+This is the drawio diagrams showing basic workflows inside RoadRunner 2.0
+
+Simple HTTP workflow description:
+![alt text](pool_workflow.svg)
+
+1. Allocate sync workers. When plugin starts (which use workers pool), then it allocates required number of processes
+ via `cmd.exec` command.
+
+2. When user send HTTP request to the RR2, HTTP plugin receive it and transfer to the workers pool `Exec/ExecWithContex`
+method. And workers pool ask Worker watcher to get free worker.
+
+3. Workers watcher uses stack data structure under the hood and making POP operation to get first free worker. If there are
+no workers in the `stack`, watcher waits for the specified via config (`allocate_timeout`) time.
+
+4. Stack returns free worker to the watcher.
+5. Watcher returns that worker to the `pool`.
+6. Pool invoke `Exec/ExecWithTimeout` method on the golang worker with provided request payload.
+7. Golang worker send that request to the PHP worker via various set of transports (`pkg/transport` package).
+8. PHP worker send back response to the golang worker (or error via stderr).
+9. Golang worker return response payload to the pool.
+10. Pool process this response and return answer to the user.
