If you are outside the project's directory, you can specify the path

pop build -p ./my-appchain

For Pop CLI versions <0.3.0 the pop build command is pop build parachain

If you are building the parachain with the intent to onboard the parachain to a Polkadot Relay chain then you can run the following build command:

pop build -p ../my-appchain --para_id 2000

This command will build your parachain and generate the chain spec, WebAssembly runtime for the parachain, and generate the parachain genesis state needed for registering and onboarding a parachain onto the Relay chain.
