+# Huly Platform API Client
+
+A TypeScript client library for interacting with the Huly Platform API.
+
+## Installation
+
+In order to be able to install required packages, you will need to obtain GitHub access token. You can create a token by following the instructions [here](https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-npm-registry#authenticating-with-a-personal-access-token).
+
+```bash
+npm install @hcengineering/api-client
+```
+
+## Authentication
+
+There are two ways to connect to the platform, using email and password, or using token.
+
+Parameters:
+
+- `url`: URL of the Huly instance
+- `options`: Connection options
+  - `workspace`: Name of the workspace to connect to
+  - `token`: Optional authentication token
+  - `email`: Optional user email
+  - `password`: Optional user password
+  - `connectionTimeout`: Optional connection timeout
+  - `socketFactory`: Optional socket factory
+
+### Using Email and Password
+
+```ts
+const client = await connect('http://localhost:8087', {
+  email: 'user1',
+  password: '1234',
+  workspace: 'ws1'
+})
+
+...
+
+await client.close()
+```
+
+### Using Token
+
+```ts
+const client = await connect('http://localhost:8087', {
+  token: '...',
+  workspace: 'ws1'
+})
+
+...
+
+await client.close()
+```
+

+  - `sort`: Sorting criteria
+  - `lookup`: Lookup criteria
+  - `projection`: Projection criteria
+  - `total`: If specified total will be returned
+
+Example:
+
+```ts
+import contact from '@hcengineering/contact'
+
