+# Steam Ticket Generator
+
+This project provides an implementation of a encrypted app ticket generator for Steam. The generated ticket can then be used to run games that require a valid ticket to check for game ownership (ex. Denuvo protected games).
+
+**Note:** Denuvo protected games will also require to have the correct steam account id in the steam emulator settings.
+
+## Usage
+
+1. **Build the project:**
+
+    ```sh
+    cargo build --release
+    ```
+
+    The resulting binary will be located in `target/release/steam_ticket_generator.exe`.
+
+2. **Provide the steam_api64.dll file:**
+
+    Place the `steam_api64.dll` file in the same directory as the generated binary. This file is required to comunicate with the local Steam client.
+
+3. **Run the generator:**
+
+    Open steam on your computer, log in with the account you wish to use for the generation then run the program.
+    Input the game's AppID when prompted. The program will use the currently logged in account to generate the ticket.
+    It will output both the user's SteamID and the generated ticket in base64 format.
+
+4. **Use the generated ticket:**
+    It is possible to use the generated ticket with [GittyGittyKit's GBE Fork](https://github.com/GittyGittyKit/gbe_fork/releases) (that recently [merged](https://github.com/Detanup01/gbe_fork/pull/274) into the Detanup's fork 🎉).
+    Copy the generated SteamID and ticket to `configs.user.ini` in the `account_steamid` and `ticket` fields respectively.
+    ```ini
+    [user::general]
+    account_steamid=YOUR_STEAM_ID
+    ticket=BASE64_ENCODED_TICKET
+    ```
+
+## Builds
+
+Builds are available in the [releases](https://github.com/denuvosanctuary/steam-ticket-generator/releases) section of the repository. Nightly builds are also available in the [actions](https://github.com/denuvosanctuary/steam-ticket-generator/actions) section.
+
+The builds in the releases section will also include the `steam_api64.dll` file required to run the program. Otherwise you can download it from the [Steamworks SDK](https://partner.steamgames.com/doc/sdk). The minimum required version is 1.62.
