+# @mermaidchart/cli
+
+CLI for interacting with https://MermaidChart.com, the platform that makes collaborating with Mermaid diagrams easy!
+
+## Usage
+
+```bash
+mermaid-chart <command>
+```
+
+Use `--help` to see options!
+
+```bash
+mermaid-chart --help
+```
+
+`@mermaidchart/cli` allows you to easily sync local diagrams with your diagrams
+on https://mermaidchart.com.
+
+### `login`
+
+Firstly, go to https://www.mermaidchart.com/app/user/settings and generate an
+API key, which you can then setup by running:
+
+```bash
+mermaid-chart login
+```
+
+### `link` an existing Mermaid diagram to MermaidChart.com
+
+You can link a local Mermaid diagram to MermaidChart using:
+
+```bash
+mermaid-chart link ./path/to/my/mermaid-digram.mmd
+```
+
+This will add an `id: xxxx-xxxxx-xxxxx` field to your diagram's YAML frontmatter,
+which points to the diagram on MermaidChart.com:
+
+````markdown
+```mermaid
+---
+title: My diagram
+id: xxxx-xxxxx-xxxxx # this field is created by @mermaidchart/cli
+---
+flowchart
+  x[My Diagram]
+```
+````
+
+### `push` local changes to MermaidChart.com
+
+Once you've made some local changes, you can `push` your changes to MermaidChart.com
+
+```console
+$ mermaid-chart push ./path/to/my/mermaid-digram.mmd
+✅ - ./path/to/my/mermaid-digram.mmd was pushed
+```
+
+### `pull` changes from MermaidChart.com
+
+You can use `pull` to pull down changes from MermaidChart.com.
+
+```console
+$ mermaid-chart pull ./path/to/my/mermaid-digram.mmd
+✅ - ./path/to/my/mermaid-digram.mmd was updated
+```
+
+Or use the `--check` flag to throw an error if your local file would have been
+updated:
+
+```console
+$ mermaid-chart pull ./path/to/my/mermaid-digram.mmd
+❌ - ./path/to/my/mermaid-digram.mmd would be updated
+```
