+# What are these files?
+
+These files are the DWARF data generated for (an early version of) this
+library. Each file corresponds is a section from the built library's object
+file. By splitting the sections out to their own files, we don't need to worry
+about cross platform and cross object file format issues when running examples.
+
+# Updating and adding new sections
+
+## macOS
+
+Use `otool` to list the sections of a binary:
+
+```
+$ otool -l path/to/binary
+```
+
+You should see output similar to this:
+
+```
+Load command 0
+      cmd LC_SEGMENT_64
+  cmdsize 72
+  segname __PAGEZERO
+   vmaddr 0x0000000000000000
+   vmsize 0x0000000100000000
+  fileoff 0
+ filesize 0
+  maxprot 0x00000000
+ initprot 0x00000000
+   nsects 0
+    flags 0x0
+Load command 1
+      cmd LC_SEGMENT_64
+  cmdsize 712
+  segname __TEXT
+   vmaddr 0x0000000100000000
+   vmsize 0x00000000001b7000
+  fileoff 0
+ filesize 1798144
+  maxprot 0x00000007
+ initprot 0x00000005
+   nsects 8
+    flags 0x0
+Section
+  sectname __text
+   segname __TEXT
+      addr 0x0000000100000a50
+      size 0x0000000000170716
+    offset 2640
+     align 2^4 (16)
+    reloff 0
+    nreloc 0
+     flags 0x80000400
+ reserved1 0
+ reserved2 0
+```
+
+Etc.
+
+Find the `Section` entry of the section you'd like to isolate. For example, if
+you're looking for `eh_frame`, find an entry like this:
+
+```
+Section
+  sectname __eh_frame
+   segname __TEXT
+      addr 0x0000000100192f38
+      size 0x00000000000240c8
+    offset 1650488
+     align 2^3 (8)
+    reloff 0
+    nreloc 0
+     flags 0x00000000
+ reserved1 0
+ reserved2 0
+```
+
+Then use `dd` to copy `size` bytes starting from `offset`:
+
+```
+$ dd bs=1 skip=1650488 count=$(printf "%d" 0x00000000000240c8) if=path/to/binary of=fixtures/self/eh_frame
+```
+
+Finally, use `otool` and `hexdump` to verify that the isolated section has the
+same data as the section within the binary:
+
+```
+$ otool -s __TEXT __eh_frame path/to/binary | head
+path/to/binary:
