+An easy-to-implement networking protocol for OpenComputers. Not to be confused with the [French computer network of the same name](https://en.wikipedia.org/wiki/Minitel).
 
-Here is a paragraph break, I suppose.
+Minitel aims to implement layers 3, 4 and 5 of the OSI model.
 
-Here's another. ]]
+## Layers
+### Layer 3
+[Layer 3](protocol-3.md) implements addressing, meshing and datagram transmission.
+
+### Layer 4
+[Layer 4](protocol-4.md) implements ordered message delivery
+
+### Layer 5
+[Layer 5](protocol-5.md) implements reliable, ordered, bidirectional streams.
+
+## Implementations
+### OpenOS
+
+- [Reference implementation for OpenOS](OpenOS/README.md)
+
+### KittenOS
+
+- [Minitel for KittenOS NEO](KittenOS/README.md)
+
+### Embedded devices
+
+- [Microtel](Embedded/microtel/README.md)
+
+## Application-layer protocols
+This repository also contains a number of implementations and specifications for application-layer protocols using Minitel.
+
+- [FRequest](FRequest/FRequest-protocol.md)
+- [Minitel Mail](MMail/MMail-protocol.md)
+
+## Development and discussion
+Code and documentation is hosted in the [Github repository](https://github.com/XeonSquared/OC-Minitel).
+
+Discussion takes place in, among other places, the [#SKS IRC channel on EsperNet](irc://irc.esper.net/#SKS) ([webchat](https://webchat.esper.net/?channels=SKS))
