 ## Welcome to Thanix!
 
-Thanix is an experimental cli application written in Rust for generating Rust code from yaml schema files like they are found as openAPI schemas.
+Thanix is an experimental cli application written in Rust for generating Rust code from yaml schema files like they are
+found as openAPI schemas.
+
+## Installation
+
+Be aware that Thanix currently is only developed on and for Linux distributions.<br>
+Support for other operating systems may be available in the future, but currently though it is not guaranteed to work.
+
+### Building from source
+
+Building from source provides you with the most recent updates and changes to Thanix. However, be aware that these
+may be unstable, so downloading a tagged release is advised.
+
+Also, make sure you **have the Rust programming language and Cargo installed**.
+
+To build Thanix from source you need to follow these steps:
+
+1. Download the source code. To do so, run this command in your Terminal:
+
+```bash
+git clone git@github.com:The-Nazara-Project/Thanix.git
+```
+
+This will create a new directory called `Thanix`, move into it.
+
+2. Run the application directly
+
+You can now run Thanix using the `cargo run` command. However, this process may take longer and may feel less
+comfortable.
+
+**Do not forget to pass the required CLI parameters to Thanix when doing this.**
+
+```bash
+cargo run -- --input-file $PATH_TO_YOUR_YAML --uri $URI_TO_YOUR_API
+```
+
+This may look like this:
+
+```bash
+cargo run -- --input-file ./api_config.yaml --uri https://demo.netbox.dev
+```
+
+> **NOTE:** Make sure that you **do not end your URI with a slash (/)**. As this would mangle the API paths.
+
+This step will result in your `thanix_client` being generated.
+
+To view the next steps please scroll **down to the Usage section**.
+
+Optional:
+
+3. Install Thanix using `cargo install`.
+
+You can also install the crate on your system, so you always have it available.
+To do so, run this command while in the Thanix project directory:
+
+```bash
+cargo install --path .
+```
+
+This will install Thanix onto your system and it can be executed by simply running `thanix` in your terminal.
+
+### Install Thanix using Cargo
+
+Thanix is also published on [crates.io](https://crates.io).
+
+To install it simply run:
+
+```bash
+cargo install thanix
+```
+
+### Install Cargo as a distribution package (TBA)
+
+We are working on building packages for a variety of Linux distributions starting with `openSUSE Tumbleweed`.
+
+We will update you as soon as we have news.
+
+## Usage
+
+After you have installed Thanix in a way you see fit, you use it by passing it **two mandatory parameters** like this:
+
+```bash
+thanix --input-file $YOUR_API_YAML --uri $YOUR_API_URI
+```
+
+- The `--input-file` parameter is a path to your `.yaml`-file you want to use as an input. This is usually the API
+  schema file your want to generate a client for.
+- The `--uri` is the URI to your API in a format like this: `https://demo.netbox.dev`.
+  **Make sure this URI does not end with a `/`**
