 ### Configuring

+Default configuration file is located in `config/` folder.
 
-To change the default configuration values, create local files that override the parameters you need to change. You can use `environment.template.ts` as a starting point.
+To override the default configuration values, create local files that override the parameters you need to change. You can use `config.example.yml` as a starting point.
 
--	Create a new `environment.dev.ts` file in `src/environments/` for a `development` environment;
+-	Create a new `config.(dev or development).yml` file in `config/` for a `development` environment;
--	Create a new `environment.prod.ts` file in `src/environments/` for a `production` environment;

+The following non-convention settings:
 
 ```bash
 DSPACE_HOST # The host name of the angular application
 DSPACE_PORT # The port number of the angular application
 DSPACE_NAMESPACE # The namespace of the angular application
 DSPACE_SSL # Whether the angular application uses SSL [true/false]
+```
 
-DSPACE_REST_HOST # The host name of the REST application
+All other settings can be set using the following convention for naming the environment variables:
-DSPACE_REST_PORT # The port number of the REST application
+
-DSPACE_REST_NAMESPACE # The namespace of the REST application
+1. replace all `.` with `_`
-DSPACE_REST_SSL # Whether the angular REST uses SSL [true/false]
+2. convert all characters to upper case
+3. prefix with `DSPACE_`

+
+```bash

+
+# The port number of the REST application

+dspace.rest.nameSpace => DSPACE_REST_NAMESPACE
+
+# Whether the angular REST uses SSL [true/false]
+dspace.rest.ssl => DSPACE_REST_SSL

+DSPACE_UI_HOST => DSPACE_HOST
+DSPACE_UI_PORT => DSPACE_PORT
+DSPACE_UI_NAMESPACE => DSPACE_NAMESPACE
+DSPACE_UI_SSL => DSPACE_SSL
 ```
 
 The same settings can also be overwritten by setting system environment variables instead, E.g.:
 ```bash
 export DSPACE_HOST=api7.dspace.org
+export DSPACE_UI_PORT=4200
 ```
 
-The priority works as follows: **environment variable** overrides **variable in `.env` file** overrides **`environment.(prod, dev or test).ts`** overrides **`environment.common.ts`**
+The priority works as follows: **environment variable** overrides **variable in `.env` file** overrides external config set by `DSPACE_APP_CONFIG_PATH` overrides **`config.(prod or dev).yml`**
 
-These configuration sources are collected **at build time**, and written to `src/environments/environment.ts`.  At runtime the configuration is fixed, and neither `.env` nor the process' environment will be consulted.
+These configuration sources are collected **at run time**, and written to `dist/browser/assets/config.json` for production and `src/app/assets/config.json` for development.
+
+The configuration file can be externalized by using environment variable `DSPACE_APP_CONFIG_PATH`.
 
 #### Using environment variables in code
 To use environment variables in a UI component, use:
 
 ```typescript
-import { environment } from '../environment.ts';
+import { AppConfig, APP_CONFIG } from 'src/config/app-config.interface';
+...
+constructor(@Inject(APP_CONFIG) private appConfig: AppConfig) {}
+...
 ```
 
-This file is generated by the script located in `scripts/set-env.ts`. This script will run automatically before every build, or can be manually triggered using the appropriate `config` script in `package.json`
+or
+
+```typescript
+import { environment } from '../environment.ts';
+```

 The test files can be found in the `./cypress/integration/` folder.
 
 Before you can run e2e tests, two things are required:
-1. You MUST have a running backend (i.e. REST API). By default, the e2e tests look for this at http://localhost:8080/server/ or whatever `rest` backend is defined in your `environment.prod.ts` or `environment.common.ts`. You may override this using env variables, see [Configuring](#configuring).

 2. Your backend MUST include our Entities Test Data set. Some tests run against a (currently hardcoded) Community/Collection/Item UUID. These UUIDs are all valid for our Entities Test Data set. The Entities Test Data set may be installed easily via Docker, see https://github.com/DSpace/DSpace/tree/main/dspace/src/main/docker-compose#ingest-option-2-ingest-entities-test-data
 
 Run `ng e2e` to kick off the tests. This will start Cypress and allow you to select the browser you wish to use, as well as whether you wish to run all tests or an individual test file.  Once you click run on test(s), this opens the [Cypress Test Runner](https://docs.cypress.io/guides/core-concepts/test-runner) to run your test(s) and show you the results.

 # Configuration
 
-Default configuration file is located in `src/environments/` folder. All configuration options should be listed in the default configuration file `src/environments/environment.common.ts`. Please do not change this file directly! To change the default configuration values, create local files that override the parameters you need to change. You can use `environment.template.ts` as a starting point.
+Default configuration file is located at `config/config.yml`. All configuration options should be listed in the default typescript file `src/config/default-app-config.ts`. Please do not change this file directly! To override the default configuration values, create local files that override the parameters you need to change. You can use `config.example.yml` as a starting point.
 
--	Create a new `environment.dev.ts` file in `src/environments/` for `development` environment;
+-	Create a new `config.(dev or development).yml` file in `config/` for `development` environment;
--	Create a new `environment.prod.ts` file in `src/environments/` for `production` environment;
+-	Create a new `config.(prod or production).yml` file in `config/` for `production` environment;
 
-Some few configuration options can be overridden by setting environment variables. These and the variable names are listed below.
+Alternatively, create a desired app config file at an external location and set the path as environment variable `DSPACE_APP_CONFIG_PATH`.
+
+e.g.
+```
+DSPACE_APP_CONFIG_PATH=/usr/local/dspace/config/config.yml
+```
+
+Configuration options can be overridden by setting environment variables.
 
 ## Nodejs server
 When you start dspace-angular on node, it spins up an http server on which it listens for incoming connections. You can define the ip address and port the server should bind itsself to, and if ssl should be enabled not. By default it listens on `localhost:4000`. If you want it to listen on all your network connections, configure it to bind itself to `0.0.0.0`.
 
 To change this configuration, change the options `ui.host`, `ui.port` and `ui.ssl` in the appropriate configuration file (see above):
-```
+
-export const environment = {
+```yaml
-  // Angular UI settings.
+ui:
-  ui: {
+  ssl: false

+  DSPACE_UI_PORT=4000

 ## DSpace's REST endpoint
 dspace-angular connects to your DSpace installation by using its REST endpoint. To do so, you have to define the ip address, port and if ssl should be enabled. You can do this in a configuration file (see above) by adding the following options:
 
-```
+```yaml

+## Environment variable naming convention
+
+Settings can be set using the following convention for naming the environment variables:
+
+1. replace all `.` with `_`
+2. convert all characters to upper case
+3. prefix with `DSPACE_`
+
+e.g.
+
