-## Building the sources
+## Development
 
-Node.js >= 8 and npm >= 6 are required.
-
-On Debian/Ubuntu systems, the required packages can be installed with:
-```
-sudo apt-get install npm nodejs
-cd jitsi-meet
-npm install
-```
-
-To build the Jitsi Meet application, just type
-```
-make
-```
-
-### Working with the library sources (lib-jitsi-meet)
-
-By default the library is build from its git repository sources. The default dependency path in package.json is :
-```json
-"lib-jitsi-meet": "jitsi/lib-jitsi-meet",
-```
-
-To work with local copy you must change the path to:
-```json
-"lib-jitsi-meet": "file:///Users/name/local-lib-jitsi-meet-copy",
-```
-
-To make the project you must force it to take the sources as 'npm update':
-```
-npm install lib-jitsi-meet --force && make
-```
-
-Or if you are making only changes to the library:
-```
-npm install lib-jitsi-meet --force && make deploy-lib-jitsi-meet
-```
-
-Alternative way is to use [npm link](https://docs.npmjs.com/cli/link).
-It allows to link `lib-jitsi-meet` dependency to local source in few steps:
-
-```bash
-cd lib-jitsi-meet
-
-#### create global symlink for lib-jitsi-meet package
-npm link
-
-cd ../jitsi-meet
-
-#### create symlink from the local node_modules folder to the global lib-jitsi-meet symlink
-npm link lib-jitsi-meet
-```
-
- After changes in local `lib-jitsi-meet` repository, you can rebuild it with `npm run install` and your `jitsi-meet` repository will use that modified library.
-Note: when using node version 4.x, the make file of jitsi-meet do npm update which will delete the link. It is no longer the case with version 6.x.
-
-If you do not want to use local repository anymore you should run
-```bash
-cd jitsi-meet
-npm unlink lib-jitsi-meet
-npm install
-```
-### Running with webpack-dev-server for development
-
-Use it at the CLI, type
-```
-make dev
-```
-
-By default the backend deployment used is `beta.meet.jit.si`. You can point the Jitsi-Meet app at a different backend by using a proxy server. To do this, set the WEBPACK_DEV_SERVER_PROXY_TARGET variable:
-```
-export WEBPACK_DEV_SERVER_PROXY_TARGET=https://your-example-server.com
-make dev
-```
-
-The app should be running at https://localhost:8080/

 If you want to use a SDK that is built from source, you will likely benefit from composing a local Maven repository that contains these dependencies. The text below describes how you create a repository that includes both the SDK as well as these dependencies. For illustration purposes, we'll define the location of this local Maven repository as `/tmp/repo`

 This will pull in the dependencies in either binary format, or in source code format, somewhere under /node_modules/
 
-At the time of writing, there are two packages pulled in in binary format.
+Third-party React Native _modules_, which Jitsi Meet SDK for Android depends on, are download by NPM in source code

-
-Third-party React Native _modules_, which Jitsi Meet SDK for Android depends on, are download by NPM in source code form. These need to be assembled into Maven artifacts, and then published to your local Maven repository. The SDK project facilitates this.
-
-To prepare, Configure the Maven repositories in which you are going to publish the SDK artifacts/binaries. In `android/sdk/build.gradle` as well as in `android/build.gradle` modify the lines that contain:
-
-    "file:${rootProject.projectDir}/../../jitsi-maven-repository/releases"
-
-Change this value (which represents the Maven repository location used internally by the Jitsi Developers) to the location of the repository that you'd like to use:
-
-    "file:/tmp/repo"
-
-Make sure to do this in both files! Each file should require one line to be changed.
-
-To prevent artifacts from previous builds affecting you're outcome, it's good to start with cleaning your work directories:
-
-    $ ./gradlew clean
-
-To create the release assembly for any _specific_ third-party React Native module that you need, you can execture the following commands, replace the module name in the examples below.
-
-    $ ./gradlew :react-native-webrtc:assembleRelease
-    $ ./gradlew :react-native-webrtc:publish
-
-You build and publish the SDK itself in the same way:
-
-    $ ./gradlew :sdk:assembleRelease
-    $ ./gradlew :sdk:publish
-
-Alternatively, you can assemble and publish _all_ subprojects, which include the react-native modules, but also the SDK itself, with a single command:
-
-    $ ./gradlew clean assembleRelease publish
+This will build and publish the SDK, and all of its dependencies to the specified Maven repository (`/tmp/repo`) in
