+# Tool to send and receive files using Tox NGC FileTransfers
+currently on prototype FT1
+
+## Example
+
+### sender (seeder)
+`$ tox_ngc_ft1_tool -F sender.tox -G <ngc_chat_id> -a sha1_info -f file_to_transfer`
+
+this will print this tools tox_id and the generated info_hash
+
+### receivers (leechers)
+`$ tox_ngc_ft1_tool -F sender.tox -G <ngc_chat_id> -a sha1_info -D <info_hash>`
+
+this will first download the info using the info_hash and then all the file chunks listed in the info
+while simultaneously resharing allready downloaded chunks and info (swarming)
+to increase the amount of parallel chunk down/up loads, you can increase the value with the -I and -O option. the default for -I is 32 and for -O 16, which are relatively low numbers, which in practice can get you up to ~700KiB/s.
+
+## Usage
+
+```
+$ tox_ngc_ft1_tool
+~~~ HELP ~~~
+ meta:
+ -v version info
+ -V verbose
+ -h help
+
+ connectivity:
+ -G <chat_id>
+ -F profile.tox
+ -N <self_name> (defaults to 'tox_ngc_ft1_tool')
+ will print friend id at startup
+ will autoaccept any invite
+ if no -F given, will not save profile.
+ if profile exists load, otherwise create new
+
+ transfer variant:
+ -a id1/sha1_single/sha1_info/sha2_single/sha2_info
+
+ send:
+ -f send_this_file.zip
+
+ receive:
+ -d dump/everything/in/this/dir
+ -D <id/hash> (what to dl)
+
+!!! ADVANCED !!!
+ tox:
+ -L disable local discovery
+ -U disable udp
+ -P proxy_host proxy_port
+ -p tox_port (bind tox to that port)
+
+ FT1:
+ --ft_ack_per_packet
+ --ft_init_retry_timeout_after
+ --ft_sending_give_up_after
+
+ transfer logic:
+ -I <max_incoming_transfers>
+ -O <max_outgoing_transfers>
+```
