+# Forgejo
+
+Not available until the next release <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+## Introduction
+
+The Testcontainers module for [Forgejo](https://forgejo.org/), a self-hosted Git forge. Forgejo is a community-driven fork of Gitea, providing a lightweight code hosting solution.
+
+## Adding this module to your project dependencies
+
+Please run the following command to add the Forgejo module to your Go dependencies:
+
+```sh
+go get github.com/testcontainers/testcontainers-go/modules/forgejo
+```
+
+## Usage example
+
+<!--codeinclude-->
+[Creating a Forgejo container](../../modules/forgejo/examples_test.go) inside_block:runForgejoContainer
+<!--/codeinclude-->
+
+## Module Reference
+
+### Run function
+
+- Not available until the next release <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+The Forgejo module exposes one entrypoint function to create the Forgejo container, and this function receives three parameters:
+
+```golang
+func Run(ctx context.Context, img string, opts ...testcontainers.ContainerCustomizer) (*Container, error)
+```
+
+- `context.Context`, the Go context.
+- `string`, the Docker image to use.
+- `testcontainers.ContainerCustomizer`, a variadic argument for passing options.
+
+#### Image
+
+Use the second argument in the `Run` function to set a valid Docker image.
+In example: `Run(context.Background(), "codeberg.org/forgejo/forgejo:11")`.
+
+### Container Options
+
+When starting the Forgejo container, you can pass options in a variadic way to configure it.
+
+#### Admin Credentials
+
+- Not available until the next release <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+Use `WithAdminCredentials(username, password, email)` to set the admin user credentials. An admin user is automatically created when the container starts. Default credentials are `forgejo-admin` / `forgejo-admin`.
+
+#### Configuration via Environment
+
+- Not available until the next release <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+Use `WithConfig(section, key, value)` to set Forgejo configuration values using the `FORGEJO__section__key` environment variable format. See the [Forgejo Configuration Cheat Sheet](https://forgejo.org/docs/latest/admin/config-cheat-sheet/) for available options.
+
+{% include "../features/common_functional_options_list.md" %}
+
+### Container Methods
+
+The Forgejo container exposes the following methods:
+
+#### ConnectionString
+
+- Not available until the next release <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+The `ConnectionString` method returns the HTTP URL for the Forgejo instance (e.g. `http://localhost:12345`).
+
+#### SSHConnectionString
+
+- Not available until the next release <a href="https://github.com/testcontainers/testcontainers-go"><span class="tc-version">:material-tag: main</span></a>
+
+The `SSHConnectionString` method returns the SSH endpoint for Git operations.
