For the standalone DCRDEX application, dexc, the latest release can always be found on GitHub. Download and extract the archive for your system, and from a command prompt in the extracted folder, run dexc. Open the displayed URL in the web browser of your choice.

Alternatively, launch DEX from within Decrediton, Decred's full-featured GUI wallet.

Detailed setup instructions are available on the wiki.

With DCRDEX opened in a browser or Decrediton, set a new "application password." Do not forget it!

Tip: Before moving on, retrieve the application "seed" from the settings page and store it in a safe place. This is used to restore wallets and accounts created by the DEX application. Click on the DCRDEX logo to resume setup.

Choose a server and you will be guided through setup of your wallets.

There are native (built-in to dexc) wallets for both Decred and Bitcoin. You may also use your own Electrum wallet for Bitcoin and Litecoin. For DOGE, ZEC, and BCH, use their full node wallets (e.g. dogecoind, zcashd, etc.).

For the native wallets, just click "Create!".

You can access the Wallets page at any time.

Once your wallets are synchronized, you will be prompted to submit a one-time fee before placing orders. This is a small amount just to discourage disruptive behavior.

The application will inform you how much is required in your new wallet to register. But deposit as much as you like to your wallet since only the required amount will be spent, and the remaining will be ready for trading. Deposits must confirm before proceeding. Then click "Register!" to proceed.

To place an order, fill out the price, the lot quantity, and submit it. Stay online and keep everything running until the trade settles.
