-A few resources are available as starting points to getting involved and understanding the project:
+## Compiling from source
+Building jvnkosu! from source is pretty much possible (and welcome here).  
 
-- Detailed release changelogs are available on the [official osu! site](https://osu.ppy.sh/home/changelog/lazer).
-- You can learn more about our approach to [project management](https://github.com/ppy/osu/wiki/Project-management).
-- Track our current efforts [towards improving the game](https://github.com/orgs/ppy/projects/7/views/6).
+First, you must have a desktop platform with [.NET Core SDK 8](https://dotnet.microsoft.com/download) installed. Windows, Linux, macOS should work well. You can check if you have the SDK installed by running `dotnet --version` in your command prompt/terminal.  
 
-## Running osu!
-
-If you are just looking to give the game a whirl, you can grab the latest release for your platform:
-
-### Latest release:
-
-| [Windows 10+ (x64)](https://github.com/ppy/osu/releases/latest/download/install.exe) | macOS 12+ ([Intel](https://github.com/ppy/osu/releases/latest/download/osu.app.Intel.zip), [Apple Silicon](https://github.com/ppy/osu/releases/latest/download/osu.app.Apple.Silicon.zip)) | [Linux (x64)](https://github.com/ppy/osu/releases/latest/download/osu.AppImage) | [iOS 13.4+](https://osu.ppy.sh/home/testflight) | [Android 5+](https://github.com/ppy/osu/releases/latest/download/sh.ppy.osulazer.apk) |
-|--------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| ------------- | ------------- | ------------- |
-
-You can also generally download a version for your current device from the [osu! site](https://osu.ppy.sh/home/download).
-
-If your platform is unsupported or not listed above, there is still a chance you can run the release or manually build it by following the instructions below.
-
-**For iOS/iPadOS users**: The iOS testflight link fills up very fast (Apple has a hard limit of 10,000 users). We reset it occasionally. Please do not ask about this. Check back regularly for link resets or follow [peppy](https://twitter.com/ppy) on twitter for announcements. Our goal is to get the game on mobile app stores very soon so we don't have to live with this limitation.
-
-## Developing a custom ruleset
-
-osu! is designed to allow user-created gameplay variations, called "rulesets". Building one of these allows a developer to harness the power of the osu! beatmap library, game engine, and general UX for a new style of gameplay. To get started working on a ruleset, we have some templates available [here](https://github.com/ppy/osu/tree/master/Templates).
-
-You can see some examples of custom rulesets by visiting the [custom ruleset directory](https://github.com/ppy/osu/discussions/13096).
-
-## Developing osu!
-
-### Prerequisites
-
-Please make sure you have the following prerequisites:
-
-- A desktop platform with the [.NET 8.0 SDK](https://dotnet.microsoft.com/download) installed.
-
-When working with the codebase, we recommend using an IDE with intelligent code completion and syntax highlighting, such as the latest version of [Visual Studio](https://visualstudio.microsoft.com/vs/), [JetBrains Rider](https://www.jetbrains.com/rider/), or [Visual Studio Code](https://code.visualstudio.com/) with the [EditorConfig](https://marketplace.visualstudio.com/items?itemName=EditorConfig.EditorConfig) and [C# Dev Kit](https://marketplace.visualstudio.com/items?itemName=ms-dotnettools.csdevkit) plugin installed.
-
-### Downloading the source code
-
-Clone the repository:
-
-```shell
-git clone https://github.com/ppy/osu
-cd osu
+Then, download the source code. You may download it as an archive and unzip it, but using [Git](https://git-scm.com/) instead is recommended:
+```
+git clone https://gitea.jvnko.boats/jvnkosu/client
 ```
 
-To update the source code to the latest commit, run the following command inside the `osu` directory:
 
-```shell
-git pull
+To **run** the project, switch to project's directory and run the following:
 ```
-
-### Building
-
-#### From an IDE
-
-You should load the solution via one of the platform-specific `.slnf` files, rather than the main `.sln`. This will reduce dependencies and hide platforms that you don't care about. Valid `.slnf` files are:
-
-- `osu.Desktop.slnf` (most common)
-- `osu.Android.slnf`
-- `osu.iOS.slnf`
-
-Run configurations for the recommended IDEs (listed above) are included. You should use the provided Build/Run functionality of your IDE to get things going. When testing or building new components, it's highly encouraged you use the `osu! (Tests)` project/configuration. More information on this is provided [below](#contributing).
-
-To build for mobile platforms, you will likely need to run `sudo dotnet workload restore` if you haven't done so previously. This will install Android/iOS tooling required to complete the build.
-
-#### From CLI
-
-You can also build and run *osu!* from the command-line with a single command:
-
-```shell
 dotnet run --project osu.Desktop
 ```
 
-When running locally to do any kind of performance testing, make sure to add `-c Release` to the build command, as the overhead of running with the default `Debug` configuration can be large (especially when testing with local framework modifications as below).
-
-If the build fails, try to restore NuGet packages with `dotnet restore`.
-
-### Testing with resource/framework modifications
-
-Sometimes it may be necessary to cross-test changes in [osu-resources](https://github.com/ppy/osu-resources) or [osu-framework](https://github.com/ppy/osu-framework). This can be quickly achieved using included commands:
-
-Windows:
-
-```ps
-UseLocalFramework.ps1
-UseLocalResources.ps1
+To **compile**:
+```
+dotnet build osu.Desktop
 ```
 
-macOS / Linux:
+To reduce performance overhead in custom builds, it's recommended to build with the `-c Release` flag, that will use the release profile and remove possibly unneeded debugging code.
 
-```ps
-UseLocalFramework.sh
-UseLocalResources.sh
-```
-
-Note that these commands assume you have the relevant project(s) checked out in adjacent directories:
-
-```
-|- osu            // this repository
-|- osu-framework
-|- osu-resources
-```
-
-### Code analysis
-
-Before committing your code, please run a code formatter. This can be achieved by running `dotnet format` in the command line, or using the `Format code` command in your IDE.
-
-We have adopted some cross-platform, compiler integrated analyzers. They can provide warnings when you are editing, building inside IDE or from command line, as-if they are provided by the compiler itself.
-
-JetBrains ReSharper InspectCode is also used for wider rule sets. You can run it from PowerShell with `.\InspectCode.ps1`. Alternatively, you can install ReSharper or use Rider to get inline support in your IDE of choice.
-

When testing or building new components, it's highly encouraged you use the `osu! (Tests)` project/configuration. More information on this is provided [below](#contributing).
+
+To build for mobile platforms, you will likely need to run `sudo dotnet workload restore` if you haven't done so previously. This will install Android/iOS tooling required to complete the build.
+
+#### From CLI
+
+You can also build and run *osu!* from the command-line with a single command:
+
+```shell
+dotnet run --project osu.Desktop
+```
+
+When running locally to do any kind of performance testing, make sure to add `-c Release` to the build command, as the overhead of running with the default `Debug` configuration can be large (especially when testing with local framework modifications as below).
+
+If the build fails, try to restore NuGet packages with `dotnet restore`.
+
+### Testing with resource/framework modifications
+
+Sometimes it may be necessary to cross-test changes in [osu-resources](https://github.com/ppy/osu-resources) or [osu-framework](https://github.com/ppy/osu-framework). This can be quickly achieved using included commands:
+
+Windows:
+
+```ps
+UseLocalFramework.ps1
+UseLocalResources.ps1
+```
+
+macOS / Linux:
+
+```ps
+UseLocalFramework.sh
+UseLocalResources.sh
+```
+
+Note that these commands assume you have the relevant project(s) checked out in adjacent directories:
+
+```
+|- osu            // this repository
+|- osu-framework
+|- osu-resources
+```
+
+### Code analysis
+
+Before committing your code, please run a code formatter. This can be achieved by running `dotnet format` in the command line, or using the `Format code` command in your IDE.
+
+We have adopted some cross-platform, compiler integrated analyzers. They can provide warnings when you are editing, building inside IDE or from command line, as-if they are provided by the compiler itself.
+
+JetBrains ReSharper InspectCode is also used for wider rule sets. You can run it from PowerShell with `.\InspectCode.ps1`. Alternatively, you can install ReSharper or use Rider to get inline support in your IDE of choice.
