 #### Prototyping
 
 It is strongly recommended to prototype proposed conventions in one or more instrumentations and:

+# T-shaped Signals
+
+Semantic Conventions approaches observability with a T-shaped mindset. This
+splits signals into two types of a "T" shape:
+
+```mermaid
+block-beta
+        columns 3
+          Broad["Broadly Applicable Signals"]:3
+        columns 3
+          space:1
+          Deep("Rich,\nDeep\nSignals")
+          space:1
+```
+
+This matches an 80-20 rule, where 80% of users (or use-cases) can leverage the
+broadly applicable signals and 20% of users (or use-cases) will dive deeply into
+a problem with deep signals.
+
+## Broadly Applicable Signals
+
+These are conventions meant to provide a baseline observability experience
+across a domain. An example includes HTTP semantic conventions that allow
+general-purpose dashboarding, alerting, and diagnostics for HTTP
+(micro-)services. These signals should provide "horizontal" coverage for
+observability.
+
+Examples include:
+
+- Golden Signals / RED metrics (Saturation, Rate, Error, Duration)
+- High Level Spans
+- Error logs, Crash reports
+- Request/Response logs
+
+## Rich, Deep Signals
+
+These are conventions meant to provide deep understanding of a specific
+system, library, module, application or service. These are used to diagnose
+issues specific to that system.
+
+Examples include:
+
+- Linux slab memory usage
+- Specific database signals, e.g MySQL index usage
+- Language-specific Garbage Collection metrics (JVM, Go, .NET, etc.)
+
+## Recommendations
+
+Defining semantic conventions is a balance between generating
+broadly applicable signals and ensuring rich observability for a specific
+technology. It is recommended to start with the *broad* use cases and signals
+for a particular domain first. After providing a baseline set of signals for
+that domain, then explore deeper integrations that may be vendor or
+implementation specific.
+
+For example, see [Database semantic conventions](/docs/database/README.md) where
+there is general guidance for spans about communicating with a database, and
+additionally there is database-specific guidance as an extension of the general.
