== The Basics ==
 * [source:docs/about.html about.html]: the basic shape of a Tahoe filesystem and the security properties that it offers
 * [source:docs/architecture.txt architecture.txt]: the design decisions that give the filesystem its current behavior
 * [wiki:UseCases UseCases]: the ways in which Tahoe should be useful
 * [source:docs/webapi.txt webapi.txt]: everything you need to know to use Tahoe from your own program
 * [source:roadmap.txt roadmap.txt]: how the functionality has been incrementally improved so far, and what improvements we plan to make next
 * [source:docs/codemap.txt codemap.txt]: the software practices and organization of the source code
 * [source:docs/configuration.txt configuration.txt]: how to configure a tahoe node and what persistent state it creates

== Detailed Design Docs ==
 * [source:docs/mutable.txt mutable.txt], explaining the interesting crypto tricks that go into secure distributed mutable files
 * FileEncoding, explaining how we turn files into shares, with verifiable hashes; This is mostly concerned with chunking and Merkle trees.
 * ShareEncoding, explaining how we turn a chunk into shares: Reed-Solomon, FEC, that stuff

== Outstanding Issues ==
 * [wiki:PeerSelection PeerSelection], explaining how a Tahoe node chooses which other nodes to use for uploading and downloading files (which raises some unsolved issues in balancing scalability, robustness, performance, and simplicity)  
 * ChangingFilesWhileCopyingThem : what are the semantics of the "upload" action? the upload takes
   non-zero time: what happens if the file is changed during that time?
