+# OpenThread CLI - SRP (Service Registration Protocol)
+
+## Quick Start
+
+### Build with SRP Server & Client support
+
+Use the `SRP_SERVER=1 SERVICE=1 ECDSA=1` build switches to enable SRP Server API support, and the `SRP_CLIENT=1 ECDSA=1` build switches for SRP Client API support.
+
+Make simulation SRP Server & Client:
+
+```bash
+./bootstrap
+make -f examples/Makefile-simulation SRP_SERVER=1 SRP_CLIENT=1 SERVICE=1 ECDSA=1
+```
+
+## Simulation Example
+
+### Start SRP Server
+
+Start the SRP Server node:
+
+```bash
+./output/simulation/bin/ot-cli-ftd 1
+```
+
+Setup a Thread network and start the SRP Server:
+
+```bash
+> dataset init new

+Done
+```
+
+The SRP Server listening UDP port which is `c002`(`49154`) is included in the Server Data (listed by the `netdata show` command).
+
+### Start SRP Client
+
+Start the SRP Client node:
+
+```bash
+./output/simulation/bin/ot-cli-ftd 2
+```
+
+Join the Thread Network and register a `_ipps._tcp` service:
+
+```bash
+> dataset masterkey 7fcbae4153cc2955c28440c15d4d4219
+Done
+> dataset commit active
+Done
+> ifconfig up

+fded:5114:8263:1fe1:44f9:cc06:4a2d:534
+fe80:0:0:0:38dd:fdf7:5fd:24e
+Done
+> srp client host name my-host
+Done
+> srp client host address fded:5114:8263:1fe1:44f9:cc06:4a2d:534
+Done
+> srp client service add my-service _ipps._tcp 12345
+Done
+srp client start fded:5114:8263:1fe1:68bc:ec03:c1ad:9325 49154
+Done
+```
+
+Make sure the SRP Server address & port are used for the `srp client start` command.
+
+### Verify the service status
+
+Check if the host and service has been successfully registered on the client node:
+
+```bash
+> srp client host
+name:"my-host", state:Registered, addrs:[fded:5114:8263:1fe1:44f9:cc06:4a2d:534]
+Done
+> srp client service
+instance:"my-service", name:"_ipps._tcp", state:Registered, port:12345, priority:0, weight:0
+Done
+```
+
+Make sure it shows `state:Registered` for both host and service commands.
+
+Check the host & service on the server node:
+
+```bash
+> srp server host
+my-host.default.service.arpa.
+    deleted: false
+    addresses: [fded:5114:8263:1fe1:44f9:cc06:4a2d:534]
+Done
+> srp server service
+my-service._ipps._tcp.default.service.arpa.
+    deleted: false
+    port: 12345
+    priority: 0
+    weight: 0
+    TXT: 00
+    host: my-host.default.service.arpa.
+    addresses: [fded:5114:8263:1fe1:44f9:cc06:4a2d:534]
+Done
+```
+
+Make sure it shows `deleted: false` for both host and service commands.
+
+### Remove the service
+
+A service can be removed through the client node:
+
+```bash
+> srp client service remove my-service _ipps._tcp
+Done
+```
+
+Confirm on the server node that the service has been removed:
+
+```bash
+> srp server service
+my-service._ipps._tcp.default.service.arpa.
+    deleted: true
+Done
+```
+
+The service entry is listed because the name of service is not removed.
+
+### Remove the host and service names
+
+A host and service, along with their names, can be removed through the client node:
+
+```bash
+> srp client host remove 1
+Done
+```
+
+Confirm on the server node that no host or service entries are listed:
+
+```bash
+> srp server host
+Done
+> srp server service
+Done
+>
+```
