+# MochiWeb
 MochiWeb is an Erlang library for building lightweight HTTP servers.
 
-The latest version of MochiWeb is available at https://github.com/mochi/mochiweb
+## Overview
+MochiWeb provides a lightweight and fast solution for building HTTP servers in Erlang. The library provides features for building robust and scalable HTTP servers.
 
-The mailing list for MochiWeb is at https://groups.google.com/group/mochiweb/
+## Getting Started
+Before you can use MochiWeb, you'll need to have [Erlang OTP](https://www.erlang.org/) installed. Once you have Erlang OTP installed, you can download the latest version of MochiWeb from the [GitHub repository](https://github.com/mochi/mochiweb).
 
-Erlang OTP is required for setting up the MochiWeb environment and is available at https://www.erlang.org/
+For a MochiWeb project, first obtain a copy of MochiWeb using Git by running the command.
 
-To create a new mochiweb using project see the `example_project` in the `examples/` folder.
 
-Information about Rebar (Erlang build tool) is available at https://github.com/erlang/rebar3
+```erlang-repl
+$ git clone git://github.com/mochi/mochiweb.git.
+```
+To create a project.
 
-MochiWeb is currently tested with Erlang/OTP 18.3 through 24.0,
-versions older than 3.0.0 may still be compatible back to R15B-03.
+```erlang-repl
+$ cd mochiweb
+$ make app PROJECT=exampleName
+```
 
-# OTP 21.2, 21.2.1, 21.2.2 warning
+You can now start the project with.
+
+```erlang-repl
+$ cd ../exampleName/
+$ make
+$ ./start-dev.sh
+```
+
+You can access the app by navigating to http://localhost:8080 in your browser.
+
+For an example, view the `example_project` in the `examples/` folder.
+
+
+## Benefits
+* Lightweight: MochiWeb is designed to be lightweight and fast, making it ideal for use in resource-constrained environments.
+
+* Easy to use: MochiWeb provides a simple and intuitive API that makes it easy to get started with building HTTP servers.
+
+* Robust: MochiWeb provides a comprehensive set of features for building robust and scalable HTTP servers.
+
+## Documentations and Resources

+[Mailing list](https://groups.google.com/group/mochiweb/)
+
+## OTP 21.2, 21.2.1, 21.2.2 warning
 
 OTP 21.2 (up to and including 21.2.2) introduced an SSL regression that
 makes these releases unsafe to use. See [ERL-830](https://bugs.erlang.org/browse/ERL-830).
 This issue was resolved in OTP 21.2.3.
+
+
+## Contributing
+MochiWeb is an open-source project and welcomes contributions from the community.
