+## Develop
+
+Don't hesitate to talk about features you want to develop by creating/commenting an issue
+before you start working on them :).
+
+### Prerequisites
+
+First, you should use a server or PC with at least 4GB of RAM. Less RAM may lead to crashes.
+
+Make sure that you have followed
+[the steps](/support/doc/dependencies.md)
+to install the dependencies. You'll need to install **NodeJS 10**.
+
+Fork the github repository,
+and then clone the sources and install node modules:
+
+```
+$ git clone https://github.com/Chocobozzz/PeerTube
+$ git remote add me git@github.com:YOUR_GITHUB_USERNAME/PeerTube.git
+$ cd PeerTube
+$ yarn install --pure-lockfile
+```
+
+Note that development is done on the `develop` branch. If you want to hack on
+Peertube, you should switch to that branch. Also note that you have to repeat
+the `yarn install --pure-lockfile` command.
+
+When you create a new branch you should also tell to use your repo for upload
+not default one. To do just do:
+```
+$ git push --set-upstream me <your branch name>
+```
+
+Then, create a postgres database and user with the values set in the
+`config/default.yaml` file. For instance, if you do not change the values
+there, the following commands would create a new database called `peertube_dev`
+and a postgres user called `peertube` with password `peertube`:
+
+```
+# sudo -u postgres createuser -P peertube
+Enter password for new role: peertube
+# sudo -u postgres createdb -O peertube peertube_dev
+```
+
+Then enable extensions PeerTube needs:
+
+```
+$ sudo -u postgres psql -c "CREATE EXTENSION pg_trgm;" peertube_dev
+$ sudo -u postgres psql -c "CREATE EXTENSION unaccent;" peertube_dev
+```
+
+In dev mode, administrator username is **root** and password is **test**.
+
+### Online development
+
+You can get a complete PeerTube development setup with Gitpod, a free one-click online IDE for GitHub:

+
+### Server side
+
+You can find a documentation of the server code/architecture [here](https://docs.joinpeertube.org/#/contribute-architecture?id=server-code).
+
+To develop on the server-side:
+
+```
+$ npm run dev:server
+```
+
+Then, the server will listen on `localhost:9000`. When server source files
+change, these are automatically recompiled and the server will automatically
+restart.
+
+### Client side
+
+You can find a documentation of the client code/architecture
+[here](https://docs.joinpeertube.org/#/contribute-architecture?id=client-code).
+
+
+To develop on the client side:
+
+```
+$ npm run dev:client
+```
+
+The API will listen on `localhost:9000` and the frontend on `localhost:3000`.
+Client files are automatically compiled on change, and the web browser will
+reload them automatically thanks to hot module replacement.
+
+### Client and server side
+
+The API will listen on `localhost:9000` and the frontend on `localhost:3000`.
+File changes are automatically recompiled, injected in the web browser (no need to refresh manually)
+and the web server is automatically restarted.
+
+```
+$ npm run dev
+```
+
+### Testing the federation of PeerTube servers
+
+Create a PostgreSQL user **with the same name as your username** in order to avoid using the *postgres* user.
+Then, we can create the databases (if they don't already exist):
+
+```
+$ sudo -u postgres createuser you_username --createdb
+$ createdb -O peertube peertube_test{1,2,3}
+```
+
+Build the application and flush the old tests data:
+
+```
+$ npm run build -- --light
+$ npm run clean:server:test
+```
+
+This will run 3 nodes:
+
+```
+$ npm run play
+```
+
+Then you will get access to the three nodes at `http://localhost:900{1,2,3}`
+with the `root` as username and `test{1,2,3}` for the password.
+
+Instance configurations are in `config/test-{1,2,3}.yaml`.
+
+### Unit tests
+
+Create a PostgreSQL user **with the same name as your username** in order to avoid using the *postgres* user.
+
+Then, we can create the databases (if they don't already exist):
+
+```
+$ sudo -u postgres createuser you_username --createdb --superuser
+$ npm run clean:server:test
+```
+
+Build the application and run the unit/integration tests:
+
+```
+$ npm run build -- --light
+$ npm test
+```
+
+If you just want to run 1 test:
+
+```
+$ npm run mocha -- --exit --require ts-node/register/type-check --bail server/tests/api/index.ts
+```
+
+Instance configurations are in `config/test-{1,2,3,4,5,6}.yaml`.
+Note that only instance 2 has transcoding enabled.
