depends on the package manager you're using, but we recommend adding a field for the common `yarn`, `npm`, and `pnpm` to maximize compatibility.
+
+## Chat Models
+
+This package contains the `ChatCohere` class, which is the recommended way to interface with the Cohere series of models.
+
+To use, install the requirements, and configure your environment.
+
+```bash
+export COHERE_API_KEY=your-api-key
+```
+
+Then initialize
+
+```typescript
+import { HumanMessage } from "@langchain/core/messages";
+import { ChatCohere } from "@langchain/cohere";
+
+const model = new ChatCohere({
+  apiKey: process.env.COHERE_API_KEY,
+});
+const response = await model.invoke([new HumanMessage("Hello world!")]);
+```
+
+### Streaming
+
+```typescript
+import { HumanMessage } from "@langchain/core/messages";
+import { ChatCohere } from "@langchain/cohere";
+
+const model = new ChatCohere({
+  apiKey: process.env.COHERE_API_KEY,
+});
+const response = await model.stream([new HumanMessage("Hello world!")]);
+```
+
+## Embeddings
+
+This package also adds support for `CohereEmbeddings` embeddings model.
+
+```typescript
+import { ChatCohere } from "@langchain/cohere";
+
+const embeddings = new ChatCohere({
+  apiKey: process.env.COHERE_API_KEY,
+});
+const res = await embeddings.embedQuery("Hello world");
+```
+
+## Development
+
+To develop the `@langchain/cohere` package, you'll need to follow these instructions:
+
+### Install dependencies
+
+```bash
+yarn install
+```
+
+### Build the package
+
+```bash
+yarn build
+```
+
+Or from the repo root:
+
+```bash
+yarn build --filter=@langchain/cohere
+```
+
+### Run tests
+
+Test files should live within a `tests/` file in the `src/` folder. Unit tests should end in `.test.ts` and integration tests should
+end in `.int.test.ts`:
+
+```bash
+$ yarn test
+$ yarn test:int
+```
+
+### Lint & Format
+
+Run the linter & formatter to ensure your code is up to standard:
+
+```bash
+yarn lint && yarn format
+```
+
+### Adding new entrypoints
+
+If you add a new file to be exported, either import & re-export from `src/index.ts`, or add it to the `entrypoints` field in the `config` variable located inside `langchain.config.js` and run `yarn build` to generate the new entrypoint.
