-# LBRY Comment Server v2
+# LBRY Comment Server
 
-This is a rewrite & update of the server 
+This is the code for the LBRY Comment Server. 
-[written by myself and Grayson Burton here](https://github.com/ocornoc/lbry-comments)
+Fork it, run it, set it on fire. Up to you.
 
-### Install & Setup
 
-Clone the repo and install a virtual environement: 
+## Prerequisites 
+In order to run the comment server properly, you will need the 
+following: 
  
+ 0. A Unix Compliant Operating System (e.g: Ubuntu, RedHat, Hannah Montana, etc.) 
+ 1. Any recent version of Sqlite3
+ 2. Python 3.6+ (including `python3-dev`, `python3-virtualenv`, `python3-pip`)
+    Note: You must specify the specific python version you're using,
+    e.g. for Python3.6, you would install `python36-dev`. You're smart enough to figure the rest out from here ;)
+ 3. (Optional) Reverse Proxy software to handle a public-facing API. 
+    We recommend Caddy, though there is an `nginx.conf` file under `config`.
+ 4. Patience (Strongly recommended but often neglected)
+ 
+## Installation
+
+Installing the server:
 ```bash
-# clone the repo
-$ git clone https://github.com/osilkin98/comment-server
 
-# create a virtual environment in any (current) version of python3.X
+$ git clone https://github.com/osilkin98/comment-server
+$ cd comment-server
+
+# create a virtual environment
 $ virtualenv --python=python3 venv
+
+# Enter the virtual environment
 $ source venv/bin/activate
 
-# install the dependencies
+# install the library dependencies
 (venv) $ pip install -r requirements.txt
 ```
 
-### Running the server
+## Usage
 
-Just run:
+### Running the Server
-`(venv) $ python -m src.main.py`
+To start the server, simply run:
-and it should run automatically.
+```bash
+# to enter server's venv
+$ source venv/bin/activate
 
+# To start server as daemon process
+(venv) $ python -m main &  
+```
+
+### Testing
+
+To Test the database, simply run: 
+```bash
+# To run the whole thing :
+(venv) $ python -m unittest tests.database
+
+# To run a specific TestName under a specified TestClass:
+(venv) $ python -m unittest tests.database.TestClass.TestName` 
+``` 
+
+There are basic tests to run against the server, though they require 
+that there is a server instance running, though the database
+ chosen may have to be edited in `config/conf.json`.
+
+Additionally there are HTTP requests that can be send with whatever 
+software you choose to test the integrity of the comment server.

-## About
+## Contributing
-A lot of the design is more or less the same with the original,
+Contributions are welcome, verbosity is encouraged. Please be considerate
-except this version focuses less on performance and more on scalability. 
+in your posts, and make sure that you give as much context to the issue 
+as possible, so that helping you is a slam dunk for us.
 
-Rewritten with python because it's easier to adjust 
+### Issues
-and maintain. Instead of doing any multithreading, 
+If you spotted an issue from the SDK side, please replicate it using 
-this implementation just delegates a single 
+`curl` and one of the HTTP request templates in `tests/http_requests`. 
-database connection for write operations. 
 
-The server was originally implemented with `aiohttp` 
+Then, just include that along with the rest of your information.
-and uses `aiojobs` for scheduling write operations.
+
-As pointed out by several people, Python is a dinosaur 
+### Pull Requests
-in comparison to SQLite's execution speed, 
+Make sure the code works and has been tested beforehand. 
-so there is no sensibility in multi-threading from the 
+Although we love helping out, our job is to review your code,
-perspective of the server code itself. 
+not test it - that's what your computer is for. 
+
+
+Try to document the changes you made in a human language, 
+preferably English. (but we're always up for a challenge...)
+Use the level of verbosity you feel is correct, and when in doubt, 
+just [KISS](https://people.apache.org/~fhanik/kiss.html).
