 # Using the gRPC API
 
-By default the gRPC API is currently not turned on by default. There are a couple ways that this can be enabled
+gRPC is the main API for interfacing with CORE.
-to use.
 
-## Enabling gRPC
+## HTTP Proxy
-
-### HTTP Proxy
 
 Since gRPC is HTTP2 based, proxy configurations can cause issue. Clear out your proxy when running if needed.
 
-### Daemon Options
-
-The gRPC API is enabled through options provided to the **core-daemon**.
-
-```shell
-usage: core-daemon [-h] [-f CONFIGFILE] [-p PORT] [-n NUMTHREADS] [--ovs]
-                   [--grpc] [--grpc-port GRPCPORT]
-                   [--grpc-address GRPCADDRESS]
-
-CORE daemon v.5.3.0 instantiates Linux network namespace nodes.
-
-optional arguments:
-  -h, --help            show this help message and exit
-  -f CONFIGFILE, --configfile CONFIGFILE
-                        read config from specified file; default =
-                        /etc/core/core.conf
-  -p PORT, --port PORT  port number to listen on; default = 4038
-  -n NUMTHREADS, --numthreads NUMTHREADS
-                        number of server threads; default = 1
-  --ovs                 enable experimental ovs mode, default is false
-  --grpc                enable grpc api, default is false
-  --grpc-port GRPCPORT  grpc port to listen on; default 50051
-  --grpc-address GRPCADDRESS
-                        grpc address to listen on; default localhost
-```
-
-### Enabling in Service Files
-
-Modify service files to append the --grpc options as desired.
-
-For sysv services /etc/init.d/core-daemon
-```shell
-CMD="PYTHONPATH=/usr/lib/python3.6/site-packages python3 /usr/bin/$NAME --grpc"
-```
-
-For systemd service /lib/systemd/system/core-daemon.service
-```shell
-ExecStart=@PYTHON@ @bindir@/core-daemon --grpc
-```
-
-### Enabling from Command Line
-
-```shell
-sudo core-daemon --grpc
-```
-
 ## Python Client
 
 A python client wrapper is provided at **core.api.grpc.client.CoreGrpcClient**.
