+--------
+
+This document describes how to install ric-plt/rtmgr, it's dependencies and required system resources.
+
+Introduction
+------------
+Routing Manager is a basic platform service of RIC. It is responsible for distributing routing policies among the other platform components and xApps.
+
+Pre-requisites
+--------------
+* Healthy kubernetes cluster (for Kubernetes testing)
+* Access to the common docker registry (alternatively, you can set up your own private registry for testing: "https://docs.docker.com/registry/deploying/")
+* In case of non-Docker build:
+ * golang 11.1 at least
+ * go-swagger ("https://github.com/go-swagger/go-swagger", v0.19.0)
+ * glide ("https://github.com/Masterminds/glide")
+ * XApp Manager spec file (available in ORAN: "https://gerrit.o-ran-sc.org/r/admin/repos/ric-plt/appmgr" under api folder)
+
+Software Installation and Deployment
+------------------------------------
+This section describes the installation of the ric-plt/rtmgr installation.
+
+Docker Image
+------------
+The Dockerfile located in the project root folder does the following three things:
+
+* As a first step, it creates a build container, fetches XApp Manager's spec file, generates rest api code from swagger spec and builds rtmgr.
+* As a second step, it executes UTs on rtmgr source code.
+* As a third step, it creates the final container from rtmgr binary (Ubuntu based).
+
+For a docker build execute `docker build --tag=rtmgr-build:test .` in the project root directory (feel free to replace the name:tag with your own)
+
+Linux Binary
+------------
+* Compiling without Docker involves some manual steps before compiling directly with "go build".
+* The XApp manager's spec file must be fetched, then api generated with swagger. (these steps are included in the Dockerfile).
+* After the code is generated, glide can install the dependencies of rtmgr.
+* Make sure you set your GOPATH variable correctly (example: $HOME/go/src/routing-manager)
+* Code generation and building example (from project root folder):
+
+ * git clone https://gerrit.o-ran-sc.org/r/ric-plt/appmgr && cp appmgr/api/appmgr_rest_api.yaml api/
+ * swagger generate server -f api/routing_manager.yaml -t pkg/ --exclude-main -r LICENSE
+ * swagger generate client -f api/appmgr_rest_api.yaml -t pkg/ -m appmgr_model -c appmgr_client -r LICENSE
+ * glide install --strip-vendor
+ * go build cmd/rtmgr.go
+
+NOTE: before doing a docker build it is advised to remove any generated files and vendor packages:
+assuming that you stand in project root dir
+
+ rm -rf appmgr vendor pkg/appmgr_* pkg/models pkg/restapi
+
+Command line arguments
+----------------------
+Routing manager binary can be called with `-h` flag when it displays the available command line arguments and it's default value.
+
+Example:
+
+Usage of ./rtmgr:
+ -configfile string
+ Routing manager's configuration file path (default "/etc/rtmgrcfg.json")
+ -filename string

+ -rpe string
+ Route Policy Engine to be used. Valid values are: 'rmrpush | rmrpub' (default "rmrpush")
+ -sbi string
+ Southbound interface module to be used. Valid values are: 'nngpush | nngpub' (default "nngpush")
+ -sbi-if string
