 When starting a container running ipfs for the first time with an empty data directory, it will call `ipfs init` to initialize configuration files and generate a new keypair. At this time, you can choose which profile to apply using the `IPFS_PROFILE` environment variable:
 
-    docker run -d --name ipfs_host -e IPFS_PROFILE=server -v $ipfs_staging:/export -v $ipfs_data:/data/ipfs -p 4001:4001 -p 127.0.0.1:8080:8080 -p 127.0.0.1:5001:5001 ipfs/go-ipfs:latest

 It is possible to initialize the container with a swarm key file (`/data/ipfs/swarm.key`) using the variables `IPFS_SWARM_KEY` and `IPFS_SWARM_KEY_FILE`. The `IPFS_SWARM_KEY` creates `swarm.key` with the contents of the variable itself, whilst `IPFS_SWARM_KEY_FILE` copies the key from a path stored in the variable. The `IPFS_SWARM_KEY_FILE` **overwrites** the key generated by `IPFS_SWARM_KEY`.
 
-    docker run -d --name ipfs_host -e IPFS_SWARM_KEY=<your swarm key> -v $ipfs_staging:/export -v $ipfs_data:/data/ipfs -p 4001:4001 -p 127.0.0.1:8080:8080 -p 127.0.0.1:5001:5001 ipfs/go-ipfs:latest

 The swarm key initialization can also be done using docker secrets **(requires docker swarm or docker-compose)**:
 
     cat your_swarm.key | docker secret create swarm_key_secret -

-
-### In Version
-
-0.4.18
-
-### State
-
-Candidate, disabled by default but it will be enabled by default in 0.6.0.
-
-### How to enable
-
-Modify your ipfs config:
-
-```
-ipfs config --json Experimental.QUIC true
-```
-
-For listening on a QUIC address, add it to the swarm addresses, e.g. `/ip4/0.0.0.0/udp/4001/quic`.
-
-
-### Road to being a real feature
-
-- [ ] The IETF QUIC specification needs to be finalized.
-- [ ] Make sure QUIC connections work reliably
-- [ ] Make sure QUIC connection offer equal or better performance than TCP connections on real-world networks
-- [ ] Finalize libp2p-TLS handshake spec.
