 ## Run the tests
-### Elasticsearch
 
-For running integration tests, Elasticsearch is required to be available at localhost:9200/
+To run the unit tests from the repo directory:
 
-The easiest way to start it is using docker with:
-```bash
-make elastic-docker
-```
-
-Alternative installation methods are available [at Elasticsearch website](https://www.elastic.co/guide/en/elasticsearch/reference/current/install-elasticsearch.html).
-
-To run the unit and integration tests from the repo directory:
  ```
  python -m unittest discover tests.unit
-python -m unittest discover tests.integration
  ```
 
 ## Usage
 
 To start the API server:
-```
+    `lbrynet start`
-lbrynet start
-```
 
-Whenever the code inside [lbry-sdk/lbry](./lbry)
-is modified we should run `make install` to recompile the `lbrynet`
-executable with the newest code.
-
-## Development
-
-When developing, remember to enter the environment,
-and if you wish start the server interactively.
-```bash
-$ source lbry-venv/bin/activate
-
-(lbry-venv) $ python lbry/extras/cli.py start
-```
-
-Parameters can be passed in the same way.
-```bash
-(lbry-venv) $ python lbry/extras/cli.py wallet balance
-```
-
-If a Python debugger (`pdb` or `ipdb`) is installed we can also start it
-in this way, set up break points, and step through the code.
-```bash
-(lbry-venv) $ pip install ipdb
-
-(lbry-venv) $ ipdb lbry/extras/cli.py
-```

 LBRY is a decentralized peer-to-peer protocol for publishing and accessing digital content. It utilizes the [LBRY blockchain](https://github.com/lbryio/lbrycrd) as a global namespace and database of digital content. Blockchain entries contain searchable content metadata, identities, rights and access rules. LBRY also provides a data network that consists of peers (seeders) uploading and downloading data from other peers, possibly in exchange for payments, as well as a distributed hash table used by peers to discover other peers.
 
 LBRY SDK for Python is currently the most fully featured implementation of the LBRY Network protocols and includes many useful components and tools for building decentralized applications. Primary features and components include:
 
- * Built on Python 3.7 and `asyncio`.
+ * Built on Python 3.7+ and `asyncio`.
  * Kademlia DHT (Distributed Hash Table) implementation for finding peers to download from and announcing to peers what we have to host ([lbry.dht](https://github.com/lbryio/lbry-sdk/tree/master/lbry/dht)).
  * Blob exchange protocol for transferring encrypted blobs of content and negotiating payments ([lbry.blob_exchange](https://github.com/lbryio/lbry-sdk/tree/master/lbry/blob_exchange)).
  * Protobuf schema for encoding and decoding metadata stored on the blockchain ([lbry.schema](https://github.com/lbryio/lbry-sdk/tree/master/lbry/schema)).

-Schema
-=====
-
-Those files are generated from the [types repo](https://github.com/lbryio/types). If you are modifying/adding a new type, make sure it is cloned in the same root folder as the SDK repo, like:
-
-```
-repos/
-    - lbry-sdk/
-    - types/
-```
-
-Then, [download protoc 3.2.0](https://github.com/protocolbuffers/protobuf/releases/tag/v3.2.0), add it to your PATH. On linux it is:
-
-```bash
-cd ~/.local/bin
-wget https://github.com/protocolbuffers/protobuf/releases/download/v3.2.0/protoc-3.2.0-linux-x86_64.zip
-unzip protoc-3.2.0-linux-x86_64.zip bin/protoc -d..
-```
-
-Finally, `make` should update everything in place.
-
-
-### Why protoc 3.2.0?
-Different/newer versions will generate larger diffs and we need to make sure they are good. In theory, we can just update to latest and it will all work, but it is a good practice to check blockchain data and retro compatibility before bumping versions (if you do, please update this section!).
