+# Misskey
+
+[![][travis-badge]][travis-link]
+[![][dependencies-badge]][dependencies-link]
+[![][mit-badge]][mit]
+
+A miniblog-based SNS.
+
+## Dependencies
+* Node.js
+* MongoDB
+* Redis
+* GraphicsMagick
+
+## Optional dependencies
+* Elasticsearch
+
+## Get started
+Misskey requires two domains called the primary domain and the secondary domain.
+
+* The primary domain is used to provide main service of Misskey.
+* The secondary domain is used to avoid vulnerabilities such as XSS.
+
+**Ensure that the secondary domain is not a subdomain of the primary domain.**
+
+## Build
+1. `git clone git://github.com/syuilo/misskey.git`
+2. `cd misskey`
+3. `npm install`
+4. `npm run config`
+5. `npm run build`
+
+## Launch
+`npm start`
