+Usage for testnets
+==================
+If you would like to give turbo-geth a try, but do not have spare 2Tb on your driver, a good option is to start syncing one of the public testnets, Görli. It syncs much quicker, and does not take so much disk space:
+```sh
+> git clone --recurse-submodules -j8 https://github.com/ledgerwatch/turbo-geth.git
+> cd turbo-geth
+> make tg
+> ./build/bin/tg --datadir goerli --goerli
+```
+
+Please note the `--datadir` option that allows you to store turbo-geth files in a non-default location, in this example, in `goerli` subdirectory of the current directory.

+This is only possible if RPC daemon runs on the same computer as turbo-geth. This mode of operation uses shared memory access to the database of turbo-geth, which is reported to have better performance than accessing via TPC socket (see "For remote DB" section below)

+If both `--chaindata` and `--private.api.addr` options are used for RPC daemon, it works in a "dual" mode. This only works when RPC daemon is on the same computer as turbo-geth. In this mode, most data transfer from turbo-geth to RPC daemon happens via shared memory, only certain things (like new header notifications) happen via TPC socket.
