This PR: - reorganizes all documentation pages so they live in the right category - removes lots of legacy docs - contains many improvements to active documentation pages Geth user documentation is now spread across five major categories: - Install and Build: installation and compile instructions - Using Geth: this is for pages about general geth usage. - For dApp Developers: this is for programming guides and functionality specific to dapp development. All the dev guides for mobile framework and Go APIs live here. - JSON-RPC APIs: this has its own section because there is now a sub-page for every name space. I have also added an overview text that explains how to set up the API servers. - For Geth Developers: this is for geth contributors

Most important info first: REMEMBER YOUR PASSWORD and BACKUP YOUR KEYSTORE.
Data Directory
Everything geth persists gets written inside its data directory. The default data
directory locations are platform specific:
- Mac:
~/Library/Ethereum - Linux:
~/.ethereum - Windows:
%APPDATA%\Ethereum
Accounts are stored in the keystore subdirectory. The contents of this directories
should be transportable between nodes, platforms, implementations (C++, Go, Python).
To configure the location of the data directory, the --datadir parameter can be
specified. See CLI Options for more details.
Note the ethash dag is stored at ~/.ethash (Mac/Linux) or
%APPDATA%\Ethash (Windows) so that it can be reused by all clients. You can store this
in a different location by using a symbolic link.
Cleanup
Geth's blockchain and state databases can be removed with:
geth removedb
This is useful for deleting an old chain and sync'ing to a new one. It only affects data directories that can be re-created on synchronisation and does not touch the keystore.
Blockchain Import/Export
Export the blockchain in binary format with:
geth export <filename>
Or if you want to back up portions of the chain over time, a first and last block can be specified. For example, to back up the first epoch:
geth export <filename> 0 29999
Note that when backing up a partial chain, the file will be appended rather than truncated.
Import binary-format blockchain exports with:
geth import <filename>
See https://github.com/ethereum/wiki/wiki/Blockchain-import-export for more info
