 Audio transcoder with simple HTTP API. Work in progress.
 
-# What works
+# How to Use
 
-Transcoding:
-1. `cargo run`
+Transcoding can be done like this:
+1. Use `cargo run` or [`neur0toxine/atranscoder-rpc`](https://hub.docker.com/r/neur0toxine/atranscoder-rpc/) Docker image.
 2. Upload file for transcoding:
 ```bash
 curl --location 'http://localhost:8090/enqueue' \

     --form 'channelLayout="mono"' \
     --form 'uploadUrl="http://127.0.0.1:8909/upload"'
 ```
-3. You will receive JSON response with job ID. The transcoding result will be saved into `/tmp/{job_id}.out.atranscoder`
+3. Your `uploadUrl` will receive JSON response with job ID and error in case of failure and the entire transcoded file contents in case of success. Use `Content-Type` header to differentiate between the two data types.
+
+You can change configuration using this environment variables:
+- `LISTEN` - change this environment variable to change TCP listen address. Default is `0.0.0.0:8090`.
+- `NUM_WORKERS` - can be used to change how many threads will be used to transcode incoming files. Default is equal to logical CPUs.
+- `TEMP_DIR` - this can be used to change which directory should be used to store incoming downloads and transcoding results. Useful if you want to use a Docker volume for this. Default is system temp directory (`/tmp` for Linux).
+- `LOG_LEVEL` - changes log verbosity, default is `info`.
 
 # Roadmap
-- [ ] ~~Restart threads in case of panic.~~ It's better to not panic. Current error handling seems ok for now.
 - [x] Implement somewhat acceptable error handling.
 - [x] Remove old conversion results and input files that are older than 1 hour.
 - [x] Remove input file after transcoding it.
 - [x] Implement file upload to `uploadUrl` (if `Content-Type: application/json` then conversion was not successful and body contains an error info).
 - [x] Remove transcoding result after uploading it to the `uploadUrl`.
 - [x] Docker image for `amd64` and `aarch64`.
+- [ ] ~~Restart threads in case of panic.~~ It's better to not panic. Current error handling seems ok for now.
 - [ ] ~~Statically linked binary for Docker image & result docker image based on `scratch` (reduce image size).~~ Not yet, see [Dockerfile.scratch](Dockerfile.scratch).
 - [ ] Tests!
