Claude Complete Setup Guide in 1 Day

1: Cowork Download Claude. Open the Cowork tab. Select a folder from your computer. Create your brain file. Create "about-me.md." Start each chat with this prompt: "Lee los archivos primero. Luego hazme preguntas antes de hacer cualquier cosa." 2: Model Choose Opus 4.6 (best model right now). Enable Extended Thinking. Go to Settings > Connectors. Link Slack, Google Drive, Notion. Claude now reads your real workspace. 3: Excel Open Excel. Go to Insert > Get Add-ins. Search "Claude by Anthropic." Install. Open any spreadsheet. Ask: "Dame un resumen de cada pestaña." Claude lives inside the spreadsheet. Knows exactly what cell D14 contains. 4: Plugins Go to the plugin directory. Choose the one matching your job. Marketing. Sales. Legal. Finance. Data. Click install. Type / in your next chat. 5: Artifacts Nothing to install. Ask Claude to build something. "Crea una calculadora HTML interactiva para [cosa]." You get a functional tool inside the chat. Not text. Not a suggestion. Something you can click and use. 6: Projects Go to Projects. Create one. Upload your files and add instructions. Each chat within the project remembers your context.
