+The assembly Solnet.KeyStore contains constructs and utility methods necessary to save and restore wallets as well as encrypt and decrypt keystores.
 It includes an implementation of the [Web3 Secret Storage Definition](https://github.com/ethereum/wiki/wiki/Web3-Secret-Storage-Definition) which generates a JSON file with an encrypted keystore, with only the correct password being necessary to decrypt it. It also includes a simpler keystore implementation that is capable of restoring keys generated by the `solana-keygen` CLI tool.
 
 The KeyStore depends on the Solnet.Wallet project assembly, plus [Chaos.NaCl](https://github.com/p3root/Chaos.NaCl/) and [BouncyCastle](https://github.com/novotnyllc/bc-csharp).
 
 ## Solnet.Programs
 
 The Solnet.Programs assembly implements and abstracts the usage of several Solana programs. These programs are either the [Native Programs](https://docs.solana.com/developing/runtime-facilities/programs) or part of the [SPL](https://spl.solana.com/).
-If you're looking for more specific implementations, than you may have to look at [Solnet.Serum](https://github.com/bmresearch/Solnet.Serum), Solnet.Pyth, Solnet.Mango or even start your own using our APIs.
