-= Git Webhook Client
-
-Git webhook client that runs commands after a webhook event and shows their output.
-
-Currently, only Gitea is supported. If you want support for Gitlab or Github, then please open an issue.
-
-== Features
-
-* Verify the webhook event with a secret.
-* Run a configured command to a specific repository on a webhook event.
-* Save the output of the command.
-* Show an output by visiting the url of the client.
-* Supported configuration for multiple repositories.
-* Written in Rust :D
-
-== Getting started
-
-=== Requirements
-
-* `cargo` to compile the source code.
-* Development package for SQLite (`sqlite-devel` on Fedora)
-
-=== Configuration
-
-The program looks for the configuration file configured with the environment variable `GWC_CONFIG_FILE` that contains the following:
-
-. `secret`: The secret of the webhook.
-. `base_url`: The base_url of the webhook client.
-. `hooks`: List of webhooks.
-.. `repo_url`: Repository url.
-.. `current_dir`: The directory to run the command in.
-.. `command`: The command without any arguments.
-.. `args`: List of arguments separated by a comma.
-
-==== Example configuration file:
-
-[source, json]
-----
-{
-  "secret": "CHANGE_ME!",
-  "base_url": "https://webhook.mo8it.xyz",
-  "hooks": [
-    {
-      "repo_url": "https://codeberg.org/Mo8it/git-webhook-client",
-      "current_dir": ".",
-      "command": "ls",
-      "args": ["-l", "-a", "test_directory"]
-    }
-  ]
-}
-----
-
-==== First setup
-
-* Clone the repository.
-* Create the configuration file.
-* Run the following to initialize the database:
-.
-[source, bash]
-----
-cargo install diesel_cli --no-default-features --features sqlite
-DATABASE_URL=PATH/TO/DATABASE/DIRECTORY/db.sqlite diesel_cli migration run
-cargo build --release
-----
-
-==== Run
-
-After running `cargo build --release`, the binary can be found in the directory `target/release/git-webhook-client`. To run it, you have to specify the environment variable `DATABASE_URL`:
-
-[source, bash]
-----
-DATABASE_URL=PATH/TO/DATABASE/DIRECTORY/db.sqlite target/release/git-webhook-client
-----
-
-==== Setup on the git server
-
-Setup the webhook for the configured repositories on the git server. Don't forget to enter the same secret that you did specify in the configuration file.
-
-==== Show output
-
-After an event, the client responds with a URL that shows the log. The id in that URL is important and specific to this event.
-
-If you want to see the last log, just visit the `base_url` from the configuration.
-
-To see a specific log with an id, visit the URL: `base_url/?id=THE_ID_OF_AN_EVENT`.
-
-You can specify a negative ID to see the last events. `id=-1` corresponds to the last log, `id=-2` corresponds to the log before it and so on.
-
-== Note
-
-This is my first Rust project and I am still learning. If you have any suggestions, just open an issue!

+# Git Webhook Client
+
+Git webhook client that runs commands after a webhook event and shows their output.
+
+Currently, only Gitea is supported. If you want support for Gitlab or Github, then please open an issue.
+
+## Features
+
+- Verify the webhook event with a secret.
+- Run a configured command to a specific repository on a webhook event.
+- Save the output of the command.
+- Show an output by visiting the url of the client.
+- Supported configuration for multiple repositories.
+- Written in Rust :D
+
+## Getting started
+
+### Requirements
+
+- `cargo` to compile the source code.
+- Development package for SQLite (`sqlite-devel` on Fedora)
+
+### Configuration
+
+The program looks for the configuration file configured with the environment variable `GWC_CONFIG_FILE` that contains the following:
+
+<!-- TODO: Adjust to new config -->
+
+1. `secret`: The secret of the webhook.
+1. `base_url`: The base_url of the webhook client.
+1. `hooks`: List of webhooks.
+1. `repo_url`: Repository url.
+1. `current_dir`: The directory to run the command in.
+1. `command`: The command without any arguments.
+1. `args`: List of arguments separated by a comma.
+
+#### Example configuration file:
+
+<!-- TODO: Adjust to new config -->
+
+```yaml
+secret: CHANGE_ME!
+base_url: https://webhook.mo8it.com
+
+hooks:
+  repo_url: https://codeberg.org/Mo8it/git-webhook-client
+  current_dir: .
+  command: ls
+  args: ["-l", "-a", "test_directory"]
+```
+
+#### First setup
+
+<!-- TODO: Auto migration -->
+
+- Clone the repository.
+- Create the configuration file.
+- Run the following to initialize the database:
+  ```bash
+  cargo install diesel_cli --no-default-features --features sqlite
+  DATABASE_URL=PATH/TO/DATABASE/DIRECTORY/db.sqlite diesel_cli migration run
+  cargo build --release
+  ```
+
+#### Run
+
+After running `cargo build --release`, the binary can be found in the directory `target/release/git-webhook-client`. To run it, you have to specify the environment variable `DATABASE_URL`:
+
+```bash
+DATABASE_URL=PATH/TO/DATABASE/DIRECTORY/db.sqlite target/release/git-webhook-client
+```
+
+#### Setup on the git server
+
+Setup the webhook for the configured repositories on the git server. Don't forget to enter the same secret that you did specify in the configuration file.
+
+#### Show output
+
+After an event, the client responds with a URL that shows the log. The id in that URL is important and specific to this event.
+
+If you want to see the last log, just visit the `base_url` from the configuration.
+
+To see a specific log with an id, visit the URL: `base_url/?id=THE_ID_OF_AN_EVENT`.
