+ $ python --version
 
-If you are on Linux and using PyCharm, generates initial configs:
-```bash
-make idea
-```
+ Install packages:
+ $ make install
 
-To verify your installation, `which lbrynet` should return a path inside
-of the `lbry-venv` folder.
-```bash
-(lbry-venv) $ which lbrynet
-/opt/lbry-sdk/lbry-venv/bin/lbrynet
-```
+ If you are on Linux and using PyCharm, generates initial configs:
+ $ make idea
+ ```
 
-To exit the virtual environment simply use the command `deactivate`.
+To verify your installation, `which lbrynet` should return a path inside of the `lbry-venv` folder created by the `python3.7 -m venv lbry-venv` command.
 
 ### Windows
 
-Clone the repository:
-```bash
-git clone https://github.com/lbryio/lbry-sdk.git
-cd lbry-sdk
-```
+To install on Windows:
 
-Create a Python virtual environment for lbry-sdk:
-```bash
-python -m venv lbry-venv
-```
+ ```
+ Clone the repository:
+ > git clone https://github.com/lbryio/lbry-sdk.git
+ > cd lbry-sdk
 
-Activate virtual environment:
-```bash
-lbry-venv\Scripts\activate
-```
+ Create a Python virtual environment for lbry-sdk:
+ > python -m venv lbry-venv
 
-Install packages:
-```bash
-pip install -e .
-```
+ Activating lbry-sdk virtual environment:
+ > lbry-venv\Scripts\activate
+
+ Install packages:
+ > cd torba
+ > pip install -e .
+ > cd ../lbry
+ > pip install -e .
+ ```
 
 ## 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
-```
+ ```
+ python -m unittest discover -s lbry tests.unit
+ ```
 
 ## 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
-```
 
 Happy hacking!

 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 full featured implementation of the LBRY Network protocols and includes many useful components and tools for building decentralized applications. Primary features and components:
 
- * 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)).
- * Wallet implementation for the LBRY blockchain ([lbry.wallet](https://github.com/lbryio/lbry-sdk/tree/master/lbry/wallet)).
- * Daemon with a JSON-RPC API to ease building end user applications in any language and for automating various tasks ([lbry.extras.daemon](https://github.com/lbryio/lbry-sdk/tree/master/lbry/extras/daemon)).

+
+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 full featured implementation of the LBRY Network protocols and includes many useful components and tools for building decentralized applications. Primary features and components:
+
+ * 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/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/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/lbry/schema)).
+ * Wallet implementation for the LBRY blockchain ([lbry.wallet](https://github.com/lbryio/lbry-sdk/tree/master/lbry/lbry/wallet)).
+ * Daemon with a JSON-RPC API to ease building end user applications in any language and for automating various tasks ([lbry.extras.daemon](https://github.com/lbryio/lbry-sdk/tree/master/lbry/lbry/extras/daemon)). 
+
+## Installation
+
+Our [releases page](https://github.com/lbryio/lbry-sdk/releases) contains pre-built binaries of the latest release, pre-releases, and past releases for macOS, Debian-based Linux, and Windows. [Automated travis builds](http://build.lbry.io/daemon/) are also available for testing.
+
+## Usage
+
+Run `lbrynet start` to launch the API server.
+
+By default, `lbrynet` will provide a JSON-RPC server at `http://localhost:5279`. It is easy to interact with via cURL or sane programming languages.
+
+Our [quickstart guide](https://lbry.tech/playground) provides a simple walkthrough and examples for learning.
+
+With the daemon running, `lbrynet commands` will show you a list of commands.
+
+The full API is documented [here](https://lbry.tech/api/sdk).
+
+## Running from source
+
+Installing from source is also relatively painless. Full instructions are in [INSTALL.md](INSTALL.md)

-# Exceptions
-
-Exceptions in LBRY are defined and generated from the Markdown table at the end of this README.
-
-## Guidelines
-
-When possible, use [built-in Python exceptions](https://docs.python.org/3/library/exceptions.html) or `aiohttp` [general client](https://docs.aiohttp.org/en/latest/client_reference.html#client-exceptions) / [HTTP](https://docs.aiohttp.org/en/latest/web_exceptions.html) exceptions, unless:
-1. You want to provide a better error message (extend the closest built-in/`aiohttp` exception in this case).
-2. You need to represent a new situation.
-
-When defining your own exceptions, consider:
-1. Extending a built-in Python or `aiohttp` exception.
-2. Using contextual variables in the error message.
-
-## Table Column Definitions
-
-Column | Meaning
----|---
-Code | Codes are used only to define the hierarchy of exceptions and do not end up in the generated output, it is okay to re-number things as necessary at anytime to achieve the desired hierarchy.
-Name | Becomes the class name of the exception with "Error" appended to the end. Changing names of existing exceptions makes the API backwards incompatible. When extending other exceptions you must specify the full class name, manually adding "Error" as necessary (if extending another SDK exception).
-Message | User friendly error message explaining the exceptional event. Supports Python formatted strings: any variables used in the string will be generated as arguments in the `__init__` method. Use `--` to provide a doc string after the error message to be added to the class definition.
-
