+## About TaskView

-## Architecture
+TaskView is a source-available project and task management platform for small and growing software teams.

-This repository is a monorepo.
+It is designed for teams that need more structure than a simple task board, but do not want the administration overhead and complexity of large enterprise project management systems.

-Main product packages:
+With TaskView, you can manage projects, build custom workflows, track dependencies and time, connect development tools, and automate project operations through the API, webhooks, and MCP.

- - `api` – backend (Node.js)
- - `web` – web client and mobile
- - `taskview-packages/taskview-api` – API client library for building integrations and making HTTP requests
- - `taskview-packages/taskview-db-schemas` - Drizzle ORM schemas
+Your projects. Your infrastructure. Your data.

-Product packages share a single version.
+## Who TaskView is for

+TaskView is a good fit for:

-## Versioning
+* software development teams;
+* startups and small product companies;
+* agencies managing internal and client projects;
+* organizations that require self-hosting and data ownership;
+* teams looking for a lightweight alternative to complex enterprise platforms;
+* developers using AI agents to manage and automate project work;
+* individuals managing technical or personal projects.

-TaskView follows semantic versioning:
- - `MAJOR` – breaking API or data changes
- - `MINOR` – new features
- - `PATCH` – bug fixes
-The version represents the entire product, not individual packages.
+## Why TaskView

+* **Own your data** - run TaskView on your own infrastructure.
+* **Flexible workflows** - configure projects, statuses, boards, roles, and permissions.
+* **Built for development teams** - connect GitHub, GitLab, API clients, and webhooks.
+* **AI-ready** - allow MCP-compatible assistants to work with tasks and projects.
+* **Available everywhere** - use TaskView from the web, iOS, and Android.
+* **No advertising or behavioral tracking** - your project data remains under your control.

-## Status
+## Features

+
+## AI and MCP integration
+
+TaskView includes an MCP server that allows compatible AI tools to interact with your projects.
+
+Depending on the permissions assigned to an API token, an AI assistant can:
+
+* search and inspect projects;
+* create and update tasks;
+* manage task statuses;
+* work with project lists;
+* retrieve task context;
+* automate repetitive project operations.
+
+MCP access can be restricted by permission and by selected projects.
+
+### Connecting an MCP client
+
+The MCP server is published as [`taskview-mcp`](https://www.npmjs.com/package/taskview-mcp) and runs over stdio via `npx` — no install required. You only need a TaskView API token (`tvk_...`) — generate one in your account settings (see [API tokens](https://taskview.tech/docs/features/api-tokens)). Scope the token to the minimum permissions and projects the assistant should reach.
+
+**Claude Code** — add to `.claude/settings.json` (project) or `~/.claude.json` (global):
+
+```json
+{
+  "mcpServers": {
+    "taskview": {
+      "command": "npx",
+      "args": ["-y", "taskview-mcp"],
+      "env": {
+        "TASKVIEW_URL": "https://api.taskview.tech",
+        "TASKVIEW_TOKEN": "tvk_your_token_here"
+      }
+    }
+  }
+}
+```
+
+**Claude Desktop** — add the same `mcpServers` block to `claude_desktop_config.json`.
+
+**Other MCP clients** (Cursor, Windsurf, etc.) — use the same stdio command `npx -y taskview-mcp` with the `TASKVIEW_URL` and `TASKVIEW_TOKEN` environment variables in that client's MCP configuration.
+
+| Variable | Required | Description |
+|---|---|---|
+| `TASKVIEW_URL` | yes | TaskView API server URL (e.g. `https://api.taskview.tech`, or your self-hosted instance) |
+| `TASKVIEW_TOKEN` | yes | API token with the `tvk_` prefix |
+
+See the [TaskView MCP documentation](https://taskview.tech/docs/integrations/mcp) and the [`taskview-mcp` package README](taskview-packages/taskview-mcp/README.md) for the full tool list and more options.
+
+## Quick start
+
+Clone the repository:
+
+```sh
+git clone https://github.com/Gimanh/taskview-community.git
+cd taskview-community
+```
+
+The recommended way to run TaskView is with Docker Compose.
+
+For deployment instructions, environment variables, HTTPS configuration, updates, and backups, see the official documentation:
+
+[TaskView self-hosting documentation](https://taskview.tech/docs/)
+
+> Production deployments should use persistent volumes, HTTPS, regular database backups, and securely generated secrets.
+
+## Repository structure
+
+TaskView is maintained as a monorepo. Product packages share a single version.

+## Technology stack
+
+TaskView is primarily built with:
+
+* Vue
+* Nuxt UI
+* TypeScript
+* Node.js
+* Express
+* PostgreSQL
+* Drizzle ORM
+* Capacitor
+* Docker
+
+## Local development
+
+These instructions are intended for contributors and local development, not for production deployment.
+
+### Prerequisites
+
+You need the following tools:
+
+* Docker
+* PostgreSQL
+* Bun
+* pnpm
+
+On macOS, PostgreSQL can be installed using [Postgres.app](https://postgresapp.com/).
+
+### Install dependencies
+
+From the repository root:

-**Steps:**
-1. Install dependencies:
 ```sh
 pnpm install
 ```

-2. Create an `.env` file in the **api** directory based on `.env.example` and configure your local credentials.
-   
-3. Run the web application:
+### Configure the API
+
+Create an environment file in the `api` directory:
+
+```sh
+cp api/.env.example api/.env
+```
+
+Update `api/.env` with your local database credentials and application configuration.
+
+### Start the web application
+
 ```sh
 cd web
 pnpm dev
 ```

-1. Run the API locally (API uses Bun in development mode):
+### Start the API
+
+In a separate terminal:
+
 ```sh
 cd api
 pnpm start
 ```

-## Building Docker Images
+The API uses Bun in the local development environment.

-You can build Docker images using the provided bash script. The image version is automatically taken from the root `package.json`.
+## Building Docker images
+
+Docker image versions are taken from the root `package.json`.
+
+### Build the images
+
+From the repository root:

-**Steps:**
-1. Build images:
 ```sh
 ./build-dockers.sh
 ```

-2. Verify built images:
+### Verify the images
+
 ```sh
 docker images
 ```
-You should see the following images:

-`gimanhead/taskview-ce-api-server`
-`gimanhead/taskview-ce-webapp`
-`gimanhead/taskview-ce-db-migration`
+The following images should be available:

-3. Test images locally using Docker Compose:
-```sh
-cd api/dev-containers-test
-docker-compose up
+```text
+gimanhead/taskview-ce-api-server
+gimanhead/taskview-ce-webapp
+gimanhead/taskview-ce-db-migration
 ```

-Make sure the image versions match the version defined in the root package.json.
+### Test the images locally
+
+```sh
+cd api/dev-containers-test
+docker compose up
+```
+
+Ensure that image versions match the version defined in the root `package.json`.
+
+## Versioning
+
+TaskView follows [Semantic Versioning](https://semver.org/):
+
+* `MAJOR` - breaking API, database, or compatibility changes;
+* `MINOR` - backward-compatible features;
+* `PATCH` - backward-compatible bug fixes.
+
+The version represents the entire TaskView product, not individual packages.
+
+## Project status
+
+TaskView is under active development.
+
+New features, database migrations, API changes, and breaking changes may be introduced between releases. Review release notes and back up your database before updating a self-hosted installation.
