 # sendd
+
+sendd allows for direct connections between clients to transfer files. It uses peer.js to assign each an ID, and connect them directly without the need for a file hosting server.
+
+sendd also ships with peer-server, meaning it's completely separate from the peer.js main servers, and doesn't require an API key.
+
+To install:
+    Install npm and nodejs
+    Run:
+    git clone https://github.com/Josh1147582/sendd
+    cd sendd
+    npm install
+    npm start
+
+    Or build and run the docker container at:
+    https://github.com/Josh1147582/sendd-docker
+    
+Usage:
+    Connect to the server (by default) at localhost:3000. Port 9000 must also be open for the peer server to communicate with clients.
