```
#### Make a change to `faasd`
There are two components you can hack on:
For function CRUD you will work on `faasd provider` which is started from `cmd/provider.go`
For faasd itself, you will work on the code from `faasd up`, which is started from `cmd/up.go`
Before working on either, stop the systemd services:
```
sudo systemctl stop faasd & # up command
sudo systemctl stop provider # provider command
```
Here is a workflow you can use for each code change:
Enter the directory of the source code, and build a new binary:
```bash
cd $GOPATH/src/github.com/openfaas/faasd
go build
```
Copy that binary to `/usr/local/bin/`
```bash
cp faasd /usr/local/bin/
```
To run `faasd up`, run it from its working directory as root
```bash
sudo -i
cd /var/lib/faasd
faasd up
```
Now to run `faasd provider`, run it from its working directory:
```bash
sudo -i
cd /var/lib/faasd-provider
faasd provider
```
#### At run-time
Look in `hosts` in the current working folder or in `/var/lib/faasd/` to get the IP for the gateway or Prometheus
