+# skyeweave
+
+Easily generate any FGO expression sheets from an id
+
+> Developed by [Firq](https://firq.dev/) and powered by the [AtlasAcademy API](https://atlasacademy.io/)
+
+## Installation
+
+The CLI can be installed by using `pip`. Python >= 3.10 is required.
+
+```shell
+pip install --extra-index-url https://forgejo.neshweb.net/api/packages/Firq/pypi/simple/ skyeweave
+```
+
+Note: Specifying the additional index of `forgejo.neshweb.net` is necessary, as I don't host my packages on PyPI. Using `--extra-index-url` is necessary as the
+specified depencencies are not hosted on that index.
+
+## Usage
+
+### commandline
+
+`skyeweave` is primarily a CLI application.
+
+The following options are available:
+
+- `--help` / `-h`: Shows helpful information about the other arguments
+- `--version`: Shows the version number
+- `--output`: Sets the output file path. This can be a relative path (`./out` or an absolute path `C:/files/out`)
+- `--id`: Specify a servantId or charaId. This will skip the user prompt afterwards (useful in CI applications)
+- `--filter`: Specify which spritesheets will actually be used. Useful if you want multiple spritesheets, but not all
+- `--timeout`: Sets the timeout for any requests towards the Atlas Academy API. The default is 10 seconds
+- `--no-cache`: Clear cache for this id, keeping all other files
+- `--reset`: Delete any already downloaded assets
+- `--quiet` / `-q`: Mute the output and hide progress bars
+
+Typical usage:
+
+```plain
+skyeweave --output out --id 70
+```
+
+This would generate the expressions for Scathach (Servant Id 70) in the folder out, using subfolders to better separate the outputs of multiple runs.
+
+### python scripts [EXPERIMENTAL]
+
+`skyeweave` can also be used in other Python scripts.
+
+```python
+from skyeweave import SkyeWeave
+SkyeWeave().compose(70)
+```
+
+This feature will be expanded upon in future releases.
+
+## Issues / Support
+
+If there are any issues with `skyeweave`, feel free to reach out to me using the AtlasAcademy discord (`#dev-corner`) or create an issue in this repo.
+
+If you want to help me debug when an issue occurs, set the environment variable `SKYEWEAVE_STDOUT_LEVEL` to `debug` and send me a copy of the log
+
+Example on Windows:
+
+```shell
+$env:SKYEWEAVE_STDOUT_LEVEL="debug"
+
+skyeweave --output out --id 70 > log.log
+```
