+**sensor-d4-tls-fingerprinting** is intended to be used to feed a D4 project client (It can be used in standalone though).
+
+# Main features
+
+ * extracts TLS certificates from pcap files or network interfaces
+ * fingerprints TLS client/server interactions with ja3/ja3s
+ * fingerprints TLS interactions with TLSH fuzzy hashing
+ * write certificates in a folder
+ * export in JSON to files, or stdout
+
 # Use
-This project is currently in its very early stage and should not be used in production.
- Check the list of issues.
-## Install dependencies & go get
+This project is currently in development and is subject to change, check the list of issues.
+
+## Compile from source
+### requirements
+ * git
+ * golang >= 1.5
+ * libpcap
+
+``` shell
+#apt install golang git libpcap-dev
+```
+### Go get
+
 ``` shell
-$go get github.com/google/gopacket
-$go get github.com/glaslos/tlsh 
 $go get github.com/D4-project/sensor-d4-tls-fingerprinting
+$cd $GOPATH/github.com/D4-project/sensor-d4-tls-fingerprinting
+$
 ```
-make allows to compile for amd64 and arm ATM.
+A "sensor-d4-tls-fingerprinting" compiled for your architecture should then be in $GOPATH/bin
+Alternatively, use make to compile arm/linux or amd64/linux
