-Web app for checking tmt tests and plans
-# Run instructions
-1. Create a virtual environment
-2. Install the requirements
-3. Use the `start_api.sh` script to start the api
+# tmt web
+
+Web application for checking tmt tests, plans and stories.
+
+## Run instructions
+
+To run the service locally for development purposes, use the following command:
+
+```bash
+podman-compose up --build
+```
+
+Add `-d` for the service to run in the background.
+
 ## Tests
-To run the tests, use the pytest command
-# API
-API for checking tmt tests and plans metadata
-## Version
-The API version is defined by prefix in url, e.g.
-`/v0.1/status`
-## Endpoints
-* `/` - returns ID of the created Celery task with additional metadata in JSON and callback url for `/status` endpoint, 
-returns the same in HTML format if `format` is set to `html`
-  * `test-url` - URL of the repo test is located in - accepts a `string`
 
-  * `test-ref` - Ref of the repository the test is located in - accepts a `string`, 
-  defaults to default branch of the repo
+To run the tests, use the `pytest` command (assuming the service is running).
+
+Alternatively, if you have `hatch` installed, `hatch run test:run` command will
+rebuild, start the service and run the tests.
+
+## Environment variables
+
+- `REDIS_URL` - *optional*, passed to Celery on initialization as a `broker` and
+  `backend` argument, default value is: `redis://localhost:6379`
+- `CLONE_DIR_PATH` - *optional*, specifies the path where the repositories will
+  be cloned, default value is: `./.repos/`
+- `USE_CELERY` - *optional*, specifies if the app should use Celery, set to
+  `false` for running without Celery
+- `API_HOSTNAME` - *required*, specifies the hostname of the API, used for
+  creating the callback URL to the service
+
+## API
+
+The API version is defined by prefix in url, e.g. `/v0.1/status`.
+
+If we want to display metadata for both tests and plans, we can combine
+the `test-*` and `plan-*` options together, they are not mutually
+exclusive.
+
+`test-url` and `test-name`, or `plan-url` and `plan-name` are required.
+
+### `/`
+

+and callback url for `/status` endpoint, returns the same in HTML format
+if `format` is set to `html`.
+
+  * `test-url` - URL of the repo test is located in - accepts a `string`
+  * `test-ref` - Ref of the repository the test is located in - accepts
+    a `string`, defaults to default branch of the repo
   * `test-path` - Points to directory where `fmf` tree is stored
   * `test-name` - Name of the test - accepts a `string`
+
   * `plan-url` - URL of the repo plan is located in - accepts a `string`
-
-  * `plan-ref` - Ref of the repository the plan is located in - accepts a `string`, 
-  defaults to default branch of the repo
+  * `plan-ref` - Ref of the repository the plan is located in - accepts
+    a `string`, defaults to default branch of the repo
   * `plan-path` - Points to directory where `fmf` tree is stored
   * `plan-name` - Name of the plan - accepts a `string`
-  * `format` - Format of the output - accepts a `string`, default is `json`, other options are `xml`, `html`
-  (serves as a basic human-readable output format)
+
+  * `format` - Format of the output - accepts a `string`, default is
+    `json`, other options are `xml`, `html` (serves as a basic
+    human-readable output format)
   * `id` - Unique ID of the tmt object
-* `/status` - returns a status of the tmt object being processed by the backend
+
+### `/status`
+
+Returns a status of the tmt object being processed by the backend.
+
   * `task_id` - ID of the task - accepts a `string`
-* `/status/html` - returns a status of the tmt object being processed by the backend in a simple HTML formatting
+
+### `/status/html`
+
+Returns a status of the tmt object being processed by the backend in a
+simple HTML formatting.
+
   * `task_id` - ID of the task - accepts a `string`
-* `/health` - returns a health status of the service
 
-If we want to display metadata for both tests and plans, we can combine the `test-*`
-and `plan-*` options together, they are not mutually exclusive.
+### `/health`
 
-`test-url` and `test-name`, or `plan-url` and `plan-name` are required.
