+Onionr can provide evidence of when a block was inserted by requesting other users to sign a hash of the current time with the block data hash: sha3_256(time + sha3_256(block data)).
 
 This can be done either by the creator of the block prior to generation, or by any node after insertion.

+In addition, randomness beacons such as the one operated by [NIST](https://beacon.nist.gov/home) or the hash of the latest blocks in a cryptocurrency network could be used to affirm that a block was at least not *created* before a given time.

 **The main repo for this software is at https://gitlab.com/beardog/Onionr/**
 
-**Roadmap/features:**
+
+# Summary
+
+Onionr is a decentralized, peer-to-peer data storage network, designed to be anonymous and resistant to (meta)data analysis and spam.
+
+Onionr can be used for mail, as a social network, instant messenger, file sharing software, or for encrypted group discussion.
+
+# Roadmap/features
 
 Check the [Gitlab Project](https://gitlab.com/beardog/Onionr/milestones/1) to see progress towards the alpha release.
 
+## Core internal features
+
 * [X] Fully p2p/decentralized, no trackers or other single points of failure
-* [X] High level of anonymity
+* [X] End to end encryption of user data
-* [ ] End to end encryption where applicable
 * [X] Optional non-encrypted blocks, useful for blog posts or public file sharing
-* [ ] Easy API system for integration to websites
+* [X] Easy API system for integration to websites
+* [ ] Metadata analysis resistance (being improved)
 
-# Development
 
-This software is in heavy development. If for some reason you want to get involved, get in touch first.
+## Other features
 
-**Onionr API and functionality is subject to non-backwards compatible change during development**
+**Onionr API and functionality is subject to non-backwards compatible change during pre-alpha development**
