IT Documentation refers to the structured recording, organization, and management of all technical knowledge required to operate, maintain, and support IT environments. Unlike general-purpose wikis (covered in Wiki & Knowledge Base), IT documentation platforms are purpose-built for managed service providers (MSPs) and internal IT teams, providing specialized features for per-client documentation, credential storage, network diagrams, runbooks, and asset-level configuration records.
IT documentation platforms serve as the single source of truth for technicians working across multiple customer environments. They answer critical questions:
- What is deployed? – servers, network devices, cloud services, applications, and their configurations per client
- How do I access it? – credentials, VPN details, remote access instructions, and escalation contacts per client
- How do I fix it? – SOPs, runbooks, and troubleshooting guides for recurring issues
- What has changed? – configuration history, change logs, and audit trails
- What is expiring? – SSL certificates, warranties, licenses, and contracts with automated alerts
Without dedicated IT documentation, knowledge lives in technician memories, scattered notes, shared spreadsheets, and sticky notes – creating dangerous single points of failure, inconsistent service delivery, and compliance gaps.

The information on these pages was researched by a combination of human review and large language models. This catalogue serves as a reference for the resources, applications, devices, deployment payloads, and other components that the ResorsIT platform integrates, deploys, and manages. To suggest an addition or correction, please contact us. Prepared by Rhodium Systems Inc., author of the ResorsIT platform — a unified IT operations management platform for IT teams and MSPs that integrates a curated suite of open-source, commercial, and SaaS applications into a single system with shared identity, single sign-on, access control, and a common audit trail. This information is compiled on a best-effort basis: it may be incomplete, contain errors, and become out of date as tools, vendors, licences, and features change. Use this catalogue only as a starting point for your own research, and independently verify and review any tool carefully against your own requirements before relying on it.
