+## Overview
+
+This project has a console application [also a web api, mentioned below] written in c# which connects to the `Uniswap API v3` and collects the liquidity positions
+of both the cryptocurrencies of a user defined liquidity pool.
+
+Below are the information it fetches and shows them on console (in addition to writting them in log files).
+
+- Position of token0 (USDC in this example)
+- Position of token1 (ETH in this example)
+- Current price of token0:token1 (USDC per ETH in this example)
+
+Example: Lets say, you want to fetch the below highlighted information for pool id [245953](https://app.uniswap.org/#/pool/245953).
+
+![Uniswap Interface](./images/245953.png)
+
+Run the application and here is the output information fetched from `Uniswap API v3`.
+
+![Console output](./images/output.png)
+
+**Note:**
+- You can set the pool id, precisions and also the interval after which the application should fetch the information from `Uniswap API v3`.
+
+```
+# app.config
+
+  <appSettings>
+    <add key="PoolId" value="245953" />
+    <add key="PrecisionForPosition0" value="3" />
+    <add key="PrecisionForPosition1" value="6" />
+    <add key="PrecisionForCurrentPrice" value="2" />
+    <add key="IntervalInSeconds" value="60" />
+  </appSettings>
+```
+- You can also control the output by customizing configuration in `log4net.config`. (eg.: change the log directory, pattern, rolling style etc.)
+
+```
+# log4net.config
+  <root>
+    <level value="ALL" />
+    <!--<appender-ref ref="console" />-->
+    <appender-ref ref="file" />
+  </root>
+```
+- When network is disconnected/fluctuated, It retries in a smart way which automatically calculates the number of retries to be done exponentially based on `IntervalInSeconds` provided
+in `app.config`. For example: for a given interval 60 seconds, lets say first trigger is at `10:30`. If Uniswap API can not be connected, then there will be maximum 4 retries (auto calculated).
+	- First retry will be done after 5 seconds `[10:30:05]`
+	- 2nd retry will be done after 10 seconds `[10:30:15]`
+	- 3rd retry will be done after 15 seconds `[10:30:30]`
+	- 4th retry will be done after 20 seconds `[10:30:50]`
+	- If API still can not be connected, then send error `Unable to retrieve the data from server after 4 retries.`
+	- A new timer will be triggered at `[10:31:00]`.
+
+- There is also an webapi project, which exposes endpoint `positions` to allow you fetch the same information. Please check [demo](https://uniswap-v3.vercel.app/positions/245953) url.
+
+![API output](./images/api.png)
+
+**Note:**
+- Format of api is `positions/<pool_id>/<token0_precision>/<token1_precision>/<currentprice_precision>`. Few examples:
+	- https://uniswap-v3.vercel.app/positions/245953  => Shows the information with no truncation.
+	- https://uniswap-v3.vercel.app/positions/245953/3 => Truncates only token0 position with 3 decimal precision
+	- https://uniswap-v3.vercel.app/positions/245953/3/6  => Truncates token0 position with 3 decimal precisions and token1 position with 6 precision.
+	- https://uniswap-v3.vercel.app/positions/245953/null/null/2 =>  Truncate only current price with 2 decimal precision.
