Please make the documentation more clear

Hi Paraswap Team,

can you improve the documention. Things that i stumpled accross and would make the devs live easier:

• high level archicture how the lib is basically working and what functions from a dex integration are called
• Better code documentation. There some basic comments on the test files, but for example there could be more documentation in the template files where devs need to complete the code
• Please make it clear what environment variables should be set. It looks like that the Tenderly variables are not enough. For example you also need the HTTP Provider set for each chain (e.g for Fantom HTTP_PROVIDER_250)

Thanks in advance,
